MB3793-27A
Power Voltage Monitoring IC with
Watchdog Timer
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 application systems.
Features
 Precise detection of power voltage fall: 2.5%
 Detection voltage with hysteresis
 Low power dispersion: I_CC = 31 A (reference)
 Internal dual-input watchdog timer
 Watchdog-timer halt function (by inhibition pin)
 Independently-set watchdog and reset times
 Three types of packages (SOP-8pin : 2 types)
Application
 Arcade Amusement etc.
