TLE4966V-1G
XENSIV™ - TLE4966V-1G in plane sensing with vertical dual Hall effect latch for automotive
The TLE4966V-1G is specifically designed to detect the rotation direction and the rotation speed of a pole wheel.The sensing direction is in-plane to the sensor surface. Even at high distances to the hall elements the direction will be detected correctly.
The two Hall plates realized on-chip ensure the optimal solution to cancel out mounting uncertainties and reduce overall system tolerances. Additional development of algorithms for direction detection becomes obsolete. The built in direction detection is reliable and provides with each index step a valid direction signal.
The speed and direction signals or the speed and speed signals of the TLx4966xG family can be fed directly into the capture/compare unit of a standard microcontroller. This ensures a fast and easy system set up. These signals come directly from the two integrated Hall elements. The monolithic solution ensures minimal tolerances and a highly reliable system.
