ABSTRACT:
A system and method can mitigate voltage fluctuations. According to one embodiment, a delay system provides a delayed version of a first reference signal as a function of a supply voltage. A comparator provides a control signal for controlling a protection device based on the delayed version of the first reference signal and a second reference signal. The amount of delay provided by the delay system defines a threshold based on which the comparator provides the control signal.
