Abstract

A driver circuit for a solid-state relay which includes a split power supply. The positive supply of the split power supply provides a voltage for application to the gate of a power FET for supplying power to a load. The negative supply of the split power supply provides a negative voltage for turning off a control transistor. The control transistor prevents the power FET from conducting power to the load when the driver circuit is turned off. The circuit is particularly adapted for driving a power GaN FET solid state relay. The circuit is provided in a cascaded embodiment to increase the blocking voltage of the solid-state relay.
