Description

[0001] This application is a divisional application of Chinese patent application No. 201610694833.1 (“Electronic Device and Method for Wired and Wireless Charging in Electronic Device”). Technical Field

[0002] This disclosure relates to electronic devices. Specifically, this disclosure relates to electronic devices and methods for wired and wireless charging of electronic devices. Background Technology

[0003] In recent years, advancements in technology (such as information and communication technology and semiconductor technology) have enabled the widespread use and rapid dissemination of various electronic devices. Some recently developed electronic devices also provide mobile communication capabilities.

[0004] With the increasing use of various portable electronic devices, the batteries and battery charging methods that affect the performance and lifespan of these devices have attracted considerable interest. Consequently, electronic devices equipped with both wireless and wired charging devices have emerged, with a growing focus on devices capable of providing both wired and wireless charging.

[0005] Recent electronic devices typically include a charging circuit, and the electronic device is connected to a wired charging device. A power supply path originating from the wired charging device is connected to the charging circuit of the electronic device to charge its battery. When the electronic device is connected to a wireless charging device, a power supply path originating from the wireless charging device is connected to the charging circuit of the electronic device, thereby charging its battery.

[0006] Once on-the-go (OTG) functionality is implemented between electronic devices, the electronic device acting as a server can power another electronic device acting as a client to enable the client device to operate. Electronic devices can power external electronic devices, for example, when a memory is connected to an external connector of the electronic device to move data, or when a keyboard is connected so that the electronic device can perform the function of receiving data input from it. However, the electronic device powers the client electronic device using a path that includes charging circuitry to enable the client electronic device to perform OTG functionality; this path is the reverse of the path used to charge the electronic device's battery. Therefore, it is not yet possible to charge the battery or power external devices via the battery while performing OTG functionality. For example, when a USB memory is connected to an OTG connection unit, the electronic device powers the USB memory through the OTG connection unit to transfer data, thus limiting the ability to receive external power through the OTG connection unit. Similarly, when a keyboard is connected to an OTG connection unit, the electronic device powers the keyboard through the OTG connection unit to receive data input from it, thus preventing the ability to receive external power through the OTG connection unit.

[0007] The charging circuit of electronic devices in related fields can be configured to receive charging current from wired or wireless charging devices to charge the battery, but the electronic device cannot provide power from the battery to the wired or wireless charging device.

[0008] Various embodiments of this disclosure provide electronic devices and methods for wired and wireless charging of the electronic devices, wherein the electronic devices can receive power from external wired or wireless charging devices to charge a battery, and can provide power from the battery to external wired or wireless charging devices.

[0009] Furthermore, various embodiments of this disclosure provide electronic devices and methods for wired and wireless charging of the electronic devices, wherein the electronic devices can provide battery power to external wireless devices while performing OTG functions.

[0010] The above information is provided as background information only to aid in understanding this disclosure. It does not constitute an assertion or admission that any of the above content can be applied to the prior art of this disclosure. Summary of the Invention

[0038] The following description, with reference to the accompanying drawings, is provided to aid in a comprehensive understanding of the embodiments of this disclosure as defined by the claims and their equivalents. Various specific details are included in the following description to aid understanding, but these details should be considered merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of this disclosure. Furthermore, for clarity and brevity, descriptions of known functions and structures may be omitted.

[0039] The terms and words used in the following description and claims are not limited to their literal meaning, but are merely used by the inventors to achieve a clear and consistent understanding of this disclosure. Therefore, it will be apparent to those skilled in the art that the following description of various embodiments of this disclosure is for illustrative purposes only and is not intended to limit the disclosure as defined by the appended claims and their equivalents.

[0040] It should be understood that, unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “the” include plural indicators. Thus, for example, a reference to “component surface” includes a reference to one or more such surfaces.

[0041] As used herein, the terms “have,” “may have,” “include,” or “may include” indicate the presence of a feature (e.g., a number, function, operation, or component such as a part) without excluding the presence of other features.

[0042] In this document, the terms “A or B”, “at least one of A and / or B”, or “one or more of A and / or B” can include all possible combinations of A and B. For example, “A or B”, “at least one of A and B”, or “at least one of A or B” may refer to all of the following cases: (1) including at least one A, (2) including at least one B, or (3) including both at least one A and at least one B.

