The PT7M823/824/825 family micro-processor (μP) supervisory circuits are targeted to improve reliability and accuracy of powersupply circuitry in μP’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 μP system.
2. Watchdog functions
3. Manual reset
