Discription
The PT7M7xxx family microprocessor (
P) supervisory
circuits are targeted to improve reliability and accuracy
of power-supply circuitry in
P 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
P 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
P systems
