Abstract: An electronic device including a PDIC, a charging IC, and a processor. The PDIC determines whether an external device is connected to the USB port, through a first pin of a USB port. The charging IC outputs a first voltage, which is a voltage obtained by boosting a voltage provided by a battery, to the external device through a second pin, when the external device is connected to the USB port. The processor is configured to determine whether the external device connected to the USB port is a first external device having a specified VID and a specified PID, through a third pin of the USB port, and to transmit a first signal, which controls the charging IC to output a second voltage having a magnitude less than the first voltage, to the charging IC when the first external device is connected to the USB port.
