For example, the electronic device can participate in communication when the external electronic device is a compatible, authorized device intended (or dedicated) to access the identification information, thereby preventing security vulnerabilities or the risk of leakage of user personal information. The above technical effects are merely exemplary and not limiting. Additional advantages will be apparent to those skilled in the art.
[0022] FIG. 1 is a block diagram showing the configuration of an electronic device according to one embodiment.
[0023] Referring to FIG. 1, according to one embodiment, an electronic device (101) can communicate with an external electronic device (103). For example, the external electronic device (103) can communicate with the electronic device (101) to obtain identification information of the electronic device (101). According to one embodiment, the electronic device (101) can communicate with the external electronic device (103) through a direct connection.
[0024] According to one embodiment, the electronic device (101) may be connected to an external electronic device (103) to transmit identification information to the external electronic device (103) in an off state. For example, when the electronic device (101) is connected to the external electronic device (103) while the processor (140) is in a powered off or inactive state, the electronic device (101) may obtain a power voltage from the external electronic device (103). For example, when the electronic device (101) obtains a power voltage from the external electronic device (103), at least some circuits (e.g., the identification information transmission circuit (160)) of the electronic device (101) may be activated. For example, the electronic device (101) may obtain identification information from the external electronic device (103) using the activated identification transmission circuit (160).
[0025] According to one embodiment, the electronic device (101) may be connected to an external electronic device (103) to transmit identification information to the external electronic device (103) in an on state. For example, when the electronic device (101) is connected to the external electronic device (103) while the processor (140) is in a powered-on or activated state, the electronic device (101) may check the power voltage from the external electronic device (103). If the power voltage checked from the external electronic device (103) is within a certain range, the electronic device (101) may transmit identification information of the electronic device (101) to the external electronic device (103).
[0026] According to one embodiment, the electronic device (101) can communicate with the external electronic device (103) through at least one of 1-wire (single wire), USB (universal serial bus) (e.g., USB type A, USB type B, USB type C), I2C (inter-integrated circuit), SPI (serial peripheral interface), SMB (system management bus), or UNI / O. According to one embodiment, the communication method through direct connection between the electronic device (101) and the external electronic device (103) is not limited thereto. For example, the electronic device (101) can communicate with the external electronic device (103) through a communication method including at least one of MMC (multimedia card), PCI-E (peripheral component interconnect-express), SATA (serial advanced technology attachment), PATA (parallel advanced technology attachment), SCSI (small computer system interface), ESDI (enhanced small device interface), or IDE (integrated drive electronics).
[0027] According to one embodiment, the electronic device (101) may include a connection terminal (110) (e.g., the connection terminal (1178) of FIG. 11), at least one transmission line (e.g., the transmission line (120), the wired communication module (1194) and / or the interface (1177) of FIG. 11), a power management circuit (PMIC) (130) (e.g., the power management module (1188) of FIG. 1), at least one processor (e.g., the processor (140) and the processor (1120) of FIG. 11), a first memory (150) (e.g., the memory (1130) of FIG. 11), and an identification information transmission circuit (160). For example, the electronic device (101) may include any electronic device such as a smart phone, a laptop, a desktop, a TV, a smart pad, a tablet PC, a wearable device, a connected car, and / or a portable terminal.
[0028] According to one embodiment, the electronic device (101) can be connected to an external electronic device (103) via a connection terminal (110). According to one embodiment, the connection terminal (110) can include a connector. The connector can physically connect the electronic device and the external electronic device. For example, the connection terminal (101) can include an HDMI connector, a USB connector, an SD card connector, or an audio connector (e.g., a headphone connector).
[0029] According to one embodiment, when the electronic device (101) and the external electronic device (103) are connected via a USB C type connection terminal (e.g., connection terminal (110)), the transmission line (120) may include any pin line (e.g., VBUS pin line, CC (configuration channel) pin line, SBU (sideband use) line, etc.) of the USB C type connection terminal. For example, the pin line may be connected to a pin of the connection terminal (110). For example, the pin line may correspond to at least a part of a transmission line (e.g., transmission line (120)) that electrically connects the pin of the connection terminal (110) and internal components of the electronic device (101).
[0030] According to one embodiment, the electronic device (101) can obtain a voltage from an external electronic device (103) connected to the connection terminal (110) through a transmission line (120). According to one embodiment, the electronic device (101) can obtain a voltage within a first preset range from the external electronic device (103) through the transmission line (120). For example, the first preset range may correspond to a range greater than or equal to a first voltage and less than or equal to a second voltage. For example, the second voltage may correspond to a voltage lower than a minimum voltage for turning on the electronic device (101). For example, the second voltage may correspond to a voltage lower than a minimum voltage for activating the processor (140) of the electronic device (101). For example, the first voltage may correspond to a minimum voltage for activating the identification information transmission circuit (160). For example, when the voltage obtained from the external electronic device (103) is within a preset first range (for example, when the obtained voltage is greater than or equal to the first voltage and less than or equal to the second voltage), the electronic device (101) may activate the identification information transmission circuit (160) when the electronic device (101) is turned off (for example, when the processor (140) is deactivated).
[0031] According to one embodiment, the electronic device (101) can obtain a voltage within a preset second range from an external electronic device (103) through a transmission line (120). For example, the preset second range may correspond to a range greater than or equal to a third voltage and less than or equal to a fourth voltage. For example, the third voltage may correspond to a voltage greater than the second voltage. For example, the third voltage may correspond to a minimum voltage for turning on the electronic device (101). For example, the fourth voltage may correspond to a maximum voltage for turning on the electronic device (101). For example, the third voltage may correspond to a minimum voltage for activating the processor (140) of the electronic device (101). For example, the fourth voltage may correspond to a maximum voltage that the external electronic device (103) can apply to the electronic device (101). For example, the fourth voltage may correspond to the maximum voltage that can be applied to the electronic device (101) set by the electronic device (101). For example, the fourth voltage may correspond to the maximum voltage for activating the processor (140) of the electronic device (101). For example, when the voltage acquired from the external electronic device (103) is within the preset second range (for example, when the acquired voltage is 31 volts or more and 4th voltage or less), the electronic device (101) may deactivate the identification information transmission circuit (160) when the electronic device (101) is turned on (for example, when the processor (140) is activated).
[0032] According to one embodiment, the electronic device (101) may obtain a voltage within a preset third range from an external electronic device (103) via a transmission line (120). For example, the preset third range may correspond to a range lower than or equal to a first voltage. For example, if the voltage obtained from the external electronic device (103) is lower than the first voltage, all components of the electronic device (101) may not be activated or may not operate.
