Filed:
Apr 17, 2000
Appl. No.:
9/550679

Abstract:
A power on reset cell is disclosed capable of accommodating faster power cycling rates and providing better trip point control. When the input supply voltage ramps up, the output of the power on reset cell transitions when the input is greater than a predetermined value. The power on reset cell includes a discharge circuit that is capable of discharging a subcircuit of the power on reset cell when the input supply voltage ramps down so that the output of the power on reset cell is prevented from prematurely transitioning during a subsequent ramping up of the input due to any latent charge accumulated in the prior ramping up cycle. The discharge circuit allows the power on reset cell to undergo faster power cycling without providing an invalid output. Furthermore, the discharge circuit provides better control of the output trip point. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other researcher to quickly ascertain the subject matter of the technical disclosure.
