Abstract
A novel supply discriminator circuit is disclosed for detecting the level of a supply voltage during power-up of a system for configuring an integrated analog circuit such as a PCMCIA card. The circuit compares a reference voltage with a divided down supply voltage and latches the result a predetermined delay later. The delay thus provides timing for the supply voltage to stabilize after power-up to assure accurate detection, as well as noise immunity from other devices.
