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.

Infineon´s XENSIVTM TLE4966-2G is an integrated circuit dual Hall-effect sensor designed specifically for highly accurate applications. Precise magnetic switching points and high temperature stability are achieved by active compensation circuits and chopper techniques on chip. The sensor provides two independent speed outputs at Q1 and Q2 with the status (high or low) corresponding to the magnetic field value at the respective Hall element H1 and H2. Both Hall elements have the identical thresholds for BOP and BRP (BOP1 = BOP2 and BRP1 = BRP2). For positive magnetic fields (south pole) exceeding the threshold BOP1 and/or BOP2 the corresponding output Q1 and/or Q2 is low, whereas for negative magnetic fields (north pole) lower than BRP the output switches to high. Due to the spatial distance of the two Hall elements on the chip (d = 1.45mm) the two output signals will show a phase difference in case the sensor is used with a rotating magnetized pole wheel.

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.

Our new XENSIVTM TLI4966G Hall sensor is a double Hall switches with two output pins for applications with a rotating pole wheel. The sensor provides a speed and direction signal at the interface pins. This information can be directly used to realize a robust index counting system for anti-pinch prevention.The standard solution for index counting is realized by two Hall Latches. The TLI4966G comprises two integrated Hall plates enabling a small and cost effective system with only one sensor.The fixed distance of the Hall plates ensures the optimal solution to cancel out mounting uncertainties and reduces overall system tolerances. The built in direction detection is reliable and provides with each index step a valid direction signal. Additional development of algorithms for direction detection becomes obsolete.The speed and direction signals of the XENSIV™ TLI4966G can be fed directly into the capture/compare unit of a standard µController. This ensures a fast and easy system set up. The speed signal comes directly from the two integrated Hall elements, while the direction detection is calculated by a µController. The monolithic solution ensures minimal tolerances and a highly reliable system.A lot of index counting sensors operate at remote locations. The TLI4966G family is equipped with robust supply and I/O pins that allows system designers to realize remote sensor modules with a minimum of additional hardware components.
