A circuit includes comparator circuitry to sense a current through a load and compare the intensity of the current with a comparison threshold which can be set to a first, lower threshold value and a second, higher threshold value. Logic circuitry receives from the comparator circuitry a comparison signal having a first value or a second value based on whether the intensity is lower or higher than the comparison threshold. The logic circuitry is configured to assert a first overcurrent event signal or a second overcurrent event signal based on the comparison signal having the first value or the second value and the comparison threshold set to the first or second threshold value.
