The PT7A751X/752X/753X family microprocessor(µP) supervisory circuits are targeted toimprove reliability and accuracy of power-supplycircuitry in µP’s systems. These devices reduce thecomplexity and number of components required tomonitor power-supply and battery functions.The main functions are:1. Asserting reset output during power-up, power downand brownout conditions for µP system.2. Detecting power failure or low-batteryconditions with a 1.25V threshold detector.3. Watchdog functions (not for PT7A753x)
