Abstract

PURPOSE:To increase the dielectric strength of an output stage circuit by providing a switch circuit to the base of the output-stage transistor (TR) of a Darlington circuit. CONSTITUTION:A Darlington circuit consists of TRs 21 and 23. A TR26 interposed between the TR23 and the ground turns on and off according to the inverted signal of an enable signal. The dielectric strength viewed from an output terminal OUT to the ground potential is the sum of the base-emitter dielectric strength of the TR23 and the collector-base dielectric strength of the TR26 when the base and emitter are short-circuited, so the dielectric strength is increased.
