MB3793-30 - POWER-VOLTAGE MONITORING IC

Datasheet Summary

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).

Features

  • Precise detection of power voltage fall:.

FUJITSU SEMICONDUCTOR DATA SHEET To Top / Lineup / Index DS04-27402-2E ASSP POWER-VOLTAGE MONITORING IC WITH WATCHDOG TIMER MB3793-42/30 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. Two models with detection voltages of 4.2 and 3.0 V are available. There is also a mask option that can detect voltages of 4.9 to 3.0 V in 0.1-V steps. The model numbers are MB3793-42 or -30 corresponding to the detected voltage.
