CS9803
Infrared Induction Control IC
General Description
The CS9803 is a p assive 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 i nfrared controller you can find o n the
market. More than thi s, there a re few components nee ded in i ts application circuit which can reduce material cos t and
increase competitive.
