One of these communication modules can communicate with the external electronic device 104 via a first network 198 (e.g., a short-range communication network such as Bluetooth™, Wi-Fi Direct, or Infrared Data Association (IrDA)) or a second network 199 (e.g., a long-range communication network such as a traditional cellular network, 5G network, next-generation communication network, the Internet, or a computer network (e.g., a local area network (LAN) or a wide area network (WAN))). These various types of communication modules can be implemented as a single component (e.g., a single chip) or as multiple components separated from each other (e.g., multiple chips).

[0055] Figure 2 This is a perspective view showing the connector of an electronic device according to an embodiment.

[0056] According to an embodiment, electronic device 200 (e.g., Figure 1 The electronic device 101 can be implemented as a portable electronic device such as a smartphone or tablet PC, but is not limited thereto. The electronic device 200 may include a connector 210 for connecting external electronic devices (e.g., ...). Figure 1 Interface 177 or Figure 1 (Connector 178).

[0057] According to an embodiment, electronic device 200 can be connected to an external electronic device via connector 210, and can send information and / or data to / receive information and / or data (e.g., multimedia data such as audio data and / or other control commands) to and from the connected external electronic device.

[0058] According to an embodiment, when the external electronic device connected to the electronic device 200 via connector 210 is a charging device (e.g., a charger), the electronic device 200 can receive power (or voltage) from the external electronic device and can use at least a portion of the supplied power to power a battery (e.g., ...). Figure 1 Charge the battery (189).

[0059] According to an embodiment, the electronic device 200 may include an opening formed on one side (e.g., a surface) of the housing and a hole connected to the opening, and a connector 210 may be disposed in said hole. For example, as Figure 2As shown, openings and holes can be formed on the lower side of the housing of the electronic device 200, and connector 210 can be disposed therein, but this disclosure is not limited thereto. For example, connector 210 can be disposed on the other side (e.g., surface) of the housing of the electronic device 200.

[0060] Figure 3a It is a schematic perspective view including a connector for an electronic device and a connector for an external electronic device according to an embodiment of the present disclosure. Figure 3b This is a schematic diagram illustrating an example pin structure of a connector for an electronic device according to an embodiment of the present disclosure.

[0061] Reference Figure 3a The connector 320 of the external electronic device can be inserted into the connector 210 of the electronic device 200. According to the embodiment, the type of external electronic device is not limited, and may include, for example, a battery pack that supplies power to the electronic device 200, a device that communicates with the electronic device 200, or an external memory connected to the electronic device 200.

[0062] According to an embodiment, the connector 320 of the external electronic device can be accommodated through a hole provided in the electronic device 200 to physically contact the connector 210 of the electronic device 200 (e.g., connected to or attached to the connector 210 of the electronic device 200), and can be electrically connected to the electronic device 200 based on the physical contact.

[0063] According to an embodiment, the connector 210 and the hole structure of the electronic device 200 can be reversible. For example, the connector 210 can be symmetrical about a first direction perpendicular to the insertion direction of the external electronic device (e.g., from the bottom to the top of the electronic device 200) and a second direction opposite to the first direction. That is, for example, since the connector 210 can be connected in either of two orientations (e.g., forward or inverted), the connector 210 can have double rotational symmetry.

[0064] like Figure 3a As shown, one side or surface (e.g., surface A) of the connector 320 of the external electronic device can be inserted into the connector 210 of the electronic device 200 in a direction parallel to the front side or surface of the electronic device 200 (e.g., the surface where the display of the electronic device 200 is located). That is, for example, after the connector 320 is inserted into the connector 210, surface A of the connector 320 can be positioned parallel to the surface where the display of the electronic device 200 is located. Alternatively, the other side or surface (e.g., surface B) of the connector 320 of the external device can be inserted in a direction parallel to the front side or surface of the electronic device 200. That is, for example, after the connector 320 is inserted into the connector 210, surface B of the connector 320 can be positioned parallel to the surface where the display of the electronic device 200 is located.

[0065] According to an embodiment, connector 210 may include a plurality of pins (or terminals). According to an embodiment, when connector 320 of external electronics is inserted in a different orientation (e.g., inverted), each pin of connector 320 of external electronics that is electrically connected to each pin included in connector 210 of electronics 200 may be different.

[0066] According to embodiments, connector 210 and / or connector 320 may be connectors according to the USB standard. Connector 210 may be, for example, a Type-C connector conforming to the USB Type-C standard, but is not limited thereto. For example, various standard wired interfaces or non-standard wired interfaces such as High Definition Multimedia Interface (HDMI), Recommended Standard 232 (RS232), Power Line Communication, or Common Old-Style Telephone Service (POTS) may be applied to connector 210 and / or connector 320 of this disclosure.

[0088] According to an embodiment, processor 120 can adjust the open / closed state of at least one switch, causing the CC pin to change to an open state. The CC pin being in an open state can, for example, mean that the CC pin is in a high-impedance state (e.g., a state where a very high resistance value is applied), and can also mean that no electrical signal is being sent to or received from the CC pin. With the CC pin changing to a high-impedance state, the processor 412 of external electronic device 410 can stop supplying power to electronic device 101.

[0098] According to an embodiment, each port can be electrically connected to a corresponding pin and a corresponding control circuit.

The signal transmitted to the first signal path SP1 may include, for example, an electrical signal.

[0103] According to an embodiment, the first signal path SP1 may be a signal path including a first port 511 electrically connected to the first pin 501. According to an embodiment, the second signal path SP2 may be a signal path including a second port 512 electrically connected to the second pin 502.

[0104] According to an embodiment, the first signal path SP1 may include a first port 511 electrically connected to the first pin 501 and a first internal signal path portion electrically connected to the first port 511 and configured to transmit power supplied from an external electronic device through the first pin 501 to the battery 189.

[0105] According to an embodiment, the first signal path SP1 may include a first port 511 electrically connected to the first pin 501 and a first control circuit 521 electrically connected to the first port 511.

[0106] According to an embodiment, the second signal path SP2 may include a second port 512 electrically connected to the second pin 502 and a second internal signal path portion electrically connected to the second port 512 and configured to selectively connect the second port 512 and ground GND. The second internal signal path portion may correspond to, for example, the second circuit portion of the second control circuit 522 described above.

[0107] According to an embodiment, the power control circuit 500 can be configured to: disconnect the second port 512 from ground (GND) based on the presence of moisture in the interface 177, and not supply power from the external electronic device through the first pin 501, or reduce the voltage value of the power supplied through the first pin 501. For example, the second circuit portion (or the second internal signal path portion) of the second control circuit 522 can be configured to: disconnect the second port 512 from ground (GND) based on the presence of moisture in the interface 177 when the external electronic device is connected to the interface 177, and not supply power from the external electronic device through the first pin 501, or reduce the voltage value of the power supplied through the first pin 501. This voltage value can, for example, be set to be lower than (or less than) a reference voltage value.

