μP Supervisor Circuits
Features
Description
The PT7A751X/752X/753X family micro-
processor (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)
