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.
