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.
