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.

Abstract: In an electronic device and a method for operating the electronic device according to various embodiments, the electronic device may comprise a housing, a USB Type-C connector configured to be connected to the housing or exposed through the housing and to include at least one configuration channel (CC) pin, a circuit configured to be disposed in the housing and connected electrically to the connector, and a processor configured to be disposed in the housing and connected electrically to the circuit. The circuit may be configured to transmit and receive a packet through the CC pin. The packet may sequentially comprise a message header, a first vendor defined message (VDM) header, and a second VDM header including a product identifier and a data type. Further, various other embodiments can be implemented according to the present disclosure.
