Abstract
A gate driver includes a gate driving main circuit and a power sequence control circuit. The gate driving main circuit disposed between an operating voltage and ground is coupled to a first gate voltage and a second gate voltage. The operating voltage is higher than ground and first gate voltage is higher than second gate voltage. The power sequence control circuit includes first-type transistors, a second-type transistor, a transistor and a judging circuit. The first-type transistors are coupled in series between first gate voltage and a first node and their gates are coupled to a second node. The second-type transistor is coupled between first node and second gate voltage and its gate is coupled to second node. The transistor is coupled between first gate voltage and gate driving main circuit and its gate is coupled to first node. The judging circuit generates an output signal to second node.
