Power Supply Monitor With Watch-Dog Timer

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 t 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.
