PT7M823/824/825 μP Supervisor Circuits Description Pin Assignments NEW PRODUCT 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.
