Method for detecting leakage current and electronic device supporting the same

A method comprising:

• detecting, by an interface control unit, a coupling of an external device to an electronic device;
• identifying, by the interface control unit, a type of the coupled external device;
• when the external device is identified as a current detecting device, generating, by the interface control unit, a first control signal for turning off power to one or more sub-systems of the electronic device, and a second control signal for setting a first path to supply the one or more sub-systems with power from the current detecting device;
• and
• transmitting, by the interface control unit, the first control signal to the one or more sub-systems and the second control signal to one or more switches.

A non-transitory computer-readable recording medium that records one or more commands,

• wherein when the commands are executed by at least one processor, the at least one processor performs the operations of:
• detecting, by an interface control unit, a coupling of an external device to an electronic device;
• identifying, by the interface control unit, a type of the coupled external device;
• when the external device is identified as a current detecting device, generating, by the interface control unit, a first control signal for turning off power to one or more sub-systems of an electronic device, and a second control signal for setting a first path to supply the one or more sub-systems with power from the current detecting device;
• and
• transmitting, by the interface control unit, the first control signal to the one or more sub-systems and the second control signal to one or more switches, to allow the current detecting device to measure a leakage current of the electronic device.
