MB3793-30A
Power Voltage Monitoring IC with
Watchdog Timer Datasheet
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: ICC = 31 μA (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.
