Description
The MB3793 is an integrated circuit to monitor power voltage; it incorporates a watchdog timer. A reset signal is output when the power supply voltage is cut or falls instantaneously. When the power supply recovers normally after resetting, a power-on reset signal is output to monitor the power supply voltage. A built-in watchdog timer with two inputs for system operation diagnosis can provide a fail-safe function for various application systems.

Features
■ Precise detection of power voltage fall: ± 2.5%
■ Detection voltage with hysteresis
■ Built-in dual-input watchdog timer
■ Watchdog timer halt function
■ Independently-set watchdog and reset times
■ Open drain output
■ Package : SOP

Applications
    The MB3793 has various uses such as the amusement devices.
