Introduction
The PT7A751X/752X/753X family microprocessor
(P) supervisory circuits are targeted to improve
reliability and accuracy of power-supply circuitry in
P systems. These devices reduce the complexity and
number of components required to monitor power-
supply and battery functions.
The main functions are:
1. Asserting reset output during power-p, 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 (not for PT7A753x).
Applications
Power-supply circuitry in P systems
