1. An electronic device comprising:
a power management integrated circuit configured to control a supply of a first power signal and a supply of a second power signal;
a connector comprising a first sub-pin array and a second sub-pin array;
a device recognition circuit configured to detect whether an external device is connected to the connector; and
a processor, wherein the first sub-pin array comprises a first power pin, a first data pin, and a first recognition pin,
wherein the second sub-pin array comprises a second power pin, a second data pin, and a second recognition pin;
wherein the first recognition pin and the second recognition pin are connected to the device recognition circuit;
wherein the processor is configured to:
based on a first resistance value detected in the first recognition pin, control the power management integrated circuit to supply the first power signal to the first power pin and to supply the second power signal to the second recognition pin,
perform Universal Serial Bus (USB) enumeration by using the first data pin to receive first identification information of the external device via the first recognition pin or the first data pin, and
identify whether the first identification information matches second identification information stored in a memory of the electronic device,
when the first identification information matches the second identification information, control the power management integrated circuit to cut off the supply of the first power signal and to maintain the supply of the second power signal,
wherein the first power signal is a signal obtained by boosting a power signal output via a terminal of the battery, and the second power signal is a power signal directly output via the terminal of the battery, and
wherein the first identification information comprises manufacturer information or product information of the external device.
