Allegro MicroSystems, LLC introduces a new optimized Hall-effect integrated circuit (IC) and rare-earth pellet combination that provides a user-friendly solution for direction detection and true zero-speed, digital gear-tooth sensing. The small package can be easily assembled and used in conjunction with a wide variety of gear-tooth-sensing applications. This new IC employs patented algorithms for the special operational requirements of automotive transmission and recreational vehicle applications. It is also compatible with non-automotive applications found in white goods, exercise, and industrial equipment.
The speed and direction of the target are communicated through a variable pulse-width output protocol. The ATS699 is particularly adept at handling vibration without sacrificing maximum air gap capability or creating any erroneous “direction” pulses. Even higher angular vibration caused by engine cranking is completely rejected by the device. The advanced vibration detection algorithm will systematically calibrate the sensor IC on the initial teeth of true target rotation and not on vibration, always guaranteeing an accurate signal in running mode. Advanced signal processing and innovative algorithms make the ATS699 an ideal solution for a wide range of speed and direction-sensing needs.
Allegro’s ATS699 is available in a lead (Pb) free 3-pin SIP (suffix SN) package with a tin-plated leadframe.
