Abstract
A electronic device includes a USB Type-C interface, a switching circuit, a first signal path, and a second signal path. The USB Type-C interface is configured to connect to a USB Type-C device. The switching circuit is connected to the USB Type-C interface, the first signal path, and the second signal path. When the USB Type-C interface is connected to the USB Type-C device, the first signal path is connected to the USB Type-C interface through the switching circuit, and a level of a first pin of the USB Type-C interface is a first level. When the USB Type-C interface is disconnected from the USB Type-C device, the second signal path is connected to the USB Type-C interface through the switching circuit, and a level of the first pin is a second level. The first level is greater than the second level.
