Introduction
The PT7M7xxx 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
