ABSTRACT:
A driver circuit for a large capacity switching element like power transistors etc. having an overdrive function. The driver circuit supplies a sharp overdrive current only at the build-up time and the control thereafter is effected by a constant current source so that the current limiting resistor can be saved and the current capacity of the various elements may be decreased.
