POWER-VOLTAGE MONITORING IC

WITH WATCHDOG TIMER

MB3793-45

■ 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.

Model No.
