According to an embodiment, the processor may monitor data communicated through the at least one first pin for a predetermined time interval, and stop an operation of supplying the power when the data is not communicated within the predetermined time interval. According to an embodiment, the predetermined time interval may be a time interval after the ID of the external device is acquired. According to an embodiment, the predetermined time interval may be a predetermined time interval from a time point at which the power starts to be supplied.

According to an embodiment, the ID may have a resistance value.

According to an embodiment, the identification circuit may detect a change in an ID of the external device while communicating data with the external device.

According to an embodiment, the processor or the identification circuit may stop communication of the data in response to the change in the ID.

According to an embodiment, the processor or the identification circuit may allow the booster to stop an operation of supplying power in response to the change of the ID.

According to an embodiment, the electronic device may further include at least one charger electrically connected to the input/output interface, and a battery electrically connected to the charger.

According to an embodiment, the input/output interface may further include a fifth pin electrically connected to a charger, and acquire power from the external device through the fifth pin.

According to an embodiment, the input/output interface may support a travel adapter (TA).
