DRIVER CIRCUIT FOR A SEMICONDUCTOR POWER SWITCH

A driver circuit for controlling a semiconductor power switch comprises a first power driver transistor and a second power driver transistor complementary to the first power driver transistor. Both power driver transistors have an output terminal connected to an input terminal of the semiconductor power switch. An input terminal of the second power driver transistor is connected to a half bridge circuit comprising a first pre-driver transistor and a second pre-driver transistor complementary to the first pre-driver transistor. Both first and second pre-driver transistors have an output terminal connected to the input terminal of the second power driver transistor. This provides fast switching times with low power consumption for the pre-driver transistors.
