SYSTEM RESET IC

■ GENERAL DESCRIPTION

The NJM2102 Possesses two functions. One is to detect a voltage

which decays from the desired voltage and generate a warning signal.

And also, the NJM2102 holds the warning signal for a certain term

after the specified voltage is obtained or recovered. The other one

(Watch Dog Timer) is to identify missing clocks of microprocessors.

Therefore, it should be said that the NJM2102 is ideal to protect any

microprocessors from the fales operations induced by undesired

condition.