[0108] According to an embodiment, the second circuit portion (or the second internal signal path portion) of the second control circuit 522 may include a switch disposed between the second port 512 and ground GND. The power control circuit 500 may be configured to electrically disconnect the second port 512 from ground GND based on the switch being open. For example, the power control circuit 500 may disconnect the second port 512 from ground GND by setting the switch to an open state. The power control circuit 500 may also be configured to electrically connect the second port 512 to ground GND based on the switch being closed. For example, the power control circuit 500 may connect the second port 512 to ground GND by setting the switch to a closed state. Referring below... Figure 6a and Figure 6b An example of a second control circuit 522, including a switch, is described in more detail.

[0109] Figure 6a and Figure 6b This is a circuit diagram illustrating a second control circuit included in the power control circuit of an electronic device according to an embodiment of the present disclosure.

[0110] exist Figure 6a and Figure 6b In one embodiment, the second control circuit may be Figure 5 An example of the second control circuit 522 included in the power control circuit 500. Figure 6a and Figure 6b In the embodiment, the second pin 502 may be, for example, Figure 3b The CC pin.

[0111] exist Figure 6a and Figure 6b In the embodiments described, it can be understood that the operation performed by the power control circuit 500 is in an electronic device (e.g., Figure 1 Electronic device 101 or Figure 2 The electronic device 200) or the processor of the electronic device (e.g., Figure 1 It is executed under the control of the processor 120.

[0112] Reference Figure 6a The second control circuit 522 may be electrically connected to the second port 512 and may include a switch 610 and / or a resistor 620.

[0113] According to an embodiment, switch 610 may be disposed between the second port 512 and ground GND, and configured to selectively connect the second port 512 (or the second pin 502) and ground GND. For example, switch 610 may electrically connect or disconnect the second port 512 from ground GND depending on the open / closed state of switch 610.

[0114] According to the embodiments, the switch 610 may include, for example, a bipolar junction transistor (BJT), a field-effect transistor (FET), a thyristor, a relay switch, an insulated gate bipolar transistor (IGBT), a microelectromechanical system (MEMS) switch, etc., but is not limited thereto.

[0115] According to an embodiment, the power control circuit 500 can disconnect the second port 512 from ground GND by setting the open / closed state of switch 610 to the open state. The power control circuit can also connect the second port 512 to ground GND by setting the open / closed state of switch 610 to the closed state.

[0116] According to an embodiment, the power control circuit 500 can change the open / closed state of switch 610 from a first state to a second state, thereby changing the connection state between the second port 512 and ground GND. For example, the power control circuit 500 can change the open / closed state of switch 610 from an open state to a closed state, thereby changing the connection state between the second port 512 and ground GND from an electrically disconnected state to an electrically connected state. For example, the power control circuit 500 can change the open / closed state of switch 610 from a closed state to an open state, thereby changing the connection state between the second port 512 and ground GND from an electrically connected state to an electrically disconnected state.

[0117] According to an embodiment, based on the identification of an external electronic device (e.g., Figure 4 External electronic device 410) is connected via a connector (e.g., interface 177 or Figures 2 to 3b Connector 210) is connected to an electronic device (e.g., Figure 1 The electronic device 101) and the power control circuit 500 can set the switch 610 to the closed state, so that the second port 512 is electrically connected to ground GND through the resistor 620.

[0118] According to an embodiment, resistor 620 may be disposed between switch 610 and ground GND. Second port 512 (or second pin 502) may be electrically connected to ground GND via resistor 620.

[0119] According to an embodiment, resistor 620 may be a pull-down resistor Rd of the second pin 502 (or the second port 512). Resistor 620 may be set to, for example, 5.1 kΩ.

[0120] According to an embodiment, resistor 620 can be used to enable an external electronic device connected to the electronic device via a connector to detect the connection of the electronic device.

[0121] According to an embodiment, resistor 620 can be used to conduct charging negotiation between an electronic device connected via a connector and an external electronic device. For example, resistor 620 can be used to enable the electronic device to operate as a powered device (e.g., a power consumer).

[0122] Reference Figure 6b The second control circuit 522 may further include at least one current source (e.g., a first current source 631 and / or a second current source 632), at least one switch (e.g., a first switch 641 and / or a second switch 642) connected to the at least one current source, and / or a comparator 650. Regarding Figure 6b The descriptions of switch 610 and resistor 620 can be found in [reference]. Figure 6a The description is provided, and its repeated description may be omitted here.

[0123] According to an embodiment, the first current value supplied by the first current source 631 may be different from the second current value supplied by the second current source 632. For example, the first current value supplied by the first current source 631 (e.g., 1 μA) may be less than the second current value supplied by the second current source 632 (e.g., 80 μA). In this disclosure, the first current source 631 and the second current source 632 may be collectively referred to as current sources, and the first switch 641 and the second switch 642 may be collectively referred to as switches.

[0124] According to an embodiment, switches 641 and 642 can selectively connect a corresponding current source 631 or 632 to the second port 512 (or the second pin 502). For example, the first switch 641 can electrically connect or disconnect the first current source 631 connected to the first switch 641 from the second pin 502. For example, the second switch 642 can electrically connect or disconnect the second current source 632 connected to the second switch 642 from the second pin 502.

[0125] According to the embodiments, switch 641 or 642 may be, for example, a BJT, FET, thyristor, relay switch, IGBT or MEMS switch, but is not limited thereto.

[0126] According to an embodiment, switch 610, first switch 641, and second switch 642 can be synchronized (or associated) with each other. For example, during normal operation (e.g., Figure 14In the normal state operation of operation 1410, when any one of switch 610, first switch 641, and second switch 642 is in the closed state, all other switches can be in the open state. According to an embodiment, in the normal state operation, when switch 610 is in the closed state, first switch 641 and second switch 642 can be in the open state. In this case, the CC pin can be electrically connected to ground via resistor 620. According to an embodiment, in the normal state operation, when first switch 641 is in the closed state, switch 610 and second switch 642 can be in the open state. In this case, first current source 631 can be connected to the CC pin, and a first current value of first current source 631 can be supplied to the CC pin. According to an embodiment, in the normal state operation, when second switch 642 is in the closed state, switch 610 and first switch 641 can be in the open state. In this case, second current source 632 can be connected to the CC pin, and a second current value of second current source 632 can be supplied to the CC pin. Therefore, only one component (e.g., resistor 620, first current source 631, or second current source 632) can be connected to the second pin 502 at a time.

[0127] Table 1 shows the opening / closing operations of the switch under normal conditions. The opening / closing operations of the switch in Table 1 are only examples of the opening / closing states of the switch under normal conditions, and the switch can be opened / closed in different ways.

