Abstract
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.
