MB3793-34A
Power-Voltage Monitoring IC with
Watchdog Timer
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.
Model No.
