Abstract
A gate driver and a control method thereof are provided. The gate driver is coupled to a capacitor. The gate driver includes a timing control circuit and a switch unit. The switch unit is coupled to the timing control circuit, the capacitor and a working voltage. The timing control circuit receives an input control signal and performs a timing control to the input control signal to generate a first control signal and a second control signal. The switch unit includes a first switch element and a second switch element. The second switch element controls a body voltage of the first switch element according to the second control signal. The switch unit enables the working voltage to charge the capacitor via the switch unit according to the first control signal and the second control signal.
