CS9803 PIR CONTROLLER
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.

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
for R: 10K < R < 1M Ohm
C: 100uF< C < 0.1 uF (Reference Diagram
2)
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
13 VDD
14 II2
Detect zero cross of AC line under remote mode function.
Operation voltage: 5V, stand by current: 1mA
