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

In operation 611, the electronic device (e.g., the processor, the USB controller 111, and/or the identification circuit 130) may detect the restored ID. For example, the electronic device may detect that the resistance at the identification pin of the input/output interface 140 has been changed from a second resistance value to a first resistance value through the identification circuit 130. The electronic device may perform reconnection with the external device 200 in response to the detection of the restored ID. For example, the electronic device may perform a connection operation with the external device shown in FIG. 4. In this case, according to various embodiments, operation 405 may not be performed because the VBUS function of the booster 142 is turned on. The electronic device may increase the amount of VBUS power.

Depending on cases, the electronic device may turn off the VBUS function of the booster 142 in the power saving mode. In this case, when the electronic device reconnects to the external device 200, the electronic device may perform operation 405.

FIG. 7 is a schematic flowchart of a power saving method of an electronic device according to an embodiment.
