MB3773 generates the reset signal to protect an arbitrary system when the power-supply voltage momentarily is intercepted or decreased. It is IC for the power-supply voltage watch and “Power on reset” is generated at the normal return of the power supply. MB3773 sends the microprocessor the reset signal when decreasing more than the voltage， which the power supply of the system specified， and the computer data is protected from an accidental deletion. In addition， the watch-dog timer for the operation diagnosis of the system is built into， and various microprocessor systems can provide the fail-safe function. If MB3773 does not receive the clock pulse from the processor for a specified period， MB3773 generates the reset signal.
