General Description
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.
