NJM2102
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.