[0128] [Table 1]

[0129]

[0130] According to the embodiment, in the normal state, the CC pin (or the second control circuit 522) can periodically repeat the pull-up and pull-down states. Therefore, in the normal state, the pull-up resistor Rp and the pull-down resistor Rd can be periodically connected to the CC pin. For example, as shown in Table 1, in the first time interval, switch 610 can be in the closed state, and the second switch 641 and the second switch 642 can operate in the open state to be in the pull-down state. In the second time interval, which is the next time interval after the first time interval, the first switch 641 can operate in the closed state, and switches 610 and 642 can operate in the open state to be in the pull-up state. In the third time interval, which is the next time interval after the second time interval, similarly to the first time interval, switch 610 can be in the closed state, and the second switch 641 and the second switch 642 can operate in the open state to be in the pull-down state. Thus, in the normal state, under the control of the switches of the power control circuit 500, the pull-up and pull-down states can be periodically repeated. According to an embodiment, when an external electronic device is connected via interface 177, the second control circuit 522 can control the operation of the third time interval to continue.

[0131] According to an embodiment, the second switch 642 can be omitted as an optional component. In this case, the operation in each time interval in Table 1 above can be described using only the operation of switch 610 and the second switch 641.

[0132] Table 2 shows the opening / closing operations of the switch under abnormal conditions (e.g., when foreign objects or moisture are detected). The opening / closing operations of the switch in Table 2 are merely examples of the opening / closing operations of the switch under abnormal conditions, and the switch may be opened / closed in another manner.

[0133] [Table 2]

[0134]

[0135] According to an embodiment, the power control circuit 500 can determine whether the CC pin is in an abnormal state when the first switch 641 is closed. For example, as shown in the fourth time interval in Table 2, the power control circuit 500 can operate the first switch 641 in the closed state and operate the switch 610 and the second switch 642 in the open state, and determine whether the CC pin is in an abnormal state based on the voltage value of the CC pin when the first switch 641 is closed.

[0136] According to an embodiment, based on the determination that the CC pin is in an abnormal state when the first switch 641 is closed, the power control circuit 500 can change the second switch 642 from an open state to a closed state, and determine whether moisture exists in the open state of the second switch 642. For example, when it is determined that the CC pin is in an abnormal state when the first switch 641 is closed (e.g., the switching state of the fourth time interval), as shown in the fifth time interval of Table 2, the power control circuit 500 can operate the second switch 642 in the closed state and operate the switches 610 and the first switch 641 in the open state, and determine whether moisture exists in the CC pin in the abnormal state based on the voltage value of the CC pin. Thus, for example, when an abnormal state is detected in the switching state of the fourth time interval, additional operations for moisture detection can be performed in the switching state of the fifth time interval. Based on the determination that moisture exists in the closed state of the second switch 642, the power control circuit 500 can set all switches 610, the first switch 641, and the second switch 642 to the open state. For example, when moisture is detected in the closed state of the second switch 642 (e.g., the switching state of the fifth time interval), as shown in the sixth time interval of Table 2, the power control circuit 500 can set all switches 610, 641, and 642 to the open state. Thus, for example, when moisture is detected in the switching state of the fifth time interval, the circuit can switch to the switching state of the sixth time interval.

[0137] According to an embodiment, based on the determination that the CC pin is in an abnormal state when the first switch 641 is closed, the power control circuit 500 can set all switches 610, 641, and 642 to the open state. For example, when it is determined that the CC pin is in an abnormal state when the first switch 641 is closed (e.g., the switch state of the fourth time interval), as shown in the sixth time interval of Table 2, the power control circuit 500 can set all switches 610, 641, and 642 to the open state. Thus, for example, when an abnormal state is detected in the switch state of the fourth time interval, the system can immediately switch to the switch state of the sixth time interval instead of operating in the switch state of the fifth time interval. According to an embodiment, after all switches 610, 641, and 642 are open, the power control circuit 500 can be configured to repeat the switch states of the fifth and sixth time intervals.

[0138] According to an embodiment, the second switch 642 can be omitted as an optional component. In this case, the operations in each time interval in Table 2 above can be described using only the operations of switch 610 and the first switch 641. For example, the switching operation of the fifth time interval between the fourth and sixth time intervals in Table 2 can be omitted.

[0139] Table 3 shows the opening / closing operations of the switches under abnormal conditions (e.g., when foreign objects or moisture are detected). The opening / closing operations of the switches in Table 3 are merely examples of the opening / closing operations of the switches under abnormal conditions, and the switches may open / close in different ways.

[0140] [Table 3]

[0141]

[0142] According to an embodiment, the power control circuit 500 can determine whether the CC pin is in an abnormal state when the first switch 641 is closed. For example, as shown in the seventh time interval in Table 3, the power control circuit 500 can operate the first switch 641 in the closed state and operate the switch 610 and the second switch 642 in the open state, and determine whether the CC pin is in an abnormal state based on the voltage value of the CC pin when the first switch 641 is closed.

[0143] According to an embodiment, based on the determination that the CC pin is in an abnormal state when the first switch 641 is closed, the power control circuit 500 can change the second switch 642 from an open state to a closed state and determine whether moisture is present. For example, when the first switch 641 is closed (e.g., the switching state of the seventh time interval), as shown in the ninth time interval of Table 3, the power control circuit 500 can operate the second switch 642 in the closed state and operate the switches 610 and the first switch 641 in the open state, and determine whether moisture is present in the CC pin in the abnormal state based on the voltage value of the CC pin. Based on the determination that moisture is present when the second switch 642 is closed, the power control circuit 500 can set all switches 610, the first switch 641, and the second switch 642 to the open state. For example, when it is determined that moisture is present when the second switch 642 is closed (e.g., the switching state of the ninth time interval), as shown in the tenth time interval of Table 3, the power control circuit 500 can set all switches 610, the first switch 641, and the second switch 642 to the open state.

[0144] According to an embodiment, based on the determination that the CC pin is in an abnormal state when the first switch 641 is closed, the power control circuit 500 can set all switches 610, 641, and 642 to the open state. For example, when it is determined that the CC pin is in an abnormal state when the first switch 641 is closed (e.g., the switch state in the seventh time interval), as shown in the eighth time interval of Table 3, the power control circuit 500 can set all switches 610, 641, and 642 to the open state. With all switches 610, 641, and 642 open, the power control circuit 500 can change the second switch 642 from the open state to the closed state and determine whether moisture is present. For example, with all switches 610, 641, and 642 open (e.g., the switch state in the eighth time interval), as shown in the ninth time interval of Table 3, the power control circuit 500 can operate the second switch 642 in the closed state and operate switches 610 and 641 in the open state, and determine whether moisture is present in the CC pin in the abnormal state based on the voltage value of the CC pin. Based on the determination that moisture exists when the second switch 642 is closed, the power control circuit 500 can set all switches 610, 641, and 642 to the open state. For example, when moisture is determined to exist when the second switch 642 is closed (e.g., the switch state of the ninth time interval), as shown in the tenth time interval of Table 3, the power control circuit 500 can set all switches 610, 641, and 642 to the open state.

