Abstract: According to an example embodiment, an electronic device includes: a universal serial bus (USB) power delivery integrated circuit (PDIC) configured to determine whether a first pin of a USB port of the electronic device is connected to a power delivery (PD) source; a charging circuitry configured to charge a battery of the electronic device with power supplied from the PD source through a second pin of the USB port; a memory configured to store computer-executable instructions; and a processor configured to execute the instructions by accessing the memory. When the USB PDIC determines that the first pin and the PD source are connected, the instructions may cause the processor to control a voltage of the second pin to be less than a threshold voltage while maintaining communication between the USB PDIC and the PD source through the first pin based on a state of the electronic device. In addition, various example embodiments may be possible.
