Abstract
A gate driver is configured to drive a normally-on device and a normally-off device coupled in series. The gate driver controls the normally-on device in response to a PWM signal, and to control a normally-off device to maintain ON in normal operations. If an under voltage condition of a negative power supply of a first driver used to drive the normally-on device, or a positive power supply of a second driver used to drive the normally-off device, or an input supply voltage is detected, the normally-off device is controlled to be OFF.
