UNISONIC TECHNOLOGIES CO., LTD 81CXXX/81NXXX CMOS IC VOLTAGE DETECTORS WITH BUILT-IN DELAY TIME 3 1 2 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. 1 SOT-23 SOT-89 1 FEATURES TO-92 *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 µA (VIN=2.0V) *Pb-free plating product number: 81CXXXL/81NXXXL ORDERING INFORMATION CMOS: Order Number Normal Lead Free Plating 81Cxx-①-AB3-E-R 81CxxL-①-AB3-E-R 81Cxx-①-AE3-3-R 81CxxL-①-AE3-3-R 81Cxx-①-AE3-5-R 81CxxL-①-AE3-5-R 81Cxx-①-T92-D-B 81CxxL-①-T92-D-B 81Cxx-①-T92-E-B 81CxxL-①-T92-E-B 81Cxx-①-T92-D-K 81CxxL-①-T92-D-K 81Cxx-①-T92-E-K 81CxxL-①-T92-E-K ①:Delay Time Duration Code 1 ~ 50 ms 50 ~ 200 ms 200 ~ 400 ms P Q R Package SOT-89 SOT-23 SOT-23 TO-92 TO-92 TO-92 TO-92 Pin Assign. 1 2 3 O I G O G I G O I I G O O I G I G O O I G Packing Tape Reel Tape Reel Tape Reel Tape Box Tape Box Bulk Bulk N-Channel: Order Number ①:Delay Time Normal Lead Free Plating Duration Code 81Nxx-①-AB3-E-R 81NxxL-①-AB3-E-R 81Nxx-①-AE3-3-R 81NxxL-①-AE3-3-R 81Nxx-①-AE3-5-R 81NxxL-①-AE3-5-R H 1 ~ 50 ms J 81Nxx-①-T92-D-B 81NxxL-①-T92-D-B 50 ~ 200 ms 81Nxx-①-T92-E-B 81NxxL-①-T92-E-B 200 ~ 400 ms K 81Nxx-①-T92-D-K 81NxxL-①-T92-D-K 81Nxx-①-T92-E-K 81NxxL-①-T92-E-K Note: 1.