[0145] According to an embodiment, the second switch 642 can be omitted as an optional component. In this case, the operations in each time interval in Table 3 above can be described using only the operations of switch 610 and the first switch 641. For example, the switching operation of the ninth time interval between the eighth and tenth time intervals in Table 3 can be omitted.

[0146] According to an embodiment, the first current source 631, the second current source 632, and / or the comparator 650 can be used to determine whether moisture is present in the second pin 502 (or the second port 512). For example, the power control circuit 500 can be configured to connect the first current source 631 to the second pin 502 via switch control (e.g., controlling the first switch 641 to be closed and the second switch 610 and the second switch 642 to be open), and use the comparator 650 to determine whether the second pin 502 is in an abnormal state based on a first voltage value (or a first resistance value of the second pin 502 corresponding to the first voltage value) obtained as the voltage value of the second pin 502 when the first current source 631 is connected to the second pin 502. The power control circuit 500 can use the comparator 650 to determine that it is in an abnormal state, for example, when the first voltage value (or the first resistance value) is within a specified first range, and to determine that it is not in an abnormal state when the first voltage value (or the first resistance value) is not within the specified first range. For example, based on determining that the second pin 502 is in an abnormal state, the power control circuit 500 can be configured to connect the second current source 632 to the second pin 502 via switch control (e.g., controlling the second switch 642 to be closed and the switches 610 and 641 to be open), and use a comparator 650 to determine whether moisture is present in the second pin 502 based on a second voltage value (or a second resistance value of the second pin 502 corresponding to the second voltage value) obtained as the voltage value of the second pin 502 when the second current source 632 is connected to the second pin 502. The power control circuit 500 can use the comparator 650 to determine the presence of moisture, for example, when the second voltage value (or second resistance value) is within a specified second range, and to determine the absence of moisture when the first voltage value (or first resistance value) is not within the specified second range. According to an embodiment, the specified first range for determining the abnormal state and the specified second range for determining the presence of moisture can be different ranges.

[0147] According to an embodiment, comparator 650 can be used to monitor the voltage at the second pin 502 (or the second port 512). For example, comparator 650 can obtain an output value (e.g., a high value (e.g., 1) or a low value (e.g., 0)) by comparing the voltage at the second pin 502 with a reference voltage Vref. The reference voltage of comparator 650 can be set to be different or the same depending on the components connected to the second pin 502 (e.g., resistor 620, first current source 631, or second current source 632 to the second pin 502).

[0148] According to an embodiment, the power control circuit 500 can be configured to monitor the voltage of the second pin 502 via a comparator 650 to identify whether an external electronic device is connected. The power control circuit 500 can also be configured to monitor the voltage of the second pin 502 via the comparator 650 to identify the power profile that the external electronic device can provide. The power control circuit 500 can monitor the voltage of the second pin 502 via the comparator 650 to determine whether the resistance value corresponding to the second pin 502 is within a specified range. When the resistance value corresponding to the second pin 502 is within the specified range, the power control circuit 500 can identify or determine that moisture is present in the connector. When the resistance value corresponding to the second pin 502 is not within the specified range, the power control circuit 500 can identify or determine that moisture is not present in the connector.

[0154] According to an embodiment, the power control circuit 500 can monitor the voltage of the first pin 501 via the comparator 710 to determine whether power is being supplied from an external electronic device (e.g., via the first pin 501). Figure 4 External electronic device 410) supplies power to the battery (e.g., Figure 1The power (or voltage) for charging the battery 189. For example, when the voltage value (Vbus value) of the first pin 501 is detected to be lower than (or less than) the reference voltage value (Vref value) (e.g., output low value (e.g., 0)), the power control circuit 500 can determine that no voltage for charging the battery is being supplied from the external electronics through the first pin 501. When the voltage value (e.g., Vbus value) of the first pin 501 is detected to be greater than (or higher than) the reference voltage value (Vref value) (e.g., output high value (e.g., 1)), the power control circuit 500 can determine that the voltage for charging the battery is being supplied normally from the external electronics through the first pin 501.

For example, the power control circuit 500 may be included in the power management module of the electronic device (e.g., Figure 1 In the power management module 188).

[0169] Figure 9 This is a flowchart illustrating an example method of operating an electronic device according to an embodiment of the present disclosure.

[0170] In the following embodiments, each operation may be executed sequentially, but not necessarily sequentially. For example, the order of each operation can be changed, and at least two operations can be executed in parallel. In the following embodiments, some operations may be omitted, or additional operations may be performed.

[0171] According to an embodiment, operating electronic devices (e.g., Figure 1 Electronic device 101 or Figure 2 The method of the electronic device 200 can be performed by the processor of the electronic device (e.g., Figure 1 The processor 120) or the power control circuit of the electronic device (e.g., Figures 5 to 8 The power control circuit 500 is executed.

[0172] Reference Figure 9 In operation 910, the electronic device can identify the connector (e.g., Figure 1 Interface 177 or Figures 2 to 3b Moisture may be present in the connector 210. For example, moisture may be present in the electronic device in an external electronic device (e.g., Figure 4 The external electronic device (410) detects the presence of moisture in the connector when it is connected to the electronic device via the connector. For example, the electronic device can detect the presence of moisture in the connector before the external electronic device is connected to it.

[0173] According to an embodiment, the electronic device can determine the connection with the second pin (e.g., Figure 5 , Figure 6a , Figure 6b , Figure 7 and Figure 8 The second pin 502 (which can be called Figures 5 to 8 The system checks whether the resistance value (or voltage) corresponding to the second pin 502 is within a specified range, thereby identifying moisture in the connector. For example, by checking whether the resistance value (or voltage) of the second pin is within a specified range, the system checks whether moisture is present in the connector via the second port (e.g., ...). Figures 5 to 8 The second port 512 is connected to a current source (e.g., Figure 6b When the first current source 631 and / or the second current source 632 are present, the electronic device can use a comparator (e.g., Figure 6b The comparator 650 determines whether the resistance value corresponding to the second pin is within a specified range. If the resistance value is within the specified range, the electronic device can detect the presence of moisture in the connector. If the resistance value is outside the specified range, the electronic device can detect the absence of moisture in the connector.

