Abstract
A monolithically integratable control circuit for the switching of inductive loads, have a push-pull output stage formed by transistors each having their base terminal connected to a control circuit and to a charge extraction transistor driven to conduct at saturation in phase opposition with respect to the output transistor to which it is connected. This charge extraction transistor has its base terminal connected via a diode to the control circuit and to a biasing resistor.
