Claim 17:
18. A method for controlling an interface between an integrated circuit of an electronic device and an external device, the method comprising:
controlling, by an interface control switch, a mode of the interface between each of:
a first mode for data communication that connects the external device to the integrated circuit of the electronic device via one or more communication lines of the electronic device; and
a second mode for power transmission that connects a power source of the external device to a battery of the electronic device;

receiving, by the interface control switch, a reset signal from a reset line connecting the interface control switch to an overvoltage protection switch connected between the one or more communication lines of the electronic device and the reset line of the controller; and
activating, by the interface control switch, a high impedance mode at the integrated circuit of the electronic device in response to the reset signal, wherein the high impedance mode avoids power from the external line reaching the integrated circuit via the one or more communication lines of the electronic device.
