The small package can be matched to a wide variety of gear-tooth-sensing applications. This IC employs algorithms adapted to 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 handles 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 suit the ATS699 for a wide range of speed and direction-sensing needs. It comes in a 3-lead SiP.
