| bq O@ 1/2- |/ NeAE3/4 PIR CONTROLLER MOSDESIGN SEMICONDUCTOR CORP. M7615 DC PIR CONTROLLER GENERAL DESCRIPTION \aO-z The M7615 is a low power PIR ( passive infra-red ) controller with hi level output , paired with M3766 for battery power door bell/ relay /alarm application. With special noise immunity technique , M7615 is the most stable PIR 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. FEATURES ~So E High noise immunity. E Low stand-by current < 90uA E Drive either Relay. E Adjustable play on duration and latch duration. E On-chip voltage regulator. E 20 second warm-up. E CDS input conditionally. E 14 pin DIP or SOP package. APPLICATIONS ~AI E PIR light controller , Motion Detector , Alarm system , Auto-door bell.