[0043] As used herein, the terms "first" and "second" may modify various components regardless of importance and / or order, and are used to distinguish one component from another without limiting the component. For example, a first user equipment and a second user equipment may refer to user equipments that are different from each other, regardless of the importance or order of the equipment.

For example, middleware 143 can assign a priority to at least one application 147 that has access to system resources of at least one electronic device 101 (e.g., bus 110, processor 120, or memory 130). For example, by processing one or more task requests according to the priority assigned to at least one application 147, middleware 143 can perform scheduling or load balancing for the one or more task requests.

[0060] API 145 is an interface that allows application 147 to control functionality provided from kernel 141 or middleware 143. For example, API 133 may include at least one interface or function (e.g., commands) for archive control, window control, image processing, or text control.

[0061] The input / output interface 150 can be used as an interface to transmit, for example, commands or data input from a user or other external device to other components of the electronic device 101. Furthermore, the input / output interface 150 can output commands or data received from other components of the electronic device 101 to a user or other external device.

[0062] For example, communication interface 170 can establish communication between electronic device 101 and external electronic devices (e.g., first electronic device 102, second electronic device 104, or server 106). For example, communication interface 170 can be connected to network 162 via wireless or wired communication to communicate with external electronic devices.

Wired communication may include at least one of the following: for example, Universal Serial Bus (USB), High Definition Multimedia Interface (HDMI), Recommended Standard (RS)-232, and Common Old-Style Telephone Service (POTS). Network 162 may include at least one of a communication network, such as a computer network (e.g., a local area network (LAN) or a wide area network (WAN)), the Internet, or a telephone network.

[0064] Both the first and second external electronic devices 102 and 104 can be devices of the same or different types as electronic device 101. According to embodiments of this disclosure, server 106 may include a group having one or more servers. According to embodiments of this disclosure, all or some of the operations performed on electronic device 101 may be performed on another electronic device or multiple other electronic devices (e.g., electronic devices 102 and 104 or server 106). According to embodiments of this disclosure, when electronic device 101 is required to perform some functions or services automatically or on request, as an alternative or additional way to perform those functions or services itself, electronic device 101 may request another device (e.g., external electronic devices 102 and 104 or server 106) to perform at least some of its associated functions. Other electronic devices (e.g., electronic devices 102 and 104 or server 106) may perform the requested functions or additional functions and transmit the results of the performance to electronic device 101. Electronic device 101 may provide the requested functions or services by processing the received results as is or additionally.

For example, when the 1-1 switch Q1 and the 1-2 switch Q2 are on, it is possible to input and output power to external devices connected through the wired interface 521. When the 1-1 switch Q1 and the 1-2 switch Q2 are off, it is not possible to input and output power to external devices connected through the wired interface 521. According to embodiments of this disclosure, the 1-1 switch Q1 and the 1-2 switch Q2 may be configured back-to-back, for example, arranged facing each other, thereby preventing power from flowing into the second switch 550.

[0143] The second switch 550 may include a 2-1 switch Q3 and a 2-2 switch Q4, and can control the power input and output through the wired interface 521 by using the "on" or "off" operation of the 2-1 switch Q3 and the 2-2 switch Q4. For example, when the 2-1 switch Q3 and the 2-2 switch Q4 are on, it is possible to input and output power to an external device connected through the wireless interface 525. When the 2-1 switch Q3 and the 2-2 switch Q4 are off, it is not possible to input and output power to an external device connected through the wireless interface 525. According to embodiments of this disclosure, the 2-1 switch Q3 and the 2-2 switch Q4 may be configured back-to-back, for example, arranged facing each other, thereby preventing power from flowing into the first switch 540.

[0144] The control logic circuit 560 can perform control to convert power input from at least one of the first switch 540 and the second switch 550 into a charging voltage or current suitable for charging the battery 510. The control logic circuit 560 can also control the conversion of power from the battery 510 into a charging voltage or current suitable for charging other batteries of external devices respectively connected to the first switch 540 and the second switch 550.

[0145] For example, control logic circuit 560 can convert a first power generated by the battery into a second power level higher than the first power level, or it can control switch group 562 to convert the first power into the second power. Furthermore, control logic circuit 560 can control switches 1-1 Q1 and 1-2 Q2 to send and receive a third power through wired interface 521, and can control switches 2-1 Q3 and 2-2 Q4 to send and receive a fourth power through wireless interface 525. Control logic circuit 560 can perform charging current sensing, charging cut-off, CC loop, CV loop, current termination loop, recharge loop, and Bat to SysFET loop functions.

