An overcurrent protection method is provided. The overcurrent protection method is applied to a USB with a PD function. The overcurrent protection method includes the steps of converting an input voltage into a first voltage to provide power to the first electronic device; determining whether the working current of the first electronic device is greater than a first default value; determining whether the working current of the first electronic device is greater than a second default value; in response to the working current being greater than the first default value, a first sensing signal is generated to disable a switch and to form an open circuit between the first electronic device and the second electronic device; and in response to the working current being greater than the second default value, conversion of the input voltage into the first voltage is stopped.

Overcurrent protection circuit and method thereof for USB with a power delivery function

A display apparatus is provided. The display apparatus includes a display panel and a display controller. The display controller is electrically connected to a USB Type-C interface of a host via a USB Type-C interface of the display apparatus. In response to the USB Type-C interface of the display apparatus being in a USB Type-C default pin-assignment mode, the display controller receives an image signal from the host via two USB SuperSpeed channels of the USB Type-C interface of display apparatus. In response to a display mode of the display apparatus satisfying a specific condition, the display controller controls the USB Type-C interface of the display apparatus to enter a USB Type-C first pin assignment mode, so that the host utilizes the four USB SuperSpeed channels of the USB Type-C interface of the display apparatus to transmit the image signal to the display controller.
