Method for controlling at least one pin included in interface so as to switch to open state in response to moisture detection and electronic device for performing same

An electronic device comprising:

• a housing;
• an interface configured to be connected to the housing or to be exposed through the housing, and to comprise at least one configuration channel (CC) pin;
• a circuit configured to be disposed in the housing, to comprise a current generator and a comparator, and to be electrically connected to the interface;
• at least one switch disposed between the current generator and the at least one CC pin;
• a processor configured to be disposed in the housing and to be operatively connected to the interface and the circuit;
• and
• a memory configured to be operatively connected to the processor,
• wherein the memory stores instructions that, when executed, cause the processor to:
• detect moisture corresponding to the at least one CC pin based on the comparator in a state in which the at least one CC pin is connected to the current generator,
• control the at least one switch not to connect the at least one CC pin with the current generator upon detecting the moisture,
• identify whether the moisture has evaporated based on a secondary bus (SBU) pin included in the interface, and
• control, in response to the moisture having evaporated, the at least one switch to connect the at least one CC pin with the current generator.
