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 < 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.
