General Description

The NJU2102A is a system reset IC with watchdog timer to detect the abnormal conditions, such as shutdown of all supply voltages at once, or sudden voltage down and then generate the reset signal. It is possible to direct replacement from NJM2102. Furthermore, it improves usability by extending operating temperature, standardizing AC characteristics, and making each parameter highly accurate.