[0174] In operation 920, based on the identification of moisture in the connector, the electronic device can be configured such that: the second port electrically connected to the second pin is disconnected from ground; and / or not connected to the first pin (e.g., Figures 5 to 8 The first pin 501 can supply power from an external electronic device, or reduce the voltage value of the power supplied through the first pin. For example, based on the detection of moisture in the connector when the external electronic device is connected to the electronic device, the electronic device can be configured such that: the second port electrically connected to the second pin is disconnected from ground; and / or power is not supplied from the external electronic device through the first pin, or the voltage value of the power supplied through the first pin is reduced. For example, based on the detection of moisture in the connector and the external electronic device being connected to the electronic device through the connector, the electronic device can be configured such that: the second port electrically connected to the second pin is disconnected from ground; and / or power is not supplied from the external electronic device through the first pin, or the voltage value of the power supplied through the first pin is reduced. In operation 920, since power is not supplied through the first pin or power with a low voltage value is supplied through the first pin, connector corrosion caused by moisture can be prevented / reduced.

[0175] According to an embodiment, the electronic device can be configured to switch (e.g., between the second port and ground) Figure 6a or Figure 6bThe open / closed state of switch 610 changes from a first state (e.g., closed state) to a second state (e.g., open state), thereby disconnecting the second port from ground. In this case, other switches connected to the second port (e.g., Figure 6b The first switch 641 and the second switch 642 can also be set to the off state.

[0176] According to an embodiment, the voltage value of the power supply can be set, for example, below (or less than) a reference voltage (e.g., Figure 7 The reference voltage Vref of comparator 710.

[0177] According to an embodiment, the electronic device can be configured to perform an operation (e.g., operation 910) to identify (or determine) the presence of moisture in the connector and / or to disconnect the second port from ground (e.g., operation 920) before performing or completing negotiation for determining the charging power between the external electronic device and the electronic device. For example, operations 910 and / or 920 can be performed before performing or completing negotiation for determining the charging power between the external electronic device and the electronic device.

[0178] According to an embodiment, the electronic device can be configured to: upon completion of negotiation for determining the charging power between the external electronic device and the electronic device, and upon charging the battery with at least a portion of the power supplied by the external electronic device, perform an operation to identify the presence of moisture in the connector (e.g., operation 910) and / or perform an operation to disconnect the second port from ground (e.g., operation 920). For example, operations 910 and / or 920 can be performed upon completion of negotiation for determining the charging power between the external electronic device and the electronic device, and upon charging the battery with at least a portion of the power supplied by the external electronic device.

[0179] According to an embodiment, the electronic device can be configured to: perform an operation to identify the presence of moisture in the connector (e.g., operation 910) before the external electronic device is connected to the electronic device, and perform an operation to disconnect the second port from ground (e.g., operation 920) after the external electronic device is connected to the electronic device (e.g., after performing or completing negotiation for determining the charging power between the external electronic device and the electronic device). For example, operation 910 can be performed before the external electronic device is connected to the electronic device, and operation 920 can be performed after the external electronic device is connected to the electronic device.

[0180] Figure 10 This is a flowchart illustrating an example method of operating an electronic device according to an embodiment of the present disclosure.

[0181] In the following embodiments, each operation may be executed sequentially, but not necessarily sequentially. For example, the order of each operation can be changed, and at least two operations can be executed in parallel. In the following embodiments, some operations may be omitted, or additional operations may be performed.

[0182] According to an embodiment, electronic devices (e.g., Figure 1 Electronic device 101 or Figure 2 The operation method of the electronic device 200 can be determined by the processor of the electronic device (e.g., Figure 1 The processor 120) or the power control circuit of the electronic device (e.g., Figures 5 to 8 The power control circuit 500 is executed.

[0183] Reference Figure 10 In operation 1010, the electronic device can identify (or determine) the connector (e.g., Figure 1 Interface 177 or Figures 2 to 3b Moisture may be present in the connector 210. For example, moisture may be present in the electronic device in an external electronic device (e.g., Figure 4 The external electronic device (410) detects the presence of moisture in the connector when it is connected to the electronic device via the connector. For example, the electronic device can detect the presence of moisture in the connector before the external electronic device is connected to it.

[0184] According to an embodiment, the electronic device can determine the connection with the second pin (e.g., Figures 5 to 8 The system checks whether the resistance value (or voltage) corresponding to the second pin (502) is within a specified range, thereby identifying the presence of moisture in the connector. For example, by checking whether the resistance value (or voltage) corresponding to the second pin (502) is within a specified range, the system can detect moisture in the connector. Figures 5 to 8 The second port 512 is connected to a current source (e.g., Figure 6b When the first current source 631 or the second current source 632 is available, the electronic device can use a comparator (e.g., Figure 6b The comparator 650 determines whether the resistance value corresponding to the second pin is within a specified range. Based on the resistance value being within the specified range, the electronic device can identify or determine the presence of moisture in the connector. Based on the resistance value not being within the specified range, the electronic device can identify or determine the absence of moisture in the connector.

[0185] In operation 1020, based on the identification of moisture in the connector, the electronic device can communicate with the third pin (e.g., Figure 8 The third port (e.g., the third pin 503) is electrically connected to the third port. Figure 8 The third port 513) outputs a request signal (hereinafter referred to as the power-related request signal or request signal) to request that the signal not be transmitted through the first pin (e.g., Figures 5 to 8The first pin 501 supplies (or disconnects) power from an external electronic device or reduces the voltage value of the power supplied through the first pin. For example, based on the identification or determination of moisture in the connector when the external electronic device is connected to the electronic device, the electronic device can output a power-related request signal through a third port electrically connected to the third pin. For example, the electronic device can output a power-related request signal through a third port electrically connected to the third pin based on the determination that the resistance value is within a specified range when the external electronic device is connected to the electronic device. For example, the electronic device can output a power-related request signal through the third port based on the identification (or determination) of moisture in the connector and the external electronic device being connected to the electronic device through the connector. For example, when moisture is identified in the connector and the external electronic device is connected to the electronic device through the connector, the electronic device can determine whether the voltage value supplied through the first pin is higher than or equal to a reference voltage, and can output a power-related request signal through the third port based on the determination that the voltage value supplied through the first pin is higher than or equal to the reference voltage. The request signal output through the third port can be transmitted to the external electronic device. When an external electronic device supports protection functions such as the Hiccup function, in response to a request signal, the external electronic device can use the corresponding protection function to prevent (or disconnect) power from the first pin, or can reduce the voltage value of the power supplied through the first pin. Depending on the operation of the external electronic device based on the request signal, it can prevent or reduce connector corrosion caused by moisture by either not supplying power through the first pin or supplying power with a low voltage value through the first pin.

[0186] In operation 1030, the electronic device can, based on the fact that the voltage value of the power supplied to the first pin remains substantially the same after a specified time following the output of the request signal through the third port, switch (e.g., between the second port and ground) is set between the second port and ground. Figure 6a or Figure 6b The open / closed state of the switch 610) changes from a first state (e.g., closed state) to a second state (e.g., open state), causing the second port to be disconnected from ground.

