The NJU2103B is a power supply voltage monitoring IC that instantaneously detects abnormality such as power supply voltage cutoff or drop and generates reset signal. It can monitor 2 systems of 5 V power supply and arbitrarily set voltage. Since VSB
Detecting Voltage, VSC
Detecting Voltage and RESETOutput Pulse Width are adjusted from NJU2103A, it is more suitable for replacement from MB3771. Furthermore, it improves usability by extending operating temperature, and making each parameter highly accurate.
