PIR Sensor Interface IC controls any type of AC load.
June 25, 2009 -
Designed to drive latching relay, LS6506R can be used in Wall Switch configuration (no Neutral) to enable full AC Mains cycle to be applied across any load. Also available, LS6507R drives triac in series with load and is suitable for use in lower-cost Wall Switch configuration for driving incandescent lamp loads. ICs can be used to manually or automatically switch loads on/off, and feature is offered where lights can be manually switched off and remain so while motion is detected.

Versatile PIR Interface IC Controls any Type of AC Load
LSI/CSI introduces the LS6506R, a step forward in PIR Sensor Interface ICs. Since the LS6506R is designed to drive a latching relay, according to Pete Visconti, VP Sales and Marketing, a huge advantage is gained by our customers in that it can used in a Wall Switch configuration (no Neutral available) to enable the full AC Mains cycle to be applied across any load rendering the Wall Switch suitable for driving all types of resistive and inductive loads including incandescent lamps, fluorescent lamps, electronic and magnetic transformers, motors, etc. Products incorporating the LS6506R produce energy savings in commercial and home applications. A sister chip, the LS6507R, drives a triac in series with the load and is suitable to be used in a lower cost Wall Switch configuration for driving incandescent lamp loads.
For home and commercial occupancy sensor applications, the ICs can be used in Wall Switch configurations to manually or automatically switch loads on and off. For commercial applications, a feature is offered where the lights can be manually switched off and will remain off as long as motion is detected allowing for uninterrupted Power Point Presentations, etc.
Other features include:
Five timeout selections ranging between 30 seconds and 30 minutes.
Three operating modes.
On chip voltage regulator for reliable performance.
PIR sensitivity adjustment.
Ambient light override control.
LED indication for motion detection.
50Hz/60Hz operation.
LS6506R and LS6507R are available in 16-Pin SOIC Narrow Body and DIP packages.
Pricing in 1k units is $0.75.
