Power Voltage Monitoring IC
with Watchdog Timer
MB3793
-37A
I
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 fall-safe function for various applicaiton systems.
There is also a mask option that can detect voltages of 4.9 to 2.4 V in 0.1-V steps.
The model number is MB3793-37A corresponding to the detected voltage. The model number and package code
are as shown below.
