Top Features


The ATS693LSG 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 assembled simply 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 ATS693 is particularly adept at handling vibration without sacrificing maximum air gap capability or creating any erroneous direction information. Even higher angular vibration caused by engine cranking is completely rejected by the device. The advanced vibration detection algorithm systematically calibrates 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 ATS693 an ideal solution for a wide range of speed and direction sensing needs.

This device is available in a lead (Pb) free 4-pin SIP package with a 100% matte tin plated leadframe.
