Abstract

An electronic device according to various embodiments may include a first connector including at least one first pin and at least one second pin configured to be connected to an external electronic device; a second connector comprising at least one third pin and at least one fourth pin configured to be connected to a power supply; a switching circuit; and a processor electrically connected to the first connector, the second connector, and the switching circuit, wherein the processor is configured to determine a connection with the external electronic device or a connection with the power supply, and the processor is set to cause, when connected to the external electronic device via the first connector and connected to the power supply via the second connector, power received from the power supply via the at least one third pin to be supplied to the at least one first pin using the switching circuit.

First claim

What is claimed is:

1. An electronic device comprising:
a first connector including at least one first pin and at least one second pin configured to be connected to an external electronic device;
a second connector comprising at least one third pin and at least one fourth pin configured to be connected to a power supply;
a switching circuit; and
a processor electrically connected to the first connector, the second connector, and the switching circuit,
wherein the processor is configured to determine a connection with the external electronic device or a connection with the power supply,
the processor is set to cause, when connected to the external electronic device via the first connector and connected to the power supply via the second connector, power received from the power supply via the at least one third pin to be supplied to the at least one first pin using the switching circuit, and
the processor is set to determine that power of the external electronic device is in an OFF state when a designated signal is not received using the first connector, and transmit information related to control of the power of the external electronic device via the at least one second pin of the first connector.

2. The electronic device of claim 1 , wherein the first connector supports a USB scheme.

3. The electronic device of claim 2 , wherein the at least one second pin includes a configuration channel (CC) pin.

4. The electronic device of claim 1 , wherein the information related to the control of the power is included in a vendor defined message (VDM) according to a power delivery (PD) communication standard.

5. The electronic device of claim 1 , wherein the second connector supports a universal serial bus (USB) scheme.

6. The electronic device of claim 1 , wherein the electronic device includes a head-mounted display (HMD) device capable of being engaged with the external electronic device.

7. An electronic device comprising:
a first connector including at least one first pin and at least one second pin configured to be connected to an external electronic device;
a second connector comprising at least one third pin and at least one fourth pin configured to be connected to a power supply;
a switching circuit set to supply, when connected to the external electronic device via the first connector and connected to the power supply via the second connector, power received from the power supply via the at least one third pin to the at least one first pin; and
a processor set to determine that power of the external electronic device is in an OFF state when a designated signal is not received using the first connector, and transmit information related to control of the power of the external electronic device via the at least one second pin of the first connector.

8. The electronic device of claim 7 , wherein the second connector supports a universal serial bus (USB) scheme.

9. The electronic device of claim 7 , wherein the first connector supports a USB scheme.

10. The electronic device of claim 9 , wherein the at least one second pin includes a configuration channel (CC) pin.

11. The electronic device of claim 7 , wherein the information related to the control of the power is included in a vendor defined message (VDM) according to a power delivery (PD) communication standard.

12. The electronic device of claim 7 , wherein the electronic device includes a head-mounted display (HMD) device capable of being engaged with the external electronic device.

13. A method of controlling power between electronic devices, comprising:
determining a connection with an external electronic device via a first connector comprising at least one first pin and at least one second pin;
determining a connection with a power supply via a second connector comprising at least one third pin and at least one fourth pin;
receiving power from the power supply via the at least one third pin;
supplying the power, which is received from the power supply via the at least one third pin, to the at least one first pin using a switching circuit when it is determined that an electronic device is connected to the external electronic device via the first connector and is connected to the power supply via the second connector; and
determining that power of the external electronic device is in an OFF state when a designated signal is not received using the first connector, and transmitting information related to control of the power of the external electronic device via the at least one second pin of the first connector.

14. The method of claim 13 , wherein the first connector supports a USB scheme.

15. The method of claim 14 , wherein the at least one second pin includes a configuration channel (CC) pin.

16. The method of claim 13 , wherein the information related to the control of the power is included in a vendor defined message (VDM) according to a power delivery (PD) communication standard.

17. The method of claim 13 , wherein the second connector supports a universal serial bus (USB) scheme.

18. The method of claim 13 , wherein the electronic device includes a head-mounted display (HMD) device capable of being engaged with the external electronic device.
