Allegro MicroSystems has launched a new three-wire differential speed sensor chip which integrates EMI protection and back bias magnet for zero-speed operation. The ATS668 is designed for automotive transmission systems and also ideal for non-automotive applications such as recreational vehicles, industrial equipment, white goods, and exercise equipment.
The device is offered in a small single over-mold package that can be easily assembled and used in conjunction with a wide variety of gear tooth sensing applications.
A dual element Hall chip inside the device switches in response to differential magnetic signals created by a ferromagnetic target.
The chip also contains a sophisticated compensating circuit designed to eliminate the detrimental effects of magnet and system offsets.
The device is available in a lead (Pb) free 3-pin SIP package (SM) with matte-tin leadframe plating.
