CS9803GP Infrared passive Induction Control IC, driver TRIAC or RELAY 
DataSheet
General Description
The CS9803GP Integrated Circuit (IC) is a passive infra-red controller, using analog mixing digital design technique and manufactured by CMOS process which can either drive TRIAC or RELAY depending on user's choice.
With special noise immunity technique, CS9803GP IC 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 competitiveness.