[0187] According to an embodiment, when the difference between the first voltage value and the second voltage value is within a specified range, the electronic device can determine that the voltage value of the power supplied to the first pin remains substantially the same, wherein the first voltage value is the voltage value supplied to the first pin before the request signal is output through the third port, and the second voltage value is the voltage value of the power supplied to the first pin after a specified time has elapsed after the request signal is output through the third port.

[0188] According to an embodiment, when the difference between the first voltage value and the second voltage value is not within a specified range, the electronic device can determine that the voltage value of the power supplied to the first pin is not kept substantially the same, wherein the first voltage value is the voltage value supplied to the first pin before the request signal is output through the third port, and the second voltage value is the voltage value of the power supplied to the first pin after a specified time has elapsed after the request signal is output through the third port.

[0189] According to an embodiment, when both the first voltage value and the second voltage value are higher than a reference voltage value (e.g., Figure 7 When the reference voltage Vref value of the comparator 710 is obtained, the electronic device can determine that the voltage value of the power supplied to the first pin remains substantially the same, wherein the first voltage value is the voltage value supplied to the first pin before the request signal is output through the third port, and the second voltage value is the voltage value of the power supplied to the first pin after a specified time has elapsed after the request signal is output through the third port.

[0190] According to an embodiment, when the first voltage value is higher than the reference voltage value (e.g., Figure 7 When the reference voltage Vref value of the comparator 710 is lower than (or less than) the reference voltage value, the electronic device can determine that the voltage value of the power supplied to the first pin is not kept substantially the same, wherein the first voltage value is the voltage value supplied to the first pin before the request signal is output through the third port, and the second voltage value is the voltage value of the power supplied to the first pin after a specified time has elapsed after the request signal is output through the third port.

[0191] Figure 11 This is a flowchart illustrating an example method of operating an electronic device according to an embodiment of the present disclosure.

[0192] In the following embodiments, each operation may be executed sequentially, but not necessarily sequentially. For example, the order of each operation can be changed, and at least two operations can be executed in parallel. In the following embodiments, some operations may be omitted, or additional operations may be performed.

[0193] According to an embodiment, electronic devices (e.g., Figure 1 Electronic device 101 or Figure 2 The operation method of the electronic device 200 can be determined by the processor of the electronic device (e.g., Figure 1 The processor 120) or the power control circuit of the electronic device (e.g., Figures 5 to 8 The power control circuit 500 is executed.

[0194] Reference Figure 11 In operation 1110, the electronic device can identify the connector (e.g., Figure 1 Interface 177 or Figure 2 , Figure 3a and Figure 3b (It can be called) Figures 2 to 3b Moisture may be present in the connector 210 of the electronic device. For example, moisture may be present in the external electronic device (e.g., Figure 4 When the external electronic device 410 is connected to the electronic device, moisture is detected in the connector. For a description of operation 1110, please refer to... Figure 9 Operation 910 or Figure 10 The description of operation 1010 is omitted here.

[0195] In operation 1120, based on the identification (or determination) of moisture in the connector, the electronic device can determine (or identify) whether an external electronic device supports a protection function. For example, the electronic device can determine whether the external electronic device supports a protection function based on the identification of moisture in the connector when the external electronic device is connected to it. The protection function can be, for example, a hiccup function, but is not limited to this. Various types of overcurrent protection or overvoltage protection functions can be used as protection functions.

[0196] According to an embodiment, via the second pin (e.g., Figures 5 to 8 During the process of establishing a communication connection between the second pin 502 and an external electronic device, the electronic device can determine whether the external electronic device supports protection functions based on the performance information received from the external electronic device.

[0197] In operation 1130, based on the determination that the external electronic device supports the protection function, the electronic device can communicate with the third pin (e.g., Figures 5 to 8 The third port (e.g., the third pin 503) is electrically connected to the third port. Figures 5 to 8 The third port 513) outputs a request signal to request that the signal not be sent through the first pin (e.g., Figures 5 to 8 The first pin 501 supplies (or disconnects) power or reduces the voltage value of the power supplied through the first pin. For a description of operation 1130, please refer to... Figure 10 The description of operation 1020 is provided. Therefore, the description need not be repeated here.

[0198] In operation 1131, the electronic device can, based on the fact that the voltage value of the power supplied to the first pin remains substantially the same after a specified time following the output of the request signal through the third port, switch (e.g., between the second port and ground) is set between the second port and ground. Figure 6a or Figure 6bThe open / closed state of switch 610 is changed from a first state (e.g., closed state) to a second state (e.g., open state), causing the second port to be disconnected from ground. For a description of operation 1131, please refer to... Figure 10 The description of operation 1030 is omitted here.

[0199] In operation 1140, based on the determination (or identification) that the external electronic device does not support the protection function, the electronic device may request, without outputting a request signal through the third port electrically connected to the third pin, to request that power not be supplied (or disconnected) through the first pin or to reduce the voltage value of the power supplied through the first pin. For example, when the external electronic device does not support the protection function, the electronic device may not output a request signal through the third port electrically connected to the third pin. If the external electronic device does not support the protection function, even if a request signal is transmitted to the external electronic device, the external electronic device may not respond to the request signal and perform the protection function; therefore, transmitting the request signal corresponds to unnecessary operation. The electronic device can selectively transmit the request signal only when necessary, based on the determination in operation 1120 regarding whether the external electronic device supports the protection function, thereby improving the efficiency of power and resource utilization.

[0200] In operation 1141, the electronic device can change the open / closed state of a switch located between the second port and ground from a first state (e.g., closed state) to a second state (e.g., open state), thereby disconnecting the second port from ground.

[0201] Figure 12 This is a flowchart illustrating an example method of operating an electronic device according to an embodiment of the present disclosure.

[0202] In the following embodiments, each operation may be executed sequentially, but not necessarily sequentially. For example, the order of each operation can be changed, and at least two operations can be executed in parallel. In the following embodiments, some operations may be omitted, or additional operations may be performed.

[0203] According to an embodiment, electronic devices (e.g., Figure 1 Electronic device 101 or Figure 2 The operation method of the electronic device 200 can be determined by the processor of the electronic device (e.g., Figure 1 The processor 120) or the power control circuit of the electronic device (e.g., Figures 5 to 8 The power control circuit 500 is executed.

[0204] According to an embodiment, Figure 12 Operations 1210 and / or 1220 can, for example, in Figure 9 After the operation of 920, Figure 10 After 10:30 or Figure 11 Execute after operation 1131 or 1140.

