Abstract
The present disclosure provides a circuit protection system and a circuit protection method for an electronic system. The circuit protection system includes a main chip, a power chip powering the main chip, a basic input/output system (BIOS) and a control unit. The control unit detects the potential of a PW_OK signal output from the power chip to the main chip, and gets the current state of the electronic system through the BIOS, thereby determining whether the current state of the main chip corresponds to a predetermined state for the main chip which defined in the current state of the electronic system. If not, the control unit outputs a signal to disable the main chip. The present disclosure disables the main chip instantly when the voltage provided thereto is excessive or insufficient, thereby avoiding the damage caused by excessive or insufficient voltage.
