PT7M7809STEX:

The PT7M78xx family microprocessor ( µP) supervisory circuits are targeted to improve reliability and accuracy of power-supply circuitry in µP 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. Detecting power failure or low-battery conditions with a 1.25V threshold detector. 

3. Watchdog functions 4. Manual reset.

Applications

 • Power-supply circuitry in µP systems
