ABSTRACT:
A power edge detector includes a voltage divider, a pull-up circuit, and a cut-in pull-down circuit. The voltage divider receives and divides an input power voltage so as to generate a divided voltage. The pull-up circuit receives the input power voltage and transmits the input power voltage to an output terminal when the input power voltage does not exceed a predetermined threshold. The cut-in pull-down circuit is connected to the voltage divider and the pull-up circuit for pulling down the voltage level of the output terminal in response to the divided voltage when the input power voltage exceeds the predetermined threshold.
