Voltage monitor for power-fail or low battery warning
Guaranteed RESET/RESET valid at V
CC
= 1.2V
Description
The PI4S70xxx/PI4S813L 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-μp, power-down and
brownout conditions for μP systems.
2. Detecting power failure or low-battery conditions with a
1.25V threshold detector.
3. Generating an independent watchdog output that goes low if
the watchdog input has not been toggled within 1.6 seconds.
4. Asserting reset output with an active-low manual-reset input
