TLE4966-3G
XENSIV™ - TLE4966-3G highly sensitive automotive Hall switch with direction detection
Infineon’s XENSIVTM TLE4966xG family are double Hall latches with two output pins for applications with a rotating pole wheel. Depending on product variant, the sensor provides either a speed and direction signal or two speed signals related to the switching of the two Hall elements. This information can be directly used to develop a robust index counting system for anti-pinch prevention.
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.
