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. Precision supply-voltage monitor- 4.63V (PT7A7511, 7521, 7531)- 4.38V (PT7A7512, 7522, 7532)- 3.08V (PT7A7513, 7523, 7533)- 2.93V (PT7A7514, 7524, 7534)- 2.63V (PT7A7515, 7525, 7535)\n200ms reset pulse width\nDebounced TTL/CMOS-compatible manual reset input\nIndependent watchdog timer 1.6sec time-ou;
