Product Details

Allegro’s diverse selection of speed sensor ICs provide optimized solutions for many non-automotive applications where speed or speed and direction information are needed. These sensor ICs can handle designs using various target geometries, materials, and sensing orientations. Allegro’s portfolio of speed sensor ICs contains solutions able to address requirements for applications needing both high and low frequency operation, detection of rotational direction, and small signals operation. Allegro's solutions offer over two decades of specific IC design advancements. These sensor ICs also incorporate lessons learned through our close work in automotive applications where many unique operational issues have been discovered and resolved through algorithm advancements. Allegro’s industry leading algorithms provide optimized performance for both two-wire, current source, and three-wire, open drain output protocols

The ATS468 is a true zero-speed gear tooth sensor IC consisting of an optimized Hall IC and a permanent magnet pellet configuration in a single overmolded package. The integrated circuit provides a manufacturer-friendly solution for digital gear tooth sensing applications. This small package can be easily assembled and used in conjunction with gears of various shapes and sizes.The integrated circuit incorporates dual Hall effect elements with a 2.2 mm spacing and signal processing that switches in response to differential magnetic signals created by a ferromagnetic target. The circuitry contains a sophisticated digital circuit to reduce system offsets, to calibrate the gain for air-gap-independent switchpoints, and to achieve true zerospeed operation. Signal optimization occurs at power-on through the combination of offset and gain adjust, and is maintained throughout the operating time with the use of a running-mode calibration. The running-mode calibration provides immunity to environmental effects such as micro-oscillations of the target or sudden air gap changes.The device is ideally suited to obtaining speed and duty cycle information in gear tooth-based speed, position, and timing applications, such as in speedometers.The ATS468 is available in two 4-pin SIPs (suffix SG and SJ). The packages are lead (Pb) free, with 100% matte tin leadframe plating
