General Description

The NJU2103A 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. It is possible to direct replacement from NJM2103 and the small TVSP8 package is added. Furthermore, it improves usability by extending operating temperature, standardizing AC characteristics, and making each parameter highly accurate.
