ATS699LSN: Two-Wire, Differential, Vibration-Resistant Sensor IC with Speed and Direction Output

The ATS699LSN is an 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.

The IC employs patented algorithms for the special operational requirements of automotive transmission applications. 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. 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.

This device is available in a lead (Pb) free 3-pin SIP package with tin-plated leadframe.
