Abstract

A power-up detector for detecting power-up and power supply voltage bump conditions comprising a current mirror connected to a power supply, a pair of series connected resistors connected between the current mirror and ground, and providing a bias point at a junction of the series connected resistors, and a field effect transistor having a source-drain circuit connected between the current mirror and ground for providing an output signal, the transistor being controlled by the bias point.
