Abstract
A control circuit for an inductive load driver includes a control block activated by a trigger signal and an output coupled to the control terminal of a power element. The control circuit includes an auxiliary current generator capable of delivering a current that is added to the current provided by control block and the sum of these currents is provided to the control terminal of the power element. The auxiliary current generator enables the inductive load driver to operate normally even though the trigger voltage is less than an optimal voltage value.
