Patent abstract
A circuit for monitoring a PWM signal and providing an output indicating a condition of the PWM signal. The circuit also uses condition based hysteresis to maintain an output value at a previous state until the condition of the PWM signal has remained unchanged for a given duration. In addition, the circuitry may be used in conjunction with a switching regulator to reduce switching noise during high duty cycle operation.
