ABSTRACT:
An apparatus for providing over current protection for a digital pulse width modulator is disclosed. The apparatus includes first logic circuitry for generating a primary interrupt indicating that a detected output current is greater than a threshold current. Second logic circuitry blanks out current spikes in the output current occurring on a leading pulse edge of at least one of a plurality of outputs of the digital pulse-width modulator.
