Abstract

PURPOSE: To simplify and miniaturize a circuit constitution by providing a control transistor to send out a protecting signal from the voltage between the collector and the emitter when a sudden change occurs in the supplied voltage, which makes it possible to provide this circuit only in a power circuit required to be protected.
