Push-pull Reset output and SOT23-3 supervisory IC

Product Description

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.
