| UNISONIC TECHNOLOGIES CO., LTD 81CXXX/81NXXX VOLTAGE DETECTORS WITH BUILT-IN DELAY TIME DESCRIPTION The UTC 81CXXX and 81NXXX series are good performance voltage detector and manufactured by CMOS technologies with highly accurate, low power consumption. A delay circuit is built-in to each detector, therefore, peripherals are unnecessary and high density mounting is possible. Detect voltage is extremely accurate with minimal temperature drift. Both CMOS and N-channel open drain output configurations are available. 3 CMOS IC 1 1 2 SOT-23 SOT-89 1 FEATURES *Highly Accurate : Detect voltage 2% *Built-In Delay time : 1ms ~ 50ms, 50ms ~ 200ms, 200ms ~ 400ms, *Detect Voltage Temperature Characteristics: TYP 100ppm/ *Wide Operating Voltage Range : 0.7V ~ 10.0V *Low Current Consumption : TYP 1.0 A (VIN=2.0V) TO-92 *Pb-free plating product number: 81CXXXL/81NXXXL ORDERING INFORMATION CMOS: Order Number Normal Lead Free Plating 81Cxx- -AB3-E-R 81CxxL- -AB3-E-R 81Cxx- -AE3-3-R 81CxxL- -AE3-3-R 81Cxx- -AE3-5-R 81CxxL- -AE3-5-R 81Cxx- -T92-D-B 81CxxL- -T92-D-B 81Cxx- -T92-E-B 81CxxL- -T92-E-B 81Cxx- -T92-D-K 81CxxL- -T92-D-K 81Cxx- -T92-E-K 81CxxL- -T92-E-K N-Channel: Order Number :Delay Time Normal Lead Free Plating Duration Code 81Nxx- -AB3-E-R 81NxxL- -AB3-E-R 81Nxx- -AE3-3-R 81NxxL- -AE3-3-R 81Nxx- -AE3-5-R 81NxxL- -AE3-5-R H 1 ~ 50 ms J 81Nxx- -T92-D-B 81NxxL- -T92-D-B 50 ~ 200 ms 81Nxx- -T92-E-B 81NxxL- -T92-E-B 200 ~ 400 ms K 81Nxx- -T92-D-K 81NxxL- -T92-D-K 81Nxx- -T92-E-K 81NxxL- -T92-E-K Note: 1.
