CS9803 Infrared Induction Control IC

CS9803 Infrared Induction Control IC 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 pass.

CS9803 Features