[0033] According to one embodiment, the electronic device (101) is described as being capable of obtaining voltage from an external electronic device (103), but is not limited thereto. For example, the electronic device (10) may obtain voltage, current, and / or power from the external electronic device (103). For example, the external electronic device (103) may apply (or supply) voltage, current, and / or power to the electronic device (101).
[0034] According to one embodiment, a power management integrated circuit (PMIC) (130) can manage power supplied to an electronic device (101). According to one embodiment, the power management circuit (130) can receive a voltage (or power, current) applied to the electronic device (101) from an external electronic device (103). The power management circuit (130) can supply at least a portion of the received voltage (or power, current) to the processor (140) to activate the processor (140). The power management circuit (130) can be referenced by the power management module (1188) of FIG. 11.
[0035] According to one embodiment, at least one processor may be electrically connected to components of the electronic device (101). For example, at least one processor (e.g., processor (140)) may be connected to a connection terminal (110), at least one transmission line (e.g., transmission line (120)), a first memory (150), and an identification information transmission circuit (160). For example, at least one processor may be wiredly connected to components of the electronic device (101). The at least one processor may be composed of a single chip or multiple chips. For example, the at least one processor may include at least one processing circuitry including a central processing unit (CPU), an application processor (AP), a microprocessor unit (MPU), a communication processor (CP), a system on chip (SoC), and / or an integrated circuit (IC).
[0036] According to one embodiment, the first memory (150) and / or the second memory (165) may include built-in memory and / or external memory. For example, the built-in memory may include at least one of a volatile memory (e.g., dynamic random access memory (DRAM), static random access memory (SRAM), or synchronous DRAM (SDRAM)), a non-volatile memory (e.g., programmable read-only memory (PROM), one time PROM (OTPROM), erasable PROM (EPROM), electrically erasable and PROM (EEPROM), mask ROM, flash ROM, flash memory, a hard drive, or a solid state drive (SSD). The external memory may include at least one of a flash drive (e.g., compact flash), secure digital (SD), micro-SD, mini-SD, extreme digital (xD), multi-media card (MMC), or memory stick.
[0037] According to one embodiment, the first memory (150) may store instructions that can be executed by at least one processor (e.g., processor (140)). The first memory (150) may store at least one data related to the operation of the electronic device (101) or a command related to the functional operation of components of the electronic device (101). For example, the first memory (150) may store at least one application that is preloaded when the electronic device (101) is manufactured or downloaded as a third party from an online market (e.g., app store). For example, the at least one application may include a voice recognition application that supports the operation of a voice recognition service. According to one embodiment, the first memory (150) may store identification information of the electronic device (101). For example, if the identification information transmission circuit (160) does not include the second memory (165), the first memory (150) can store the identification information of the electronic device (101).
[0038] According to one embodiment, the identification information transmission circuit (160) can transmit identification information of the electronic device (101) to an external electronic device (103). For example, the identification information can include a unique number (e.g., international mobile equipment identity (IMEI)) for identifying the electronic device (101). According to one embodiment, the identification information transmission circuit (160) can include a switching circuit (161), a control circuit (163), and a second memory (165).
[0039] According to one embodiment, the second memory (165) can store identification information of the electronic device (101). According to one embodiment, the control circuit (163) can store identification information of the electronic device (101) in the second memory (165). According to one embodiment, the second memory (165) of the identification information transmission circuit (160) can be omitted. For example, if the second memory (165) is omitted, the identification information of the electronic device (101) can be stored in the first memory (150).
[0040] According to one embodiment, the control circuit (163) can transmit identification information of the electronic device (101) to the external electronic device (103). For example, when a voltage within a preset first range is applied from the external electronic device (103) connected to the connection terminal (110) while the electronic device (101) is turned off, the control circuit (163) can be activated. For example, when the control circuit (163) is activated, it can transmit identification information of the electronic device (101) to the external electronic device (130). For example, the control circuit (163) can be activated even when the electronic device (101) is turned on.
[0041] According to one embodiment, the processor (140) can read identification information stored directly in the second memory (165) while the electronic device (101) is turned on. The processor (140) can transmit the read identification information of the electronic device (101) to an external electronic device (103).
[0042] According to one embodiment, the switching circuit (161) can change the state of the switch (e.g., the switching element (S1) of FIG. 4) from the first state to the second state when a voltage within a preset first range is applied. For example, the first state can correspond to an open state of the switch. For example, the second state can correspond to a closed state of the switch. According to one embodiment, the switching circuit (161) can open the switch when a voltage within the preset first range is not applied from the external electronic device (103). According to one embodiment, the switching circuit (161) can close the switch when a voltage within the preset first range is applied from the external electronic device (103). The switching circuit (161) can close the switch when a voltage within the preset first range is applied, and can open the switch when a voltage within the preset second range (e.g., a voltage greater than or equal to a third voltage and less than or equal to a fourth voltage) is applied. According to one embodiment, the switching circuit (161) may electrically connect the control circuit (163) and the connection terminal (110) when the switch is short-circuited. For example, when the switching circuit (161) short-circuits the switch, the control circuit (163) may be activated when the electronic device (101) is in an off state. For example, when a voltage within a preset first range is applied, the identification information transmission circuit (160) may be activated when the electronic device (101) is in an off state. The switching circuit of the present disclosure may be configured in various ways. For example, the switching circuit may be configured in various ways according to any one of FIGS. 4, 5, 7, and 8 as discussed below, or according to any other suitable arrangement known in the art. Therefore, embodiments of the present disclosure are not limited by the structure of the switching circuit.
[0043] According to one embodiment, the switching circuit (161) can electrically disconnect the control circuit (163) and the connection terminal (110) when the switch is opened. The switching circuit (161) can isolate the identification information transmission circuit (160) from at least one of the other components of the electronic device (101) (e.g., the connection terminal (410), the transmission line (120)) by disconnecting the control circuit (163) and the connection terminal (110).
[0044] According to one embodiment, when the control circuit (163) is electrically connected to the connection terminal (110), it can transmit identification information of the electronic device (101) to the external electronic device (103) using the transmission line (120). For example, when the control circuit (163) is electrically connected to the connection terminal (110) and communication with the external electronic device (103) is enabled, it can transmit identification information of the electronic device (101) stored in the second memory (165) to the external electronic device (103).
