Abstract
An apparatus and method for safely handling asynchronous shutdown of pulsewidth modulated output. A shutdown circuit controls asynchronous shutdown of a pulsewidth modulated stage to ensure that pulsewidth modulated signals of less duration than a minimum period does not occur at transition edges of the pulsewidth modulated signal, in which such short pulses may affect the proper operation of output circuitry.
