Abstract
A half bridge circuit driver chip and the protection method thereof are provided. The high side voltage detecting circuit connects to a high side signal output terminal and detects the high side turn-on voltage of the high side transistor, so as to obtain a high side turn-on signal. The low side voltage detection circuit connects to a low side signal output terminal and detects a low side turn-on voltage of a low side transistor, so as to obtain a low side turn on signal. When the high side turn-on signal and the low side turn-on signal are received by a protection circuit, a reset signal is generated. The reset signal is sent to the high side driving circuit for turning off the high side transistor and to the low side driving circuit for turning off the low side transistor.