[0045] According to one embodiment, the control circuit (163) may transmit identification information using the same transmission line (120) as the transmission line (120) to which voltage is applied from the external electronic device (103). For example, when voltage is applied from the external electronic device (103) through a first transmission line (e.g., a VBUS pin line of a USB C type connection terminal), the control circuit (163) may transmit identification information of the electronic device (101) to the external electronic device (103) using the same first transmission line. The control circuit (163) may also transmit identification information using a different transmission line (120) from the transmission line (120) to which voltage is applied from the external electronic device (103). For example, when voltage is applied from an external electronic device (103) through a first transmission line (e.g., a VBUS pin line of a USB C type connection terminal), the control circuit (163) can transmit identification information of the electronic device (101) using a second transmission line (e.g., a CC pin line of a USB C type connection terminal) that is different from the first transmission line.
[0046] According to one embodiment, the control circuit (163) may perform an authentication function when electrically connected to the connection terminal (110). According to one embodiment, the control circuit (163) may receive authentication information from the external electronic device (103) when electrically connected to the connection terminal (110). For example, the authentication information may correspond to information for determining the validity of the external electronic device (103) to transmit identification information of the electronic device (101) to the control circuit (163). For example, determining the validity of the external electronic device (103) may include determining whether the control circuit (163) can transmit identification information of the electronic device (101). For example, if the identification information of the electronic device (101) is transmitted to any external device, security may be vulnerable or a risk of personal information leakage may occur. The control circuit (163) can transmit identification information of the electronic device (101) to the authenticated external electronic device (103) based on the validity judgment of the external electronic device (103). For example, the control circuit (164) can prevent the identification information of the electronic device (101) from being transmitted to any unauthenticated external electronic device by transmitting the identification information of the electronic device (101) to the external electronic device that has successfully been authenticated based on the authentication information received from the external electronic device.
[0047] According to one embodiment, the control circuit (163) may receive authentication information from the external electronic device (103) and compare it with authentication information stored in the second memory (165). If the authentication information received from the external electronic device (103) matches the authentication information stored in the second memory (165), the control circuit (163) may transmit identification information of the electronic device (101) to the external electronic device (103).
[0048] Each of the components of the electronic device (101) described above may include a single or multiple entities. For example, some of the multiple entities may be separately arranged in other components. According to one embodiment, one or more of the components of the electronic device (101) described above may be omitted, or one or more other components may be added. According to one embodiment, the components of the electronic device (101) may omit at least some of the operations of the components of the electronic device (101) described above (e.g., operations of the control circuit (163)), or may additionally perform one or more other operations.
[0049] FIG. 2 is a flowchart illustrating a method for an electronic device to transmit identification information to an external electronic device, according to one embodiment. In the following, any description that overlaps with the description of FIG. 1 may be omitted or briefly described.
[0050] In operation 210, an electronic device (e.g., an electronic device (101) of FIG. 1) can obtain a voltage from an external electronic device (e.g., an external electronic device (103) of FIG. 1) connected to a connection terminal (e.g., a connection terminal (110) of FIG. 1) through a first transmission line (e.g., a transmission line (120) of FIG. 1). For example, the electronic device (101) can obtain a voltage from the external electronic device (103) through the first transmission line (120) in a turned-off state.
[0051] In operation 230, the electronic device (101) may electrically connect the connection terminal (110) and the control circuit (163) when the acquired voltage is within a preset first range. For example, the control circuit (163) may be electrically connected to the connection terminal (110) when the voltage acquired by the electronic device (101) from the external electronic device (103) is within the preset first range. According to one embodiment, when the electronic device (101) is in a default state, the connection terminal (110) and the control circuit (163) may be electrically disconnected. For example, the default state may include a state in which the electronic device (101) is not connected to the external electronic device (103) and / or a state in which a voltage within a preset second range is applied from the external electronic device (103) connected via the connection terminal (110). According to one embodiment, the electronic device (101) may electrically connect the connection terminal (110) and the control circuit (163) when a voltage within a preset first range is obtained from an external electronic device (103) in a basic state. For example, the preset first range may correspond to a voltage range lower than a voltage for activating the electronic device (101). For example, even when a voltage within the preset first range is applied from the external electronic device (103), the electronic device (101) may be in an off state (e.g., a state in which the processor (140) is deactivated).
[0052] In operation 250, the electronic device (101) may transmit identification information of the electronic device (101) through a first transmission line (e.g., transmission line (120) of FIG. 1). According to one embodiment, the electronic device (101) may be connected to an external electronic device (103) through a connection terminal (110) to perform wired communication. According to one embodiment, the control circuit (163) may be activated when electrically connected to the connection terminal (110). The electronic device (101) may transmit identification information to the external electronic device (103) using the activated control circuit (163). The electronic device (101) may transmit identification information to the external electronic device (103) using a 1-wire communication method. For example, the electronic device (101) may transmit identification information to the external electronic device (103) using a power line communication (PLC) method.
[0053] The order of the operations described above with respect to FIG. 2 is merely an example and embodiments of the present disclosure are not limited thereto. For example, at least some of the operations may be performed in a different order than that of FIG. 2, or may be performed substantially concurrently with other operations of FIG. 2. At least some of the operations described above with respect to FIG. 2 may be omitted.
[0054] FIG. 3 is a flowchart illustrating a method for an electronic device to transmit identification information to an external electronic device, according to one embodiment. In the following, any description that overlaps with the description in FIG. 1 may be omitted or briefly described.
[0055] In operation 310, an electronic device (e.g., an electronic device (101) of FIG. 1) may obtain a voltage from an external electronic device (e.g., an external electronic device (103) of FIG. 1) connected to a connection terminal (e.g., a connection terminal (110) of FIG. 1) through a first transmission line (e.g., a transmission line (120) of FIG. 1). Hereinafter, descriptions overlapping with those of FIG. 2 may be omitted or briefly described. Operation 310 may be referenced by operation 210 of FIG. 2.
[0056] In operation 320, the electronic device (101) can determine whether the acquired voltage is within a preset first range. For example, the preset first range is as described above in FIG. 1. For example, the preset first range may correspond to a range greater than or equal to a first voltage and less than or equal to a second voltage. For example, the range greater than or equal to the first voltage and less than or equal to the second voltage may correspond to a range less than a minimum voltage for turning on the electronic device (101). For example, the range greater than or equal to the first voltage and less than or equal to the second voltage may correspond to a range less than a minimum voltage for activating the processor (140) of the electronic device (101).
[0057] According to one embodiment, the electronic device (101) can detect a voltage applied through the first transmission line and determine whether the obtained voltage is within a preset first range. For example, the electronic device (101) can use a comparator to determine whether the applied voltage is within the preset first range. A method for determining whether the applied voltage is within the preset first range using a comparator may be further described in FIG. 4.
