Discription
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 complexity and number of
components required to monitor power-supply and battery
functions.
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 (not for PT7A753x).
Applications
• Power-supply circuitry in P systems
