DESCRIPTION
The PT7A751X/752X/753X family microprocessor (P) supervisory circuits are targeted to improve reliability and accuracy of power-supply circuitry in P’s systems. The main functions are: 1. Asserting reset output during power-up, power- down and brownout conditions for P system. 2. Detecting power failure or low-battery conditions with a 1.25V threshold detector. 3. Watchdog functions...