[0058] If the voltage acquired from the external electronic device (103) is within a preset second range (e.g., operation 320-No), in operation 325, the electronic device (101) may open a switch of a switching circuit (e.g., the switching circuit (161) of FIG. 1). For example, the preset second range may correspond to a range of voltage applied by a general USB device rather than a dedicated host device for acquiring identification information of the electronic device (101). According to one embodiment, the electronic device (101) may open a switch of the switching circuit (161) if the acquired voltage is within the preset second range. For example, the electronic device (101) may open the switch of the switching circuit (161) to electrically disconnect the connection terminal (110) and the control circuit (163). According to one embodiment, the electronic device (101) can electrically disconnect the connection terminal (110) and the control circuit (163) to deactivate the control circuit (163). For example, the electronic device (101) can deactivate the control circuit (163) to electrically isolate the identification information transmission circuit (160) from at least one of the other components of the electronic device (101) (e.g., the connection terminal (110), the transmission line (120)). If the voltage obtained from the external electronic device (103) is within a preset first range (e.g., operation 320-Yes), in operation 330, the electronic device (101) can close the switch of the switching circuit (163). For example, the electronic device (101) may short-circuit the switch of the switching circuit (163) even when the electronic device (101) is turned off, if the voltage obtained from the external electronic device (103) is within a preset first range. According to one embodiment, the electronic device (101) may short-circuit the switch of the switching circuit (161) to electrically connect the connection terminal (110) and the control circuit (163).The electronic device (101) can activate the control circuit (163) by electrically connecting the connection terminal (110) and the control circuit (163).
[0059] In operation 340, the control circuit (163) may receive authentication information from the external electronic device (103) via the first transmission line. According to one embodiment, the control circuit (163) may receive authentication information from the external electronic device (103) when the switch of the switching circuit (161) is short-circuited and the control circuit (163) is activated. For example, the authentication information may correspond to information for determining the validity of the external electronic device (103) to transmit identification information to the control circuit (163). For example, the authentication information may include information related to a request for identification information from the electronic device (101).
[0060] At operation 350, the control circuit (163) may determine whether the received authentication information is valid. In one embodiment, the control circuit (163) may receive the authentication information from the external electronic device (103) and compare it with the authentication information stored in the second memory (165). For example, if the authentication information received from the external electronic device (103) matches the authentication information stored in the second memory (165), the control circuit (163) may determine that the received authentication information is valid. If the received authentication information does not match the authentication information stored in the second memory (165) (e.g., operation 350-No), the electronic device (101) may request the authentication information and / or perform operation 340 again to receive the authentication information from the external electronic device (103).
[0061] If it is determined that the authentication information received from the external electronic device (103) is valid (e.g., operation 350-Yes), in operation 360, the control circuit (163) may transmit the identification information of the electronic device (101) to the external electronic device (103) via the first transmission line. According to one embodiment, the control circuit (163) may transmit the identification information to the external electronic device (103) using a 1-wire communication method. For example, if the received authentication information is valid, the control circuit (163) may transmit the identification information via the same first transmission line as the first transmission line to which voltage is supplied. If the received authentication information is valid, the control circuit (163) may read the identification information of the electronic device (101) stored in the second memory (165). The control circuit (163) may transmit the read identification information to the external electronic device (103).
[0062] The order of the operations described above with respect to FIG. 3 is merely an example and embodiments of the present disclosure are not limited thereto. For example, at least some of the operations may be executed differently from the order of FIG. 3, or may be executed substantially simultaneously with other operations of FIG. 3. At least some of the operations described above with respect to FIG. 3 may be omitted.
[0063] FIG. 4 is a circuit diagram for transmitting identification information from an electronic device to an external electronic device, according to one embodiment. In the following, any description that overlaps with the description of FIG. 3 may be omitted or briefly described.
[0064] According to one embodiment, an electronic device (401) (e.g., the electronic device (101) of FIG. 1) may be connected to an external electronic device (403) (e.g., the external electronic device (103) of FIG. 1) via a connection terminal (410) (e.g., the connection terminal (110) of FIG. 1). According to one embodiment, the electronic device (401) may include a connection terminal (410), a transmission line (420), a power management circuit (430) (e.g., the power management circuit (130) of FIG. 1), and an identification information transmission circuit (440) (e.g., the identification information transmission circuit (160) of FIG. 1). The identification information transmission circuit (440) may include a switching circuit (441) (e.g., the switching circuit (161) of FIG. 1), a control circuit (443) (e.g., the control circuit (163) of FIG. 1), and a second memory (445) (e.g., the second memory (165) of FIG. 2). An external electronic device (403) may be electrically connected to components of the electronic device (401) (e.g., a connection terminal (410), a power management circuit (430), and an identification information transmission circuit (440)) via a transmission line (420) (e.g., a transmission line (120) of FIG. 1).
[0065] According to one embodiment, the connection terminal (410) can receive voltage from an external electronic device (403) to which it is electrically connected. For example, the external electronic device (403) can include a general USB device and / or a dedicated host device for obtaining identification information of the electronic device (401). The connection terminal (410) can electrically connect a power management circuit (430) and an identification information transmission circuit (440) to the external electronic device (403).
[0066] According to one embodiment, the identification information transmission circuit (440) can receive a voltage applied from an external electronic device (403) connected to the connection terminal (110) through the transmission line (420). According to one embodiment, the identification information transmission circuit (440) can be deactivated when the electronic device (401) is in a default state. For example, the identification information transmission circuit (440) can electrically disconnect the control circuit (443) and the connection terminal (410) in the default state. For example, the default state can include a state in which the electronic device (401) is not connected to the external electronic device (403) and / or a state in which a voltage within a preset second range is applied from the external electronic device (403).
[0067] According to one embodiment, when the voltage applied from the external electronic device (403) is within a preset first range, the identification information transmission circuit (440) may be activated. According to one embodiment, the switching circuit (441) may electrically connect the control circuit (443) and the connection terminal (410) when the voltage applied from the external electronic device (403) connected to the connection terminal (410) is within a preset first range. For example, the switching circuit (441) may electrically connect the control circuit (443) and the connection terminal (410) when the applied voltage is within the preset first range, by using a switching element (S1), two comparators (A1, A2), and an AND gate element (G1).
[0068] According to one embodiment, the two comparators (A1, A2) can output a signal indicating a comparison result according to the voltage applied through the transmission line (420). According to one embodiment, the comparator (A1) can output a high level signal when the voltage applied to the + input terminal through the transmission line (420) is equal to or greater than the first voltage (V1), and can output a low level signal when the voltage is less than the first voltage (V1) or when no voltage is applied. For example, a high level signal can include a digital signal of 1, and a low level signal can include a digital signal of 0. The comparator (A2) can output a high level signal when the voltage applied to the - input terminal through the transmission line (420) is equal to or less than the second voltage (V2), and can output a low level signal when it is greater than the second voltage (V2).
