M7621 - PIR CONTROLLER

General Description

The M7621 integrated circuit combines all required functions for a single chip Passive Infra Red (PIR) light controller.

It is designed for load switching with a transistor or a relay in 3 wire AC and DC systems.

A conventional PIR sensor connects directly to the PIR input.

Key Features

  • ‧ Digital signal processing ‧ Temperature compensation input ‧ Adjustment brightness. ‧ Adjustable PIR sensitivity ‧ Adjustable output turn-on time ‧ Retrigger / Non-retrigger function ‧ Dimmer function ‧ PWM output ‧ RELAY output ‧ SOP-16 package.

MOSDESIGN SEMICONDUCTOR CORP. PIR CONTROLLER FOR DC/AC APPLICATIONS PIR CONTROLLER M7621 DESCRIPTION The M7621 integrated circuit combines all required functions for a single chip Passive Infra Red (PIR) light controller. It is designed for load switching with a transistor or a relay in 3 wire AC and DC systems. A conventional PIR sensor connects directly to the PIR input. The pull-down resistor and DC decoupling circuitry are integrated on chip. The PIR signal is converted to a 15 bit digital value. External potentiometers or resistors are used to set the operating parameters for sensitivity, on-time, brightness, fade, CDS sensor and environment temperature correction.