[0146] Switch group 562 may include multiple switches. Switch group 562 may provide charge current (CC) to a system (e.g., a system for powering each module of an electronic device). Switch group 428 may boost or decrease the voltage of battery 410 to supply CC to connected external devices, or may boost or decrease the supplied charging voltage to supply a constant charging current to battery 410. According to embodiments of this disclosure, switch group 428 may include a buck / boost converter.

[0147] According to embodiments of this disclosure, when charging power is supplied to battery 510 from an external device (e.g., a TA), switch assembly 562 can increase or decrease the charging voltage based on a CC range and a CV range. According to embodiments of this disclosure, the CC range can be the range of charging voltages supplied to battery 510 with a CC value. The CV range can be the range of charging voltages supplied to battery 510 with a CV value.

[0148] According to embodiments of this disclosure, switch assembly 562 can perform buck converter operation within the CC range. For example, switch assembly 562 can perform buck converter operation where the charging current can be fixed at a predetermined current level (e.g., 3A) and charged within a predetermined range (3.4V to 4.4V) as the voltage of battery 510 increases. Herein, switch assembly 562 can perform operations to convert a voltage input from an external device to a voltage suitable for battery 510. For example, when the voltage of battery 510 is 3V, switch assembly 562 can supply 9W (9W = 3V × 3A) of power from an external device to battery 510, and when the voltage of battery 510 is 4V, switch assembly 562 can supply 12W (12W = 4V × 3A) of power from an external device to battery 510, so that the charging current from the external device is uniformly supplied to battery 510.

[0149] According to embodiments of this disclosure, switch group 562 can perform buck converter operation within a voltage-to-current (CV) range. For example, switch group 562 can enter the CV range, use a buffered voltage to fix the charging voltage, and gradually reduce the current to perform charging, since charging is unnecessary when the voltage of battery 510 reaches the buffered voltage (e.g., 4.4V) range. Herein, switch group 562 can perform operations to convert a voltage (e.g., 5V) input from an external device to a voltage suitable for the buffered voltage (e.g., 4.4V) of battery 510.

[0150] According to embodiments of this disclosure, when power from battery 501 is supplied to an external device, switch group 562 can perform boost converter operation. For example, when power from battery 510 is supplied to an OTG device connected to an electronic device, switch group 562 can perform an operation to convert the voltage of battery 510 (e.g., 3.4V to 4.4V) into a voltage suitable for the OTG device (e.g., 5V).

[0151] The charging switch 564 can detect the amount of charging current and can block the charging of the battery 410 in case of overcharging or overheating.

[0152] See Figure 5B , Figure 5B This is a view illustrating the operation of the charging circuit 530 when a wired power supply device is connected to the wired interface 521. When the wired power supply device is connected to the wired interface 521, the control logic circuit 560 can control the 1-1 switch Q1 and the 1-2 switch Q2 to the "on" state. The control logic circuit 560 can receive a third power through the wired interface 521. The control logic circuit 560 can control the switch group 562 to input the third power as a second power. The control logic circuit 560 can control the switch group 562 to step down the voltage of the second power to the voltage of the first power. The converted first power can be supplied to the battery 510 through the charging switch 564 for charging the battery 510. According to an embodiment of this disclosure, when the voltage of the second power is stepped down to the voltage of the first power, the switch group 562 can perform a buck converter operation, wherein the charging current can be fixed at a predetermined current level (e.g., 3A) and charged within a CC range (3.4V to 4.4V) as the voltage of the battery 510 increases. Specifically, when the voltage of battery 510 is 3V, switch assembly 562 can supply 9W (9W = 3V × 3A) of power to battery 510 from the wired power supply device, and when the voltage of battery 510 is 4V, switch assembly 562 can supply 12W (12W = 4V × 3A) of power to battery 510 from the wired power supply device, so that the charging current from the wired power supply device is evenly supplied to battery 510. Furthermore, switch assembly 562 can enter the CV range, use a buffer voltage to fix the charging voltage, and gradually reduce the current to perform charging, because charging is unnecessary when the voltage of battery 510 reaches the buffer voltage (e.g., 4.4V). In this document, switch assembly 562 can perform operations to convert the voltage input from an external device to a voltage suitable for battery 510.

