Power Voltage Monitoring IC  
with Watchdog Timer  
MB3793-37A  
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.  
Model No.

FEATURES  
• Precise detection of power voltage fall: ±2.5%  
• Detection voltage with hysteresis  
• Low power dispersion: ICC = 30 µA (reference)  
• Internal dual-input watchdog timer  
• Watchdog-timer halt function (by inhibition pin)  
• Independently-set wacthdog and reset times
