Claim 17:
18. The driver system of claim 1, wherein the overcurrent monitoring circuit comprises:
a current sensor configured to generate the measurement signal representative of the load current;
a comparator configured to compare the measurement signal to the comparator threshold and generate an overcurrent detection signal while the measurement signal exceeds the comparator threshold;
a first deglitch filter configured to receive the overcurrent detection signal and generate the first fault signal on a condition that the first deglitch filter receives the overcurrent detection signal for an entire duration of the first time interval; and
a second deglitch filter configured to receive the overcurrent detection signal and generate the second fault signal on a condition that the second deglitch filter receives the overcurrent detection signal for an entire duration of the second time interval.