[0153] See Figure 5C , Figure 5CThis is a view illustrating the operation of the charging circuit 530 when an OTG device is connected to the wired interface 521. When the OTG device is connected to the wired interface 521, the control logic circuit 560 can control the switch group 562 to boost the voltage of the first power source from the battery 510 (which is provided via the charging switch 564) to the voltage of the second power source. Here, the switch group 562 can perform boost converter operation. For example, the switch group 562 can perform operation to convert the voltage of the battery 510 (e.g., 3.4V to 4.4V) into a voltage suitable for the OTG device (e.g., 5V). Furthermore, the control logic circuit 560 can control switches 1-1 Q1 and 1-2 Q2 to be in the ON state so that the second power source is sent to the OTG device via the wired interface 521 as a third power source.

[0154] See Figure 5D , Figure 5D This is a view illustrating the operation of the charging circuit 530 when the wireless power supply device is connected to the wireless interface 525. When the wireless power supply device is connected to the wireless interface 525, the control logic circuit 560 can control switches 2-1 Q3 and 2-2 Q4 to be in the ON state, so that a fourth power is received from the wireless power supply device through the wireless interface 525. Furthermore, the control logic circuit 560 can perform control to input the fourth power to the switch group 562, and the control logic circuit 560 can control the switch group 562 to step down the voltage of the second power to the voltage of the first power.

[0155] According to embodiments of this disclosure, when the voltage of the second power source is stepped down to the voltage of the first power source, the switch assembly 562 can perform buck converter operation, wherein the charging current can be fixed at a predetermined current level (e.g., 3A) within the CC range, and the voltage of the battery 510 increases to a predetermined value (3.4V to 4.4V) within this CC range. Specifically, when the voltage of the battery 510 is 3V, the switch assembly 562 can supply 9W (9W = 3V × 3A) of power to the battery 510 from the wireless power supply device, and when the voltage of the battery 510 is 4V, the switch assembly 562 can supply 12W (12W = 4V × 3A) of power to the battery 510 from the wireless power supply device, so that the charging current from the wireless power supply device is uniformly supplied to the battery 510.

[0156] Furthermore, switch group 562 can enter the CV range, use a buffered voltage to fix the charging voltage, and gradually reduce the current to perform charging, because charging is unnecessary when the voltage of battery 510 reaches the buffered voltage (e.g., 4.4V) range. In this document, switch group 562 can perform operations to convert a voltage (e.g., 5V) input from the wireless power supply device to a voltage suitable for the buffered voltage (e.g., 4.4V). Initial power can be supplied to battery 510 via charging switch 564 and used to charge battery 510.

[0157] According to embodiments of this disclosure, an electronic device can determine whether a wireless power supply device supports fast charging by communicating with it. According to embodiments of this disclosure, the electronic device can receive identification information from the wireless power supply device and determine whether the wireless power supply device supports fast charging based on the identification information. The operation of receiving identification information can be performed by the wireless power supply device and one of an in-band communication channel and an out-of-band communication channel. An in-band communication method means that the electronic device communicates with the wireless power supply device at the same frequency used in wireless power transmission. An out-of-band communication method means that the electronic device communicates with the wireless power supply device at a different frequency than the frequency used in wireless power transmission. According to embodiments of this disclosure, the out-of-band communication method may include short-range communication protocols (e.g., BitTorrent, WiFi, NFC, etc.). According to embodiments of this disclosure, the electronic device can use in-band or out-of-band communication to determine whether the wireless power supply device supports fast charging.