[0069] According to one embodiment, the signals output through the two comparators (A1, A2) can be input to the AND gate element (G1). According to one embodiment, the switching element (S1) can be opened or closed based on the signals output through the two comparators (A1, A2). For example, when the voltage applied from the external electronic device (403) through the transmission line (420) is greater than or equal to the first voltage (V1) and less than or equal to the second voltage (V2) (e.g., when the output signal of G1 is at a high level), the switching element (S1) can be closed. For example, when the voltage applied from the external electronic device (403) through the transmission line (420) is less than the first voltage (V1) or greater than the second voltage (V2) or when there is no applied voltage (e.g., when the output signal of G1 is at a low level), the switching element (S1) can be opened. For example, in the embodiment of FIG. 4, the electronic device (401) can activate the identification information transmission circuit (440) even when the electronic device (401) is turned off, if a dedicated host device that applies a voltage within a preset first range is connected. If a general USB device is connected to the electronic device (401), a normal voltage within a preset second range is applied, so the switching element (S1) can be opened. When the switching element (S1) is opened, the identification information transmission circuit (440) can be deactivated.
[0070] Referring to FIG. 4, the switching circuit (441) is illustrated as including two comparators (A1, A2) and one AND gate element (G1), but is not limited thereto. For example, the switching circuit (441) may not include a comparator. For example, the switching circuit (441) may include at least one comparator. For example, the switching circuit (441) may include at least one logic circuit gate element, or may be configured without a logic circuit gate element.
[0071] According to one embodiment, when the magnitude of the voltage applied through the transmission line (420) from the external electronic device (403) connected to the connection terminal (410) is greater than or equal to the first voltage (V1) and less than or equal to the second voltage (V2), the control circuit (443) may be electrically connected to the connection terminal (410) and activated. According to one embodiment, when the control circuit (443) is activated, the control circuit (443) may receive authentication information from the external electronic device (403) through the transmission line (420). The control circuit (443) may determine whether the received authentication information is valid. For example, the operation of the control circuit (443) receiving authentication information and the operation of determining whether the received authentication information is valid may be referred to by operations 340 and 350 of FIG. 3.
[0072] According to one embodiment, if the control circuit (443) determines that the received authentication information is valid, it can transmit identification information of the electronic device (401) to the external electronic device (403). According to one embodiment, if the received authentication information is valid, the control circuit (443) can transmit identification information of the electronic device (401) stored in the second memory (445) to the external electronic device (403). For example, the control circuit (443) can read identification information of the electronic device (401) stored in the second memory (445). For example, the control circuit (443) can transmit identification information of the electronic device (401) read from the second memory (445) to the external electronic device (403) via the transmission line (420).
[0073] According to one embodiment, the processor (e.g., the processor (140) of FIG. 1) may identify the identification information of the electronic device (401) stored in the second memory (445) by using a circuit portion different from the transmission line (420) when the switching element (S1) is opened and the identification information transmission circuit (440) is deactivated. For example, the processor may identify the identification information of the electronic device (401) stored in the second memory (445) by using another circuit portion (not shown) electrically connected to the second memory (445) when the electronic device (401) is in a powered-on state and / or an activated state. In one embodiment, the processor may transmit the identification information of the identified electronic device (401) to an external electronic device (403).
[0074] FIG. 5 is a circuit diagram for transmitting identification information to an external electronic device by an electronic device according to one embodiment. In the following, any description that overlaps with the description of FIG. 4 may be omitted or briefly described.
[0075] According to one embodiment, an electronic device (501) (e.g., an electronic device (101) of FIG. 1) may be connected to an external electronic device (503) (e.g., an external electronic device (103) of FIG. 1, an external electronic device (403) of FIG. 4) via a connection terminal (510) (e.g., a connection terminal (110) of FIG. 1, a connection terminal (410) of FIG. 4). According to one embodiment, the electronic device (501) may include a connection terminal (510), a transmission line (520), a power management circuit (530) (e.g., a power management circuit (130) of FIG. 1, a power management circuit (430) of FIG. 4) and an identification information transmission circuit (540) (e.g., an identification information transmission circuit (160) of FIG. 1, an identification information transmission circuit (440) of FIG. 4). The identification information transmission circuit (540) may include a switching circuit (541) (e.g., the switching circuit (161) of FIG. 1, the switching circuit (441) of FIG. 4), a control circuit (543) (e.g., the control circuit (163) of FIG. 1, the control circuit (443) of FIG. 4), and a PLC circuit (545). The external electronic device (503) may be electrically connected to at least one of the components of the electronic device (501) (e.g., the connection terminal (110), the power management circuit (530), and / or the identification information transmission circuit (540)) via a transmission line (520) (e.g., the transmission line (120) of FIG. 1).
[0076] According to one embodiment, the identification information transmission circuit (540) can activate the control circuit (543) when the voltage applied from the external electronic device (503) is within a preset first range. According to one embodiment, the switching circuit (541) can electrically disconnect the control circuit (543) and the connection terminal (510) when the electronic device (501) is in a default state. The default state is as described above in FIG. 4. For example, when the external electronic device (503) is not connected and there is no voltage applied through the transmission line (520), there is no voltage applied to the source of the first switch (the first switch (Q1)), so the first switch (Q1) can be turned off. For example, when a first voltage higher than a certain level that can turn on the first switch (Q1) is applied from an external electronic device (503), the first voltage may be applied to the source of the first switch (Q1). When the first voltage is applied to the source of the first switch (Q1), the gate voltage of the first switch (Q1) is pulled down, so the first switch (Q1) may be turned on. For example, when a second voltage that is higher than the first voltage and the breakdown voltage (Vz) of the zener diode (D1) is applied from the external electronic device (503), a voltage may be applied to the gate of the third switch (Q3). When a voltage is applied to the gate of the third switch (Q3), the third switch (Q3) may be turned on. When the third switch (Q3) is turned on, the gate of the second switch (Q2) may be connected to ground. When the gate of the second switch (Q2) is connected to the ground, voltage is applied to the source of the second switch (Q2) from an external electronic device, so the second switch (Q2) can be turned on. When the second switch (Q2) is turned on, the magnitudes of the source voltage and the gate voltage of the first switch (Q1) can become equal. When the source voltage and the gate voltage of the first switch (Q1) become equal, the first switch (Q1) can be turned off.According to one embodiment, the switching circuit (541) may turn on the first switch (Q1) when the voltage applied from the external electronic device (503) through the transmission line (520) is greater than or equal to the first voltage and less than or equal to the second voltage. When the first switch (Q1) is turned on, the control circuit (543) may be electrically connected to the connection terminal (510). The first voltage may correspond to the first voltage (V1) of FIG. 4, and the second voltage may correspond to the second voltage (V2) of FIG. 4, but is not limited thereto. For example, the first voltage and / or the second voltage described in FIG. 5 may be different from the first voltage (V1) and / or the second voltage of FIG. 4, respectively.
