摘要

An electronic device is disclosed. The electronic device comprises: a housing, an input/output interface, which includes a plurality of pogo pins exposed through a portion of the housing, and can be connected to an external device by a wire, an identification circuit, which is electrically connected to the input/output interface to identify the external device, a processor electrically connected to the identification circuit, and a booster electrically connected to the input/output interface to supply power to the external device. In addition, various embodiments understood from the specification are possible.

說明書

According to an embodiment, the first input/output interface 140 may be electrically connected to the first charger 190. The power pin of the first input/output interface 140 may be connected to the first charger 190. The power pin may be, for example, a VBUS out pin. The VBUS out pin may also be referred to as a power supply pin. The electronic device 100 may acquire a charging current from an external device connected to the first input/output interface 140 through the power pin. The first charger 190 may be a wireless power consortium (WPC) charger. The WPC charger may be used to charge the electronic device when TA is connected to a device supporting a pogo pin. The first input/output interface 140 may include a TA pin for TA connection separately in addition to the VBUS in and VBUS out pins.

Although FIG. 2 illustrates the first charger 190 and the second charger 180, the electronic device 100 may include one charger connected to the first input/output interface 140 or the second input/output interface 160.

Although not shown in FIG. 2, the electronic device 100 may further include at least one battery. The battery may be connected to at least one of the first charger 190 or the second charger 180. The battery may supply power to an external electronic device. For example, the battery may be electrically connected to the booster 142.