[0158] See Figure 5E , Figure 5EThis is a view illustrating the operation of the charging circuit 530 when an OTG device is connected to wired interface 521 and a wireless power supply device is connected to wireless interface 525. When the OTG device is connected to wired interface 521 and the wireless power supply device is connected to wireless interface 525, control logic circuit 560 can control switch group 562 to boost the voltage of the first power source from battery 510 to the voltage of the second power source. Control logic circuit 560 can control switches 1-1 Q1 and 1-2 Q2 to be on, thereby sending a third power source to the OTG device, while simultaneously controlling switches 2-1 Q3 and 2-2 Q4 to be on to receive a fourth power source. Control logic circuit 560 can control switch group 562 to step down the voltage of the second power source corresponding to the fourth power source to the voltage of the first power source, so that the first power source can charge battery 510. According to embodiments of this disclosure, when the voltage of a first power source from battery 510 is boosted to the voltage of a second power source, switch group 562 can perform operations to convert the voltage of battery 510 (e.g., 3.4V to 4.4V) to a voltage suitable for an OTG device (e.g., 5V). According to embodiments of this disclosure, when the voltage of a second power source corresponding to a fourth power source is bucked to the voltage of the first power source, switch group 562 can perform buck converter operation, wherein the charging current can be fixed at a predetermined current value (e.g., 3A), and charging is performed within a predetermined range (e.g., 3.4V to 4.4V) from the voltage (voltage of battery 510) in the CC range. Specifically, when the voltage of battery 510 is 3V, switch assembly 562 can supply 9W (9W = 3V × 3A) of power from the wireless power supply device to battery 510, and when the voltage of battery 510 is 4V, switch assembly 562 can supply 12W (12W = 4V × 3A) of power from the wireless power supply device to battery 510, so that the charging current from the wireless power supply device is evenly supplied to battery 510. Furthermore, switch assembly 562 can enter the CV range, use a buffer voltage to fix the charging voltage, and gradually reduce the current to perform charging, because charging is unnecessary when the voltage of battery 510 reaches the buffer voltage (e.g., 4.4V). In this document, switch assembly 562 can perform operations to convert the voltage input from the wireless power supply device to a voltage suitable for battery 510.

[0159] According to embodiments of this disclosure, when the fourth power received from the wireless power supply device via the wireless interface 525 is greater than the third power transmitted to the OTG device via the wired interface 521, the control logic circuit 560 can use the fourth power to supply the third power to the OTG device. The control logic circuit 560 can also control the input of remaining power to the switch assembly 562, thereby providing remaining power to the battery 510. Furthermore, when the fourth power received from the wireless power supply device via the wireless interface 525 is less than the third power transmitted to the OTG device via the wired interface 521, the control logic circuit 560 can use the fourth power to supply power to the OTG device. The control logic circuit 560 can also control the supplementation of the OTG device using power supplied by the battery 510 and the switch assembly 562.

[0189] Reference Figure 7In operation 702, the electronic device can determine whether a wired power supply device is connected. According to embodiments of this disclosure, the electronic device can determine whether an external device connected via interface controller 529 is a wired power supply device and whether the connected external device supports fast charging. When the electronic device supports fast charging, it can communicate with the wired power supply device to change the current or voltage of the power transmitted from the wired power supply device as needed. For example, the electronic device can communicate with the wired power supply device to change the current or voltage of the power transmitted from the wired power supply device to the most efficient voltage and current among 5V and 2A, 9V and 1.67A, and 12V and 1.25A. According to embodiments of this disclosure, a predetermined protocol can be used for communication between the electronic device and the wired power supply device. For example, the predetermined protocol can be a protocol using the D+ and D- pins of the wired interface. The predetermined protocol can be a packet method protocol. According to embodiments of the present invention, the wired power supply device can essentially use 5V to begin power transmission. The 5V can be configured to be changed to an appropriate charging voltage (e.g., the most efficient fast charging voltage among 5V, 9V, and 12V) via communication between the internal control IC of the wired power supply device and the internal control IC of the electronic device using D+ and D- pins. The charging voltage is not limited to the foregoing embodiments herein. Once the charging voltage is configured, the input current limit value corresponding to the charging voltage can be set to protect the wired power supply device in the event of failure of the internal overcurrent protection (OCP) IC. In this document, the wired power supply device can first control the voltage and current supplied to the electronic device for charging according to the input current limit value corresponding to the charging voltage, and then control the voltage and current for charging via communication with the electronic device.

According to an embodiment of this disclosure, when the electronic device is connected to the OTG pin of the wired interface 421, the electronic device can determine that the OTG device 403 is connected to it via the interface controller 529.

[0196] Once the connection to the OTG device 403 is confirmed, in operation 804, the electronic device can turn on switch 1-1 Q1 and switch 1-2 Q2, thereby enabling power to be sent to the OTG device.

[0197] The electronic device turns on switch 1-1 Q1 and switch 1-2 Q2. Then, in operation 806, the on / off operation of switch QH and switch QL is controlled to cause switch group 562 to perform a boost operation. Depending on the boost operation, switch group 562 can perform the on / off operation of switch QH and switch QL respectively, and can boost the voltage from battery 510 to provide CC to the OTG device. For example, switch group 562 can perform an operation to convert the voltage of battery 510 (e.g., 3.4V to 4.4V) to a voltage suitable for the OTG device (e.g., 5V).

