ABSTRACT:
A monolithically integratable control circuit for switching inductive loads, comprising a Darlington-type final stage, is described. The base of the Darlington control transistor is coupled to the collector of a transistor for extracting charge, the transistor conducting in phase opposition to the Darlington control transistor. The emitter of the transistor for extracting charge is coupled to the negative supply terminal and to the output terminal of the final stage, via a first and a second diode respectively.
