SWITCHING CIRCUIT, POWER RECEIVING DEVICE USING THE SAME AND MODE SWITCHING METHOD THEREOF

Abstract: a switching circuit is disposed on a power receiving device and is electrically connected to a universal serial bus type-c (usb type-c) connector of the power receiving device. the switching circuit includes a determination module, a pd controller, and a mode switching module. the determination module is configured to: determine whether a power supply device supports a power delivery (pd) mode according to a pin signal of a configuration channel (cc) pin of the usb type-c connector; and generate a first switching signal based on the fact that the power supply device does not support the pd mode. the pd controller is electrically connected to the pin signal determination module. the mode switching module is selectively electrically connected to the pd controller and configured to be disconnected from the pd controller based on the first switching signal.