[0198] In operation 808, the electronic device can control the QH and QL switches of the switch group 562 and the QF switch of the charging switch 564 to supply power from the battery 510 to the OTG device, enabling the execution of OTG functions. For example, the electronic device can operate the QF switch so that the voltage from the battery 501 is passed to the QH and QL switches for boosting.

[0199] Figure 9 This is a view illustrating the operation of an electronic device when a wireless power supply device is connected, according to an embodiment of the present disclosure.

[0200] Reference Figure 9 In operation 902, the electronic device can determine whether a wireless power supply device is connected. According to embodiments of this disclosure, the electronic device can determine that a wireless power supply device is connected when power reception is detected at the TRX IC via a conductive pattern of the wireless interface.

[0201] Once the wireless power supply is confirmed to be connected, in operation 904, the electronic device can turn on switch 2-1 Q3 and switch 2-2 Q4, thereby enabling it to receive power from the wireless power supply.

[0202] The electronic device turns on switches 2-1 (Q3) and 2-2 (Q4). Then, in operation 906, the on / off operations of switches QH and QL are controlled to cause switch group 562 to perform a step-down operation. Based on the step-down operation, switch group 562 can perform the on / off operations of switches QH and QL respectively, and can step down the charging voltage from the wired power supply equipment to provide a constant charging current to battery 510.

[0203] According to embodiments of this disclosure, when the charging voltage from the wireless power supply device is stepped down, the switch group 562 can perform buck converter operation, wherein the charging current can be fixed at a predetermined current level (e.g., 3A) and charging is performed within a CC range where the voltage of the battery 510 increases to a predetermined range (e.g., 3.4V to 4.4V). Specifically, when the voltage of the battery 510 is 3V, the switch group 562 can supply 9W (9W = 3V × 3A) of power from the wired power supply device to the battery 510, and when the voltage of the battery 510 is 4V, the switch group 562 can supply 12W (12W = 4V × 3A) of power from the wired power supply device to the battery 510, so that the charging current from the wired power supply device is uniformly supplied to the battery 510. Furthermore, the switch group 562 can enter the CV range, use a buffer voltage to fix the charging voltage, and gradually reduce the current to perform charging, because charging is unnecessary when the voltage of the battery 510 reaches the buffer voltage (e.g., 4.4V). In this document, switch group 562 can perform operations to convert the voltage input from the wireless power supply device into a voltage suitable for battery 510.

[0204] In operation 908, the electronic device can control the QH switch, the QL switch, and the QF switch of the charging switch 564 to supply charging current from the wireless power supply device to the battery 510. For example, the electronic device can operate the QF switch to supply a stepped-down charging current to the battery based on the on / off operation of the QH switch and the QL switch.

[0205] Figure 10 This is a view illustrating the operation of an electronic device when a wireless power supply device and an OTG device are connected, according to an embodiment of the present disclosure.

[0206] Reference Figure 10 In operation 1002, the electronic device can determine whether a wireless power supply device and an OTG device are connected. The wireless power supply device can be connected via wireless interface 525, and the OTG device can be connected via wired interface 521. According to embodiments of this disclosure, when the TRX IC operates via the conductive pattern of the wireless interface, the electronic device can determine that a wireless power supply device is connected. Furthermore, when the electronic device connects to the OTG pin of the wireless interface, the electronic device can determine that an OTG device is connected.

[0207] Once it is confirmed that the wireless power supply and the OTG device are connected to the electronic device, in operation 1004, the electronic device can turn on switch 1-1 Q1, switch 1-2 Q2, switch 2-1 Q3 and switch 2-2 Q4 to enable it to receive power from the wireless power supply and to input / output through the OTG device.

