Abstract
A control circuit for controlling the operation of a main switch device which manages an electrical current delivered to an inductive load device, the control circuit including: a current sense circuit configured to be coupled to the switch device and to output a signal representative of an electrical current through the inductive load device; a current comparator circuit configured to receive an actuation command signal, compare the signal representative of the electrical current through the inductive load device with a signal representative of a predetermined current, and to output a control signal based on the comparison for controlling the operation of the main switch device when the actuation command signal indicates that the inductive load device is to be activated; and a recirculation circuit configured to recirculate current through the inductive load device, such that the current used to activate the inductive load device is selectively provided by the main switch device and the recirculation circuit.
