MB3793-42 - POWER-VOLTAGE MONITORING IC WITH WATCHDOG TIMER

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: ±2.5% Detection voltage with hysteresis Low power dispersion: ICC = 27 µA (reference) Internal dual-input watchdog timer Watchdog timer halt function (by inhibition terminal) Independently-set watchdog and reset times Mask option for detection voltage (4.9 to 2.4 V, 0.1-V steps) s.

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. There is also a mask option that can detect voltages of 4.9 to 2.4V in 0.1-V steps. The model number and package code are as shown below. Model No. MB3793-42 Package code 3793-A Detection voltage 4.2 V DataSheet4U.
