Supervisor Circuits
Features
Description
The PT7M78xx 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.
