UT8803

UNISONIC TECHNOLOGIES CO., LTD UT8803 PIR INFRARED REMOTE CONTROL CIRCUIT CMOS IC „ DESCRIPTION The UTC UT8803 is an integrated circuit that design for infrared PIR controlling. It needs only few external components in application circuit. It can be applied as controller of light, electric switching and burglar alarm, and so on. „ FEATURES * High Noise Immunity. * Output drivable RELAY or TRIAC. * Contain two OP amps, gain adjustable. * Control time adjustable. * Steady voltage inside output 3.1 V to drive the PIR directly. * Integrate zero cross detect, the AC power supply triggers synchronously, lowering the power supply pollution. „ ORDERING INFORMATION Ordering Number Lead Free Halogen Free UT8803L-D16-T UT8803G-D16-T Package DIP-16 Packing Tube www.unisonic.com.tw Copyright © 2009 Unisonic Technologies Co., Ltd 1 of 6 QW-R502-094,B UT8803 „ PIN CONFIGURATION UOU1 NII 1 II 1 VREF GND TB QTEST TC1 1 2 3 4 5 6 7 8 16 UOU2 15 NII 2 14 II 2 13 VDD 12 ZCD 11 RELAY 10 TRIAC 9 CDS „ PIN DESCRIPTION PIN NO. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 PIN NAME UOU1 NⅡ1 Ⅱ1 VREF GND TB QTEST TCI CDS TRIAC RELAY ZCD VDD Ⅱ2 NⅡ2 UOU2 First stage OP amp output FUNCTION First stage OP amp positive input First stage OP amp negative input Reference voltage Ground Time base for System Clock.
