PT7A7523 Overview
The PT7A751X/752X/753X family microprocessor (P) supervisory circuits are targeted to improve reliability and accuracy of power-supply circuitry in P’s systems. These devices reduce the plexity and number of ponents required to monitor power-supply and battery functions. Asserting reset output during power-up, power- down and brownout conditions for P system.
