Overview
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.
The model number and package code are as shown below.
Model No.