[0077] According to one embodiment, when the magnitude of the voltage applied through the transmission line (520) from the external electronic device (503) connected to the connection terminal (510) is greater than or equal to the first voltage and less than or equal to the second voltage, the control circuit (543) may be electrically connected to the connection terminal (510) and activated. According to one embodiment, when the control circuit (543) is activated, the control circuit (543) may receive authentication information from the external electronic device (503) through the transmission line (520). The control circuit (543) may determine whether the received authentication information is valid. For example, the operation of the control circuit (543) receiving authentication information and the operation of determining whether the received authentication information is valid may be referred to by operations 340 and 350 of FIG. 3.
[0078] According to one embodiment, if the control circuit (543) determines that the received authentication information is valid, it may transmit identification information of the electronic device (501) to the external electronic device (503). According to one embodiment, if the received authentication information is valid, the control circuit (543) may transmit identification information of the electronic device (501) stored in a second memory (not shown) (e.g., the second memory (165) of FIG. 1, the second memory (445) of FIG. 4) to the external electronic device (503). For example, the control circuit (543) may transmit identification information of the electronic device (501) in a PLC manner by using the PLC circuit (545).
[0079] FIG. 6 is a drawing illustrating pins of a USB C type connection terminal according to one embodiment.
[0080] When the electronic device (e.g., the electronic device (101) of FIG. 1) is a USB C type device, the connection terminal (e.g., the connection terminal (110) of FIG. 1) may include a GND pin (A1), a TX1+ pin (A2), a TX1- pin (A3), a VBUS pin (A4), a CC1 pin (A5), a D+ (A6), a D- (A7), an SBU1 (A8), a VBUS (A9), an RX2- (A10), an RX2+ (A11), a GND (A12), a GND pin (B1), a TX2+ pin (B2), a TX2- pin (B3), a VBUS pin (B4), a CC2 pin (B5), a D+ pin (B6), a D- pin (B7), an SBU2 pin (B8), a VBUS pin (B9), an RX1- pin (B10), an RX1+ pin (B11), and a GND pin (B12). Due to reversibility, the pins can be arranged in a mirrored configuration. This structure allows the interface (or connector) of the electronic device (101) to be mounted 180 degrees to the interface of an external electronic device (e.g., the external electronic device (103) of FIG. 1). In this case, symmetrical pins may not be used together. For example, if TX1+ and TX1- are used, TX2+, TX2-, RX2+, RX2- may not be used, and if RX1+, RX1- are used, RX2+, RX2-, TX2+, TX2- may not be used. For example, although the contact board has a total of 24 pins (e.g., 12 on the top surface and 12 on the bottom surface), the corresponding pins may not be used simultaneously. Which pins are used can be determined by the cable being connected, the connector attached to the end of the cable, and the connector connection status of the device connected to said connector.
[0081] In one embodiment, the VBUS pins (A4, B4) may represent a voltage bus. For example, the VBUS pins may be used to supply power and may be used to charge or power a device connected to a USB C type connector. The CC (configuration channel) pins (e.g., CC1 (A5), CC2 (B5)) may be used to identify the configuration and status of the connector and may also be used for communication. Based on the identified result, the electronic device (101) (or the external electronic device (103)) may operate in a downstream facing port (DFP) mode or an upstream facing port (UFP) mode. For example, the DFP mode may refer to a mode for providing data, and the UFP mode may refer to a mode for receiving data. The GND pins (A1, B1) may refer to a ground used as a reference point for voltage. For example, the GND pins (A1, B1) may be used as a return path for current. The D+ pins (A6, B6) can represent the positive polarity of the data lines. For example, the D+ pins (A6, B6) can be used to transmit positive polarity of data. The D- pins (A7, B7) can represent the negative polarity of the data lines. For example, the D- pins (A7, B7) can be used to transmit negative polarity of data. The SBU pins (e.g., SBU1 (A8), SBU2 (B8)) can be used for additional sideband data transmission. The TX pins (e.g., TX1+ (A2), TX1- (A3), TX2+ (B2), TX2- (B3)) and RX pins (e.g., RX1+ (B11), RX1- (B10), RX2+ (A11), RX2- (A10)) can be used for data transmission and reception.
[0082] According to one embodiment, the electronic device (101) may use a 1-wire communication method. The electronic device (101) may transmit identification information of the electronic device (101) to an external electronic device (103) through the 1-wire communication method. For example, the 1-wire communication may include power line communication (PLC). According to one embodiment, when the electronic device is a device including a USB C type connection terminal, the electronic device (101) may transmit identification information to the external electronic device (103) using a VBUS pin line (e.g., transmission line (120) of FIG. 1). For example, when the electronic device (101) is connected to a dedicated host device (e.g., an external electronic device (103)) for obtaining identification information of the electronic device (101) through a VBUS pin, the electronic device (101) may obtain a voltage within a first preset range from the dedicated host device through the VBUS pin line. When the electronic device (101) obtains a voltage within a preset first range, it can transmit identification information of the electronic device (101) to a dedicated host device through the VUBS pin line.
[0083] In the present disclosure, the transmission line (120) for transmitting identification information to a dedicated host device is not limited to a VBUS pin line. For example, the electronic device (101) may be connected to any one pin (e.g., CC pin, SBU pin, etc.) of a pin of a USB C type connection terminal and a dedicated host device for obtaining identification information of the electronic device (101). The electronic device (101) may perform 1-wire communication through any one of the connected pins. The electronic device (101) may transmit identification information of the electronic device (101) to the dedicated host device through any one of the connected pins.
[0084] FIG. 7 is a circuit diagram for transmitting identification information from an electronic device to an external electronic device, according to one embodiment. In the following, any description that overlaps with the description of FIG. 4 may be omitted or briefly described.