[0205] Reference Figure 12 In operation 1210, the electronic device can detect that there is essentially no moisture in the connector. For example, the electronic device can detect that there is essentially no moisture in the connector when the external electronic device is connected to the connector. For example, the electronic device can detect that there is essentially no moisture in the connector when the external electronic device is not connected to the connector.

[0206] According to an embodiment, the electronic device can determine the connection with the second pin (e.g., Figures 5 to 8 The resistance value corresponding to the second pin 502 is checked to determine if it is within a specified range, thereby identifying that there is essentially no moisture in the connector (e.g., identifying that moisture has been removed). For example, the second pin is checked through the second port (e.g., Figure 5 or Figure 8 The second port 512 is connected to a current source (e.g., Figure 6b When the first current source 631 and / or the second current source 632 are present, the electronic device can use a comparator (e.g., Figure 6b The comparator 650 determines whether the resistance value corresponding to the second pin is within a specified range. If the resistance value is within the specified range, the electronic device can detect the presence of moisture in the connector. If the resistance value is outside the specified range, the electronic device can detect the absence of moisture in the connector.

[0207] In operation 1220, based on the identification that there is essentially no moisture in the connector, the electronic device can be configured such that the second port is connected to ground, and power is supplied via the first pin through an external electronic device. For example, based on the identification that there is essentially no moisture in the connector while the external electronic device is connected to the connector, the electronic device can be configured such that the second port is connected to ground, and power is supplied via the first pin through the external electronic device. For example, based on the identification that there is essentially no moisture in the connector and the external electronic device is connected to the connector, the electronic device can be configured such that the second port is connected to ground, and power is supplied via the first pin through the external electronic device.

[0208] According to an embodiment, the electronic device can be configured to switch (e.g., between the second port and ground) Figure 6a or Figure 6b The open / closed state of switch 610 changes from a second state (e.g., open state) to a first state (e.g., closed state), thereby connecting the second port to ground. Based on the identification that the second port is connected via a pull-down resistor (e.g., ... Figure 6a and Figure 6bThe resistor 620 is connected to ground, allowing external electronic devices to identify the electronic device as a powered device, and a battery (e.g., a power source) can be supplied to the electronic device via the first pin. Figure 1 The battery (189) is charged with electricity.

[0209] Through the above Figure 12 By operating steps 1210 and 1220, the electronic device can return to its normal state where there is no moisture, and an external electronic device can supply power to the electronic device.

[0210] Figure 13 This is a flowchart illustrating an example method of operating an electronic device according to an embodiment of the present disclosure.

[0211] In the following embodiments, each operation may be executed sequentially, but not necessarily sequentially. For example, the order of each operation can be changed, and at least two operations can be executed in parallel. In the following embodiments, some operations may be omitted, or additional operations may be performed.

[0212] According to an embodiment, electronic devices (e.g., Figure 1 Electronic device 101 or Figure 2 The operation method of the electronic device 200 can be determined by the processor of the electronic device (e.g., Figure 1 The processor 120) or the power control circuit of the electronic device (e.g., Figures 5 to 8 The power control circuit 500 is executed.

[0213] According to an embodiment, Figure 13 Operations 1310 and / or 1320 can, for example, in Figure 9 After the operation of 920, Figure 10 After 10:30 or Figure 11 Execute after operation 1131 or 1140.

[0214] Reference Figure 13 In operation 1310, the electronic device can be based on a second port (e.g., Figures 5 to 8 The second pin (e.g., the second port 512) is obtained when it is disconnected from ground. Figures 5 to 8 The voltage value of the second pin (502) is used to identify whether an external electronic device is connected to the electronic device via a connector. According to an embodiment, the electronic device can determine whether the voltage of the second pin is higher than (e.g., greater than) a reference voltage; when the voltage of the second pin is higher than (e.g., greater than) the reference voltage, it can identify that an external electronic device is connected to the electronic device via a connector; and when the voltage of the second pin is lower than (e.g., less than) the reference voltage, it can identify that an external electronic device is not connected to the electronic device via a connector. In operation 1310, the electronic device can determine whether the voltage of the second pin (e.g., 502) is higher than (e.g., greater than) a reference voltage. Figure 3b The voltage of the second pin is measured with the CC pin disconnected from ground, thus determining whether external electronics are still connected to the connector even if moisture is present in the connector.

[0215] In operation 1320, based on the identification that an external electronic device is connected to the electronic device via a connector, the electronic device can provide a guidance message for disconnecting the external electronic device via a display.

[0216] According to an embodiment, the electronic device can be displayed via a display (e.g., Figure 1 The display module 160 displays a boot message for disconnecting the external electronic device. According to an embodiment, the electronic device can output the boot message for disconnecting the external electronic device via a speaker.

[0217] According to an embodiment, the guidance message may include a message such as "Please remove the charger from the electronic device."

[0218] According to an embodiment, the electronic device may display information (e.g., an icon) indicating that moisture has been detected in the connector, either together with or separately from the guidance message, on the display.

[0219] By following the guidance message provided by the operator 1320, the user can identify the presence of moisture and remove external electronic devices (e.g., charging devices) from the electronic device. This prevents / reduces moisture corrosion of the electronic device.

[0220] Figure 14 This is a flowchart illustrating an example method of operating an electronic device according to an embodiment of the present disclosure.

[0221] In the following embodiments, each operation may be executed sequentially, but not necessarily sequentially. For example, the order of each operation can be changed, and at least two operations can be executed in parallel. In the following embodiments, some operations may be omitted, or additional operations may be performed.

[0222] According to an embodiment, electronic devices (e.g., Figure 1 Electronic device 101 or Figure 2 The operation method of the electronic device 200 can be determined by the processor of the electronic device (e.g., Figure 1 The processor 120) or the power control circuit of the electronic device (e.g., Figures 5 to 8 The power control circuit 500 is executed.

[0223] Reference Figure 14 In operation 1410, the electronic device can operate under normal conditions.

[0224] According to an embodiment, under normal conditions, the electronic device can control access via a second port (e.g., Figures 5 to 8 The second port 512) and the CC pin (e.g., Figures 5 to 8 The second pin 502 is electrically connected to the second control circuit (e.g., Figures 5 to 8 The second control circuit 522 includes a switch (e.g., Figure 6b (Switches 610, 641, and / or 642), to pull down resistor Rd (e.g., ...) at corresponding time intervals. Figure 6a and Figure 6b Resistor 620), first current source (e.g., Figure 6b First current source 631) and second current source (e.g., Figure 6b Either of the second current source (632) can be selectively connected to the CC pin. Therefore, under normal conditions, only one of the pull-down resistor, the first current source, and the second current source can be connected to the CC pin in each time interval.

[0225] For example, during the first time interval in normal operation (e.g., the first time interval in Table 1, the third time interval, or the seventh time interval in Table 3), the electronic device can control switch 610 to be closed and control the first switch 641 and the second switch 642 to be open, thereby connecting the second pin to ground via the pull-down resistor Rd.

