ELECTRONIC DEVICE AND METHOD FOR MANAGING POWER

摘要

An electronic device having a universal serial bus (USB) type-C interface and a power management method thereof are provided. In the method, when the electronic device is connected with another electronic device through a USB cable, the electronic device recognizes a USB port through a configuration channel. Also, the electronic device recognizes a connection direction of the USB cable and receives power information from the other electronic device through the configuration channel. Then, based on the received power information, the electronic device determines whether to enter a downstream facing port (DFP) mode or an upstream facing port (UFP) mode.
