Description
The PT7A751X/752X/753X family microprocessor
(
P) supervisory circuits are targeted to improve
reliability and accuracy of power-supply circuitry in
P’s 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 (not for PT7A753x)
Applications
Power-supply circuitry in
P systems
