| MOSDESIGN SEMICONDUCTOR CORP. PIR CONTROLLER M7616 DC PIR CONTROLLER GENERAL DESCRIPTION The M7616 is a low power PIR ( passive infra-red ) controller LSI designed for battery powered can be used in many application. The chip contains operation amplifiers, comparators, timer ,a voltage regulator, 2 oscillator and control circuits. An CDS device is installed externally to cut off the operation of M7616 during the day time. FEATURES High noise immunity. Low stand-by current < 50A @3.0V RELAY Driver only. Adjustable play on duration and latch duration. CDS input conditionally. 16 pin DIP or SOP package. APPLICATIONS PIR light controller, Motion Detector, Alarm system, Auto-door bell.
