CS9803 GENERAL DESCRIPTION CS9803 is a PIR (passive infra-red) controller, using analog mixing digital design technique and manufactures by CMOS process which can either drive TRIAC or RELAY depending on users' choice. With special noise immunity technique, CS9803 is the most stable PIR 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. CS9803 PIN DESCRIPTION Pin No. Pin Name I/O Description

1 UOU1 First stage OP amp output

2 NII 1 First stage OP amp positive input

3 II 1 First stage OP amp negative input

4 VREF Stable reference voltage

5 G N D System ground

6 TB Time base for 1. The delay time of receiving PIR singnal to sent a puls to trigger TRIAC or a high signal to trigger relay. The delay time = R x C x 32. The PIR signal patented and accepted only if the signal cycle greater than R x C x 768 .When state of relay or TRIAC is changing form active into inactive mode. It takes more than R x C x 4069, then system is able to receive PIR signal again. 2.The flash cycle show the beginning of auto mode. Note: Width of TRIAC pulse = R x C x 2. Flash cycle: R x C x 32768 10 K < R < 1M Ohm 100pF < C < 0.1 Uf (Reference Diagram 1)

7 QTEST For testing only

8 TCI To set up the timing of how long Triac or relay is active. During the period, if the system receives the PIR signal, then it restarts counting the timing again. The range f o r R : 1 0 K < R < 1 M O h m C : 1 0 0 u F < C < 0 . 1 u F ( R e ference Diagram 9 CDS Connected to a CDS for inhibiting relay or TRIAC being triggered. If TRIAC or relay has already being triggered by PIR signal and turned into active mode, then CDS can not inhibit PIR again. 10 TRIAC To trigger TRIAC, active low Sink current: 15 mA max. 11 RELAY To drive relay, active high Sink current: 10 mA max. Source current: 10 mA max. 12 ZCD Detect zero cross of AC line under remote mode function.

13 VDD Operation voltage: 5V, stand by current: 1mA
