A driver circuit drives a power element connected to an inductive load. The driver circuit includes an input terminal coupled to a control terminal of the power element through a trigger block, and a voltage regulator block having a circuit node coupled to a first supply voltage reference, as well as to a second supply voltage reference through a capacitor. A voltage comparator stage includes an operational amplifier having an inverting input connected to the circuit node and a non-inverting input is connected directly to a terminal of the power element, such as to the emitter terminal thereof. The operational amplifier also includes an output connected to the control terminal of the power element.
