Description
The PT7M78xx 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-up,
power-down and brownout conditions for
µP
system.
2. Detecting power failure or low-battery
conditions with a 1.25V threshold detector.
3. Watchdog functions
4. Manual reset.

Note1):
Threshold voltage=4.38V can be applied to all parts except PT7M7803/09/10M. PT7M7803/09/10M’s threshold voltage
is 4.26V.
2): Threshold voltage=2.25V only for PT7M7823/24K.
