Abstract: Disclosed is an electronic device comprising: a first input/output terminal; a second input/output terminal; a power source module; a first switch selectively connecting the first input/output terminal to the power source module; a second switch selectively connecting the second input/output terminal to the power source module; a diode having an anode electrically connected to the first input/output terminal and a cathode electrically connected to the power source module, so that the diode is connected in parallel to the first switch; and a control circuit for controlling the first switch and the second switch. The electronic device can prevent damage due to power from external electronic devices by controlling the first switch and the second switch in response to connection of the external electronic devices. Additional various embodiments identified through the specification are possible.

Abstract: Disclosed is an electronic device. According to an embodiment disclosed in this specification, an electronic device may include a first interface, a second interface, an input device generating a specified signal associated with disconnection of a first external electronic device, and a processor operatively connected to the first interface, the second interface, and the input device. The processor may be configured to receive power from the first external electronic device through the first interface in a state where the first external electronic device is connected to the first interface and a second external electronic device is connected to the second interface, and to receive power from the second external electronic device through the second interface when receiving the specified signal generated by the input device. Other various embodiments as understood from the specification are also possible.
