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