Abstract
An overcurrent detection circuit and method for one or more capacitive loads includes sensing current being supplied to the one or more capacitive loads to thereby generate a sensed current, and sensing a voltage rate of change across the one or more capacitive loads to thereby generate a differentiator output. The differentiator output is added to a fixed reference setpoint to thereby generate an overcurrent setpoint. The sensed current is compared to the overcurrent setpoint, and an overcurrent trip signal is supplied when the sensed current is greater than or equal to the overcurrent setpoint.