[0085] According to one embodiment, an electronic device (701) (e.g., the electronic device (101) of FIG. 1) may be connected to an external electronic device (703) (e.g., the external electronic device (103) of FIG. 1) via a connection terminal (710) (e.g., the connection terminal (110) of FIG. 1). According to one embodiment, the electronic device (701) may include a connection terminal (710), a power management circuit (730) (e.g., the power management circuit (130) of FIG. 1), and an identification information transmission circuit (740) (e.g., the identification information transmission circuit (160) of FIG. 1). The identification information transmission circuit (740) may include a switching circuit (741) (e.g., the switching circuit (161) of FIG. 1), a control circuit (743) (e.g., the control circuit (163) of FIG. 1), and a second memory (745) (e.g., the second memory (165) of FIG. 2). The external electronic device The device (703) may be electrically connected to components of the electronic device (701) (e.g., a connection terminal (710), a power management circuit (730), an identification information transmission circuit (740)) via a first transmission line (720) (e.g., a transmission line (120) of FIG. 1) and / or a second transmission line (721) (e.g., a transmission line (120) of FIG. 1).
[0086] According to one embodiment, the connection terminal (710) can receive voltage from an external electronic device (703) to which it is electrically connected. For example, the external electronic device (703) can include a general USB device and / or a dedicated host device for obtaining identification information of the electronic device (701). The connection terminal (710) can electrically connect a power management circuit (730) and an identification information transmission circuit (740) to the external electronic device (703).
[0087] According to one embodiment, when the external electronic device (703) is a general USB device, the electronic device (701) can transmit the applied voltage to the power management circuit (730) through the first transmission line (720) (e.g., the VBUS pin (A4, B4) line of FIG. 6). According to one embodiment, when the external electronic device (703) is a dedicated host device for obtaining identification information of the electronic device (701), the electronic device (701) can transmit the applied voltage to the power management circuit (730) and the identification information transmission circuit (740) through the second transmission line (721) different from the first transmission line (720) (e.g., the CC pin line (A5, B5) of FIG. 6).
[0088] According to one embodiment, the identification information transmission circuit (740) may be deactivated when the electronic device (701) is in a default state. For example, the identification information transmission circuit (740) may electrically disconnect the control circuit (743) and the connection terminal (710) when the electronic device (701) is in a default state. For example, the default state may include a state in which the electronic device (701) is not connected to an external electronic device (703) and / or a state in which a voltage within a preset second range is applied from the external electronic device (703).
[0089] According to one embodiment, the identification information transmission circuit (740) may be activated when the voltage applied from the external electronic device (703) through the second transmission line (721) is greater than or equal to the first voltage (V1) and the voltage applied through the first transmission line (720) is less than or equal to the second voltage (V2) (e.g., including when no voltage is applied). However, the condition for activating the identification information transmission circuit (740) is not limited to greater than or equal to the first voltage (V1) and less than or equal to the second voltage (V2). For example, the condition for activating the identification information transmission circuit (740) may include a condition for which the voltage applied from the external electronic device (703) through the second transmission line (721) is greater than the first voltage (V1). For example, the condition for activating the identification information transmission circuit (740) may include a condition for which the voltage applied through the first transmission line (720) is less than the second voltage (V2). According to one embodiment, the switching circuit (741) can electrically connect the control circuit (743) and the connection terminal (710) when a voltage applied through the second transmission line (721) from an external electronic device (703) connected to the connection terminal (710) is equal to or greater than a first voltage (V1) and there is no voltage applied through the first transmission line (720). For example, the switching circuit (741) can electrically connect the control circuit (743) and the connection terminal (710) using a switching element (S1), two comparators (A1, A2), and an AND gate element (G1) when a voltage applied through the second transmission line (721) is equal to or greater than V1 and a voltage applied through the first transmission line (720) is equal to or less than V2.
[0090] According to one embodiment, the comparator (A1) can output a signal indicating a comparison result according to the magnitude of the voltage applied to the + input terminal via the second transmission line (721). The comparator (A2) can output a signal indicating a comparison result according to the magnitude of the voltage applied to the - input terminal via the first transmission line (720). According to one embodiment, the comparator (A1) can output a high level signal when the voltage applied to the + input terminal via the second transmission line (721) is equal to or greater than the first voltage (V1), and can output a low level signal when the voltage is less than the first voltage (V1) or when no voltage is applied. For example, a high level signal can include a digital signal of 1, and a low level signal can include a digital signal of 0. The comparator (A2) can output a high-level signal when the voltage applied to the input terminal via the first transmission line (720) is equal to or lower than the second voltage (V2), and can output a low-level signal when the voltage is greater than the second voltage (V2).
[0091] According to one embodiment, the signals output through the two comparators (A1, A2) can be input to the AND gate element (G1). According to one embodiment, the switching element (S1) can be opened or closed based on the signals output through the two comparators (A1, A2) and the AND gate element (G1). For example, if the signals output through the two comparators (A1, A2) and the AND gate element (G1) correspond to a high level, the switching element (S1) can be closed. For example, if the signals output through the two comparators (A1, A2) and the AND gate element (G1) correspond to a low level, the switching element (S1) can be opened.
[0092] According to one embodiment, when the external electronic device (703) is a dedicated host device for obtaining identification information of the electronic device (701), the electronic device (701) can obtain a voltage from the external electronic device (703) through the second transmission line (721). For example, when the voltage applied from the external electronic device (703) through the second transmission line (721) is higher than the first voltage (V1) and there is no voltage applied through the first transmission line (720), the AND gate element (G1) can output a signal corresponding to a high level. In this case, the switching element (S1) can be closed.
[0093] According to one embodiment, when the external electronic device (703) is a general USB device, the electronic device (701) can obtain a voltage from the external electronic device (703) through the first transmission line (720). For example, when the voltage applied from the external electronic device (703) through the first transmission line (720) is greater than the second voltage (V2) and there is no voltage applied through the second transmission line (721), the AND gate element (G1) can output a signal corresponding to a low level. In this case, the switching element (S1) can be closed. For example, in the embodiment of FIG. 7, when a dedicated host device that applies a voltage within a preset first range is connected, the electronic device (701) can activate the identification information transmission circuit (740) even when the electronic device (701) is turned off. When a general USB device is connected to the electronic device (701), a normal voltage within the preset second range is applied, so that the switching element (S1) can be opened. When the switching element (S1) is opened, the identification information transmission circuit (740) can be deactivated.
[0094] Referring to FIG. 7, the switching circuit (741) is illustrated as including two comparators (A1, A2) and one AND gate element (G1), but is not limited thereto.

For example, the switching circuit (741) may include at least one logic circuit gate element. For example, the switching circuit (741) may include one or more AND gate elements or OR gate elements. However, the present invention is not limited thereto.
