CS9803

PDF Page Organizer - Foxit Software Semic● General Description CS9803 Infrared Induction Control IC The CS9803 is a passive infra-red controller, using analog mixing digital design technique and manufactures by CMOS process which can either driver TRIAC or RELAY depending on user’s choice. With special noise immunity technique, CS9803 is the most stable passive infrared controller you can find on the market. More than this, there are few components needed in its application circuit which can reduce material cost and increase competitive. Features Operating voltage: 4.5V～5.5V (DC) Operating current≤1mA CDS input Pulse output for TRIAC drive or level output for relay drive Built-in 2-stage operational amplifier Adjustable output on time duration On –chip regulator for PIR sensor Zero-crossing triggering Application: Home security system Auto light system for garden, garage, hallway, staircase, porch, bathroom, etc. Auto switch for ventilation fan Auto notice system for office, storage, etc. Package: DIP16 Absolute Maximum Ratings Supply Voltage：..............................................................................................................................................-0.3～6.0V Operating Temperature： ...............................................................................................................................-25～+70℃ Input Voltage：................................................................................................................................-0.5～（VDD+0.5）V Storage Temperature： ................................................................................................................................-55～+150℃ Power Dissipation： .............................................................................................................................................. 500mW Pin Description 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 I/O O I I O P I I I I O O I P I I O Function Description First stage OP amp output First stage OP amp positive input First stage OP amp negative input Stable reference voltage System ground System clock Test only To set up the timing of how long Triac or relay is active Detect CDS TRIAC output RELAY output Detect zero cross Power ground Second stage OP amp negative input Second stage OP amp positive input Second stage OP amp output Vol: 2004-01 2004-12-28 1/2 PDF Page Organizer - Foxit Software CS9803 Electrical Characteristics Symbol VDD IOP VREF IREF Avo IOL1 IOH1 IOL2 IOH2 Characteristic Supply voltage Operating current Stable voltage Source current of VREF Op amp pen loop gain TRIAC sink current TRIAC source current RELAY sink current RELAY source current （Ta=25℃，VDD=5.0V，VSS=0V） Test Condition --no load VOH=3.3V Min. 4.5 --2.8 200 ----50 ----- Typ. 5 --3.1 --60 --------- Max. 5.5 1 3.3 ----15 --5 5 Unit V mA V µA dB mA µA mA mA Application Circuit 1、 TRIAC Application 470k 12 ZCD 1M FUSE1 CDS 10uF 9 CDS VDD 13 470uF 5.1V BT136 600E 1M 1M 4.7k 0.01uF 100k RES2 100p TRIAC 10 330 8 TCI 7 QTEST 6 TB 4 VREF 100uF CS9803GP RELAY 11 0.01u/250V 47 100k PIR 47K 0.01uF 2 NII1 II1 UOU1NII2 II2 UOU2 3 1 15 14 330k16 1220k 47nF 47uF 15k 47nF-68nF 22uF GND 5 2k -220uF 2、 RELAY Application CDS 10uF 9 CDS ZCD 5.1V 2.4k 470uF 100uF 20V/1W RELAY 5.6k VDD 13 1M 1M 4.7k 3.3--10nF 100k RES2 100p 100uF TRIAC 10 8 TCI 7 QTEST 6 TB 4 VREF CS9803GP RELAY 11 47k 0.47uF 100 FUSE1 PIR 47k 10nF 2 NII1 II1 UOU1 NII2 II2 UOU2 3 1 15 14 330k 16 1220k 22uF 15k 47nF--68nF 47nF 47uF GND 5 0.047uF 2k -220uF 2/2
