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, when the identification circuit 130 detects a specific device, the electronic device 100 may activate the booster 142. For example, when the specific device is detected through the identification circuit 130, the processor 110 or the identification circuit 130 may turn on at least some functions of the booster 142. The ADC or pogo ID may correspond to a resistance value of an external device. The resistance value of the external device may have a value of zero or more.

According to an embodiment, as shown in FIG. 1, the identification circuit 130 may be separate from the processor 110, but may be included in the processor 110. According to an embodiment, the identification circuit 130 may include a micro USB interface controller.

According to an embodiment, the identification circuit 130 may control other components disclosed herein. In the description with reference to FIG. 1, the identification circuit 130 has been described as a separate component from the processor 110, but the identification circuit 130 may be implemented by the processor 110. In the following descriptions, the identification circuit 130 may be a program (e.g., identification circuit driver) running on the processor 110.
