No Preview Available ! 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. ■ PACKAGE OUTLINE NJM2102D (DIP8) NJM2102M (DMP8) ■ FEATURES ● Internal Watch Dog Timer ● Precise Detection of Supply Voltage Down ● Package Outline ● Bipolar Technology (4.2V ±2.5%) DIP8, DMP8, SIP8 NJM2102L (SIP8) ■ PIN CONFIGURATION NJM2102D NJM2102M NJM2102L ■ BLOCK DIAGRAM PIN FUNCTION 1.