[0095] According to one embodiment, the control circuit (743) may, when activated, receive authentication information from an external electronic device (703) via the second transmission line (721). The control circuit (743) may determine whether the received authentication information is valid. For example, the operation of the control circuit (743) receiving authentication information and the operation of determining whether the received authentication information is valid may be referenced by operations 340 and 350 of FIG. 3 .
[0096] According to one embodiment, if the control circuit (743) determines that the received authentication information is valid, it can transmit identification information of the electronic device (701) to the external electronic device (703) that transmitted the authentication information. According to one embodiment, if the received authentication information is valid, the control circuit (743) can transmit identification information of the electronic device (701) stored in the second memory (745) to the external electronic device (703). For example, the control circuit (743) can read identification information of the electronic device (701) stored in the second memory (745). For example, the control circuit (743) can transmit identification information of the electronic device (701) read from the second memory (745) to the external electronic device (703) via the second transmission line (721).
[0097] In one embodiment, the first voltage (V1) and / or the second voltage (V2) of FIG. 7 are examples. For example, the first voltage (V1) and / or the second voltage (V2) of FIG. 7 may be the same as or different from the first voltage (V1) and / or the second voltage (V2) of FIG. 4.

The external electronic device (803) may be electrically connected to components of the electronic device (801) (e.g., a connection terminal (810), a power management circuit (830), a processor (840), and an identification information transmission circuit (850)) via a first transmission line (820) (e.g., a transmission line (120) of FIG. 1) and / or a second transmission line (821) (e.g., a transmission line (120) of FIG. 1).
[0100] According to one embodiment, the connection terminal (810) can receive voltage from an external electronic device (803) to which it is electrically connected. For example, the external electronic device (803) can include a general USB device and / or a dedicated host device for obtaining identification information of the electronic device (801). The connection terminal (810) can electrically connect the power management circuit (830) and the identification information transmission circuit (850) to the external electronic device (803).
[0101] According to one embodiment, when the external electronic device (803) is a general USB device, the electronic device (801) can transmit the applied voltage to the power management circuit (830) through the first transmission line (820) (e.g., the VBUS pin (A4, B4) line of FIG. 6). The power management circuit (830) can supply at least a portion of the voltage (or power, current) received by the processor (840) to the processor (840) to activate the processor (840). According to one embodiment, when the external electronic device (803) is a dedicated host device for obtaining identification information of the electronic device (801), the electronic device (801) can transmit the applied voltage to the power management circuit (830) and the identification information transmission circuit (850) through a second transmission line (821) different from the first transmission line (820) (e.g., the CC pin lines (A5, B5) of FIG. 6).
[0102] According to one embodiment, the identification information transmission circuit (850) can electrically disconnect the control circuit (853) and the connection terminal (810) in the default state. For example, the default state may include a state in which the electronic device (801) is not connected to the external electronic device (803) and / or a state in which a voltage within a preset second range is applied from the external electronic device (803). For example, the switching element (S1) may be open in the default state. For example, the switching element (S1) may be in a disconnected state that disconnects the connection terminal (810) and the control circuit (853) in the default state.
[0103] According to one embodiment, the identification information transmission circuit (850) may be activated when a voltage applied from an external electronic device (803) through the second transmission line (821) is greater than or equal to a first voltage (V1) and there is no voltage applied through the first transmission line (820). According to one embodiment, the electronic device (801) may include a circuit capable of detecting a voltage state of the transmission line (820). For example, the electronic device may include an analog-to-digital converter, and the analog-to-digital converter may detect a voltage state applied to the transmission line (820). According to one embodiment, the switching circuit (851) may electrically connect the control circuit (853) and the connection terminal (810) when a voltage applied from an external electronic device (803) connected to the connection terminal (810) through the second transmission line (821) is greater than or equal to the first voltage (V1) and there is no voltage applied through the first transmission line (820). For example, the switching circuit (851) can electrically connect the control circuit (853) and the connection terminal (810) using the switching element (S1), the comparator (A1), the B signal, and the AND gate element (G1) when the voltage applied through the second transmission line (821) is higher than the first voltage (V1) and there is no voltage applied through the first transmission line (820).
[0104] According to one embodiment, the comparator (A1) can output a signal indicating a comparison result according to the magnitude of the voltage applied through the second transmission line (821). According to one embodiment, the comparator (A1) can output a high level signal when the voltage applied through the second transmission line (821) is equal to or greater than the first voltage (V1), and can output a low level signal when the voltage is less than the first voltage (V1) or when no voltage is applied. For example, a high level signal can include a digital signal of 1, and a low level signal can include a digital signal of 0.
[0105] According to one embodiment, the B signal may correspond to a signal output from a GPIO (general purpose input output) of the power management circuit (830) and / or the processor (840) based on a voltage detected in the first transmission line (820). According to one embodiment, the B signal may be output as a low level signal from the GPIO of the power management circuit (830) and / or the processor (840) when the processor (840) is activated (e.g., when the electronic device (801) is turned on), and may be output as a high level signal from the GPIO of the power management circuit (830) and / or the processor (840) when the processor (840) is deactivated (e.g., when the electronic device (801) is turned off). According to one embodiment, the electronic device (801) can detect a voltage on a transmission line (e.g., a first transmission line (820), a second transmission line (821)) and / or a voltage supplied to the processor (840) (e.g., a voltage supplied by the power management circuit (830) to the processor (840). For example, the B signal can be output as a low-level signal if the voltage on the transmission line and / or the voltage supplied to the processor (840) corresponds to a processor driving voltage that activates the processor (840). For example, the B signal can be output as a high-level signal if the voltage on the transmission line and / or the voltage supplied to the processor does not correspond to the processor driving voltage. According to one embodiment, the B signal can be output from the processor (840). For example, the B signal can include a signal corresponding to a low level (or a high level) output from the processor (840).
[0106] According to one embodiment, the electronic device (801) may include a B element (not shown) that outputs a B signal.

[0108] According to one embodiment, when the external electronic device (803) is a dedicated host device for obtaining identification information of the electronic device (801), the electronic device (801) can obtain a voltage from the external electronic device (803) through the second transmission line (821). For example, when the electronic device (801) is turned off and the applied voltage is higher than the first voltage (V1), the switching element (S1) can be closed. For example, when the electronic device (801) is turned on, the switching element (S1) can be opened. For example, in the embodiment of FIG. 8, when the electronic device (801) is turned off and the processor (840) is inactive, the electronic device (801) can obtain a voltage within a preset first range to activate the identification information transmission circuit (850).
[0109] According to one embodiment, the switching element (S1) may be closed when the voltage applied from the external electronic device (803) is within a preset first range.
