Note:
Stresses greater than those listed under MAXIMUM RATINGS may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability.

The PT7M7825 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-up, powerdown and brownout conditions for P system;
2. Detecting power failure or low-battery conditions with a 1.25V threshold detector;
3. Watchdog functions;
4. Manual reset.