[0226] For example, in a second time interval (e.g., the second time interval in Table 1 or the fourth time interval in Table 2) following the first time interval under normal conditions, the electronic device can control the first switch 641 to be closed and control the switches 610 and 642 to be open, thereby electrically connecting the first current source 631 to the CC pin. The electronic device can use the first current source 631 to determine whether the CC pin is in an abnormal state.

[0227] For example, in a third time interval (e.g., the fifth time interval in Table 2 or the ninth time interval in Table 3) following the second time interval under normal conditions, the electronic device can control the second switch 642 to be closed and can control switches 610 and 641 to be open, thereby electrically connecting the second current source 632 to the CC pin. According to an embodiment, the second switch 642 can be controlled to be closed based on determining that the CC pin is in an abnormal state. The electronic device can use the second current source 632 to determine whether moisture is present in the CC pin under abnormal conditions.

[0228] According to an embodiment, the electronic device can sequentially and repeatedly perform the operations of the first time interval, the second time interval, and the third time interval described above.

[0229] According to an embodiment, when an external electronic device (e.g., Figure 4 The external electronic device 410) is not connected via a connector (e.g., Figure 1 Interface 177 or Figures 2 to 3b When the connector 210 is connected to the electronic device, the electronic device can operate under normal conditions.

[0230] According to an embodiment, in an external electronic device (e.g., Figure 4 External electronic device 410) via connector (e.g., Figure 1 Interface 177 or Figure 2 When the connector 210 is connected to the electronic device, the electronic device can operate under normal conditions until moisture is detected in the connector.

[0231] In operation 1420, the electronic device can identify or determine the presence of moisture in the connector. According to an embodiment, the electronic device can identify the presence of moisture in at least one pin of the connector. For a description of operation 1420, please refer to... Figure 10 Operation 1010 or Figure 11 The description of operation 1110 is omitted here.

[0232] In operation 1430, based on the detection of moisture in the connector, the electronics can be configured to connect the CC pin to ground. For example, the electronics can be configured to control switch 610 to be closed, causing the CC pin to be connected to ground via pull-down resistor 620. Because moisture is detected, the CC pin is connected to ground, allowing the electronics to bring the voltage of the CC pin to a low state (e.g., close to 0V), and to detect that an external electronics device is connected to the electronics device via a connector.

[0233] In operation 1440, the electronic device can recognize that an external electronic device is connected to it via a connector. According to an embodiment, the electronic device can recognize the voltage of the CC pin when the CC pin is connected to ground via a pull-down resistor, thereby recognizing that an external electronic device is connected to it via a connector.

[0234] In operation 1450, the electronic device can determine via the Vbus pin (e.g., Figures 5 to 8 The voltage (first Vbus voltage) supplied to the electronic device from an external electronic device (pin 501) is checked to see if it is higher than (e.g., greater than) a reference voltage Vref. According to an embodiment, the electronic device can use the first port (e.g., via the Vbus pin) to check if the voltage supplied to the electronic device from an external electronic device (pin 501) is higher than (e.g., greater than) a reference voltage Vref. Figures 5 to 8 The first control circuit (e.g., the first port 511) is connected to the first control circuit. Figures 5 to 8 The comparator (e.g., in the first control circuit 521) included in the first control circuit 521) Figure 7 The electronic device uses the output value of comparator 710 to determine whether the first Vbus voltage is higher than the Vref voltage. For example, when the comparator output value is a first value (e.g., 1), the electronic device can determine that the first Vbus voltage is higher than the Vref voltage. When the first Vbus voltage is higher than the Vref voltage, operation 1460 can be performed. For example, when the comparator output value is a second value (e.g., 0), the electronic device can determine that the first Vbus voltage is lower than the Vref voltage. When the first Vbus voltage is lower than the Vref voltage, operation 1430 can be performed again.

[0235] In operation 1460, based on Vbus>Vref in operation 1450, the electronic device can access the device via the DP / DN pin (e.g., Figures 5 to 8 The third pin (503) sends a request signal to an external electronic device to request that the Vbus voltage be supplied from the external electronic device without passing through the Vbus pin, or to reduce the Vbus voltage. According to an embodiment, the request signal can be generated based on a process that electrically connects the DP / DN pin to ground (GND processing). For example, the request signal may correspond to the voltage value of the DP / DN pin generated by the process of electrically connecting the DP / DN pin to ground (GND).

[0236] In operation 1470, the electronic device may wait for a specified time (e.g., five seconds). According to an embodiment, the electronic device may wait for the specified time after sending a request signal. According to an embodiment, the specified time the electronic device waits may be longer than the minimum time required for an external electronic device to perform a protection function (e.g., a hiccup function) in response to the request signal.

[0237] In operation 1480, the electronic device can determine whether the voltage (second Vbus voltage) supplied to the electronic device from an external electronic device via the Vbus pin after a specified time is higher than (e.g., greater than) a reference voltage (Vref voltage). According to an embodiment, the electronic device can use the output value of a comparator included in a first control circuit connected to the first pin via a first port to determine whether the second Vbus voltage is higher than the Vref voltage. For example, if the comparator output value is a first value (e.g., 1), the electronic device can determine that the second Vbus voltage is higher than the Vref voltage. When the second Vbus voltage is higher than the Vref voltage, operation 1490 can be performed. For example, when the comparator output value is a second value (e.g., 0), the electronic device can determine that the second Vbus voltage is lower than the Vref voltage. When the second Vbus voltage is lower than (or less than) or equal to the Vref voltage, operation 1491 can be performed.

[0238] In operation 1490, when Vbus > Vref in operation 1480, the electronic device can be configured to disconnect the CC pin from ground. For a description of operation 1490, please refer to... Figure 10 The description of operation 1030 is provided. Therefore, the description need not be repeated here.

[0239] In operation 1491, the electronic device can maintain an electrical connection between the CC pin and ground.

[0241] In the following embodiments, each operation may be executed sequentially, but not necessarily sequentially. For example, the order of each operation can be changed, and at least two operations can be executed in parallel.

[0244] Reference Figure 15 In operation 1510, the electronic device can acquire the CC pin (e.g., Figures 5 to 8 The voltage of the second pin (502). According to an embodiment, the electronic device can measure the voltage of the CC pin with the CC pin disconnected from ground (GND). The electronic device can measure the voltage of the CC pin with the CC pin disconnected from ground, thereby determining whether an external electronic device is still connected to the electronic device through the connector even if moisture is present in the connector.

When the voltage of the CC pin is higher than the reference voltage, operation 1530 can be performed. When the voltage of the CC pin is lower than (e.g., less than) the reference voltage, operation 1510 can be performed.
