Introduction
The STCxxx family microprocessor (µP) supervisory circuits are targeted to improve reliability and accuracy of power-supply circuitry in µP systems. These devices reduce the plexity and number of ponents required to monitor power-supply and battery functions. The main functions are: 1. Asserting reset output during power-up, powerdown and brownout conditions for µP...
