ABSTRACT:
An electrical circuit for driving an inductive load includes an output transistor of one conductivity type and a detector transistor of the other conductivity type. The output transistor has an emitter connected to a power source, a base to which an input signal is supplied, and a collector connected to one end of an inductive load. The detector transistor has an emitter connected to the collector of the output transistor, a base connected to the other end of the inductive load, and a collector connected to the base of the output transistor. When the output transistor is rendered nonconductive, high counter electromotive force is induced between both ends of the inductive load. Thereby the detector transistor turns on and the output transistor is rendered conductive again.
