Overview
MOSDESIGN SEMICONDUCTOR CORP.
DC PIR CONTROLLER PIR CONTROLLER M7616 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 < 50μA @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.
