Abstract
A driving circuit for a power transistor. The driving circuit has a control pin to receive a control signal, a driving pin to provide a driving signal to control the power transistor, the driving signal is generated based on the control signal. The driving circuit also has a negative voltage isolation circuit connected between an isolation pin and an output pin, when the voltage at the output pin is greater than an isolation voltage, the voltage at the isolation pin is equal to the voltage at the output pin, and when the voltage at the output pin is less than the isolation voltage, the voltage at the isolation pin is clamped at a preset voltage value, the preset voltage value is in a range from −2V to −0.2V.