[0208] The electronic device turns on switches Q1 (1-1), Q2 (1-2), Q3 (2-1), and Q4 (2-2). Then, in operation 1006, the on / off operation of switches QH and QL can be controlled to cause switch group 562 to perform buck or boost operation. According to the buck operation, switch group 562 can perform the on / off operation of switches QH and QL respectively, and can step down the charging voltage from the wireless power supply device to provide a constant charging current to battery 510. Furthermore, according to the boost operation, switch group 562 can perform the on / off operation of switches QH and QL respectively to provide a constant current (CC) to the OTG device. According to embodiments of this disclosure, when the voltage of the power from battery 510 is boosted, switch group 562 can perform operations to convert the voltage of battery 510 (e.g., 3.4V to 4.4V) to a voltage suitable for the OTG device (e.g., 5V). According to embodiments of this disclosure, when the charging voltage from the wireless power supply device is stepped down, the switch group 562 can perform buck converter operation, wherein the charging current can be fixed at a predetermined current level (e.g., 3A), and charging is performed within a CC range where the voltage of the battery 510 increases to a predetermined range (e.g., 3.4V to 4.4V). Specifically, when the voltage of the battery 510 is 3V, the switch group 562 can supply 9W (9W = 3V × 3A) of power from the wireless power supply device to the battery 510, and when the voltage of the battery 510 is 4V, the switch group 562 can supply 12W (12W = 4V × 3A) of power from the wireless power supply device to the battery 510, so that the charging current from the wireless power supply device is uniformly supplied to the battery 510. Furthermore, the switch group 562 can enter the CV range, use a buffer voltage to fix the charging voltage, and gradually reduce the current to perform charging, because charging is unnecessary when the voltage of the battery 510 reaches the buffer voltage (e.g., 4.4V). In this document, switch group 562 is operable to convert the voltage input from the wireless power supply device into a voltage suitable for battery 510.

[0209] In operation 1008, the electronic device can control the on / off operation of the QH switch, QL switch, and QF switch of the charging switch 564, so that the switch group 562 performs a step-down operation to supply power from the battery 510 to the OTG device. Thus, the OTG function is performed while providing charging current from the wireless power supply device to the battery 510. For example, the electronic device can operate the QF switch to provide a stepped-down charging current to the battery according to the on / off operation of the QH and QL switches, or it can operate the QF switch to supply power to the QH and QL switches, thereby performing the operation of converting the output voltage from the battery 510 into a voltage suitable for the OTG device.

[0210] According to embodiments of this disclosure, an OTG device can be connected via a wired interface 521 while receiving charging power from a wireless power supply device via a wireless interface 525, or the wireless power supply device can be connected while simultaneously sending charging power to the OTG device. According to embodiments of this disclosure, when the charging power received from the wireless power supply device via the wireless interface 525 is greater than the charging power sent to the OTG device via the wired interface 521, the electronic device can use the received charging current to supply charging current to the OTG device and input residual current to the battery 510 to charge the battery 510. Furthermore, when the charging power received from the wireless power supply device via the wireless interface 525 is less than the charging power sent to the OTG device via the wired interface 521, the electronic device can use the received charging current to supply power to the OTG device and use the charging current from the battery 510 to supplement the insufficient power to the OTG device.

[0212] Reference Figure 11 In operation 1102, the electronic device can determine whether a wireless power receiving device is connected. Based on the reception of a wireless power request signal, when the TRX IC operates through the conductive pattern of the wireless interface, the electronic device can determine that a wireless power receiving device is connected.

[0213] Once the wireless power supply is confirmed to be connected, in operation 904, the electronic device can turn on switch 2-1 Q3 and switch 2-2 Q4, thereby enabling it to receive power from the wireless power supply.

[0214] The electronic device turns on switches 2-1 (Q3) and 2-2 (Q4). Then, in operation 1106, the on / off operations of switches QH and QL are controlled to cause switch group 562 to perform a boost operation. According to the boost operation, switch group 562 can perform the on / off operations of switches QH and QL respectively, and can boost the voltage from battery 510 to provide a constant charging current to the wireless power receiving device. According to embodiments of this disclosure, when power from battery 510 is supplied to the wireless power receiving device, switch group 562 can perform operations to convert the voltage of battery 510 (e.g., 3, 4V to 4.4V) into a voltage suitable for the wireless power receiving device.

[0215] In operation 1108, the electronic device can control the QH switch, the QL switch, and the QF switch of the charging switch 564 to supply power from the battery 510 to the wireless power receiving device. For example, the electronic device can operate the QF switch to supply power to the QH switch and the QL switch to perform an operation that changes the output voltage from the battery 510 to a voltage suitable for the wireless power receiving device.

[0216] Figure 12 This is a view illustrating the operation of an electronic device when a wireless power supply device and a wireless power receiving device are connected, according to an embodiment of the present disclosure.

