Abstract:
In an embodiment a circuit includes drive circuitry configured to be coupled to a control terminal of an electronic switch and configured to apply a discharge signal to the control terminal causing the electronic switch to become conductive and provide an electrical discharge path for an energized element, a sensing node configured to be coupled to the control terminal and configured to sense a voltage at the control terminal and a feedback network coupled between the sensing node and the drive circuitry, wherein the feedback network includes a comparator circuit coupled to the sensing node and configured to compare the voltage at the control terminal and sensed at the sensing node with a reference threshold and to provide a comparison signal having a first value and a second value, respectively, in response to the voltage at the control terminal being higher or lower than the reference threshold, and wherein the drive circuitry is configured to produce the discharge signal as a function of the comparison signal.
