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 system; 2. Detecting power failure or low-battery conditions with a 1.25V threshold detector; 3. Watchdog functions; 4. Manual reset.
