| Rato Description: RT1072 RT1072 is a PIR(Passive Infra-Red)controller,The PIR controller can sense the motion movement and activate the electronic application. The interstracture of the PIR controller IC is using The analog mixing digital technique to design,It is proven to be very stable in any circumstances. It can be either drive TRIAC or RELAY depending on users' ChoiceC The application circuit is very cost effectiveC Features : Mixed-ModeE COMS IC. High noice immunity. Constant current CDS input. PIR input. Adjustable output duration. Drive either RELAY OR TRIAC. Pin Out : Absolute Maximum Rating: Symbol Parameter VDD Supply voltage VI Input voltage VO Output voltage Pdis Max.