[0217] Reference Figure 12 In operation 1202, the electronic device can determine whether a wireless power supply device and a wireless power receiving device are connected. The wireless power receiving device can be connected via wireless interface 525, and the wired power supply device can be connected via wired interface 521.

[0218] Once the wired power supply and wireless power receiving devices are connected, in operation 1204, the electronic device can turn on switch 2-1 Q3 and switch 2-2 Q4, thereby enabling power to be received from the wired power supply and making power supply to the wireless power receiving device available.

[0219] The electronic device turns on switches 1-1 (Q1), 1-2 (Q2), 2-1 (Q3), and 2-2 (Q4). Then, in operation 1206, the on / off operations of switches QH and QL can be controlled to cause switch group 562 to perform a step-down operation. According to the step-down operation, switch group 562 can respectively perform the on / off operations of switches QH and QL, and can step down the charging voltage from the wired power supply to provide a constant charging current to battery 510. According to embodiments of this disclosure, when the charging voltage from the wired power supply is stepped down, switch group 562 can perform a step-down converter operation, wherein the charging current is fixed at a predetermined current level (e.g., 3A), and charging is performed within a predetermined range (e.g., 3.4V to 4.4V) from the CC range (battery 510). Specifically, when the voltage of battery 510 is 3V, switch assembly 562 can supply 9W (9W = 3V × 3A) of power from the wired power supply to battery 510, and when the voltage of battery 510 is 4V, switch assembly 562 can supply 12W (12W = 4V × 3A) of power from the wired power supply to battery 510, so that the charging current from the wired power supply is evenly supplied to battery 510. Furthermore, switch assembly 562 can enter the CV range, use a buffer voltage to fix the charging voltage, and gradually reduce the current to perform charging, because charging is unnecessary when the voltage of battery 510 reaches the buffer voltage (e.g., 4.4V). In this document, switch assembly 562 can perform operations to convert the voltage input from the wired power supply to a voltage suitable for battery 510. According to embodiments of this disclosure, when a first power level from battery 510 is boosted to a second power level, switch group 562 can perform operations to convert the voltage of battery 510 (e.g., 3.4V to 4.4V) into a voltage suitable for a wireless power receiving device (e.g., 5V).

[0220] In operation 1208, the electronic device can control the QH switch, QL switch, and QF switch of the charging switch 564 to provide charging current from the wired power supply device to the battery 501 and simultaneously provide charging current to the wireless power receiving device.

[0221] For example, an electronic device can operate a QF switch to provide a stepped-down charging current to the battery corresponding to the stepped-down voltage based on the on / off operation of the QH and QL switches, or it can control the QH and QL switches and the QF switch of the charging switch 564 to provide charging current from a wired power supply device to a wireless power receiving device.

[0222] According to embodiments of this disclosure, when an electronic device supplies charging current to a wireless power receiving device while simultaneously receiving current from a wired power supply device, the electronic device can control the on / off operation of switches 2-1 (Q3), 2-2 (Q4), QH, and QL to use the remaining current to charge battery 510 after supplying charging current to the wireless power receiving device using the charging current received from the wired power supply device. When the charging current received from the wired power supply device is HV (e.g., more than 5V) and the wireless power receiving device does not receive HV, the electronic device changes the charging voltage received from the wired power supply device to 5V and uses the changed charging voltage to supply power to battery 510. The electronic device can control the on / off operation of switches 2-1 (Q3), 2-2 (Q4), QH, and QL to ensure that the remaining power is charged to battery 510.

[0226] The electronic device connects switches 1-1 (Q1), 1-2 (Q2), 2-1 (Q3), and 2-2 (Q4). Then, in operation 1306, the electronic device can control the on / off operation of switches QH and QL to cause switch group 562 to perform a boost operation. According to the boost operation, switch group 562 can perform the on / off operation of switches QH and QL respectively, and can boost the voltage from battery 510 to power the OTG device and the wireless power receiving device. According to embodiments of this disclosure, when the voltage of the power from battery 510 is boosted, switch group 562 can perform operations to convert the voltage of battery 510 (e.g., 3.4V to 4.4V) to a voltage suitable for the OTG device and the wireless power receiving device.

[0227] In operation 1308, the electronic device can control the QH switch, QL switch, and QF switch of the charging switch 564 so that a portion of the battery power is supplied to the OTG device, while another portion of the battery power is supplied to the wireless power receiving device.
