Power-Voltage Monitoring IC with Watchdog Timer

Cypress Semiconductor 

MB3793-42

Power-Voltage Monitoring IC with

Watchdog Timer

Description

The MB3793 is an integrated circuit to monitor power voltage; it incorporates a watchdog timer.

A reset signal is output when the power is cut or falls abruptly. When the power recovers normally after resetting, a power-on reset

signal is output to microprocessor units (MPUs). An internal watchdog timer with two inputs for system operation diagnosis can provide

a fail-safe function for various application systems.

The model number and package code are as shown below.

Model No.
