    Scott Bryson said: TMAG5170 - ( 2 Ch. sample time is approx. 75 us. ) How this was calculated? 75us is high time compared to 10us of DRV5055. So looks like we cant use this TMAG5170 for high speed application, right? Does TI have any other linear sensor for…

  • TMAG5170: Off-axis magnetic angle sensing - how to maintain angle accuracy despite mechanical tolerances

    TI Thinks Resolved
    Part Number: TMAG5170 We are developing a device that uses a TMR sensor that is positioned in-plane (off-axis) with respect to a permanent magnet that is rotating about its center. We use a calibration protocol to map the orientation of the magnet to…

  • TMAG5170: TMAG5170

    Part Number: TMAG5170 Hello, we need to use this sensor with linear motor (linear door application) for sensing position for motor commutation and closed loop position/speed control. Used commutation is vector control(sinusoidal). Up to now, we use 3…

  • RE: TMAG5170: Assorted Power and Timing Questions

    Resolved
    Yes. The measured current remained constant for me for the duration of the state change delay, and then steps quickly to the final current. So switching from config mode to active mode, the current holds at the config mode level. When changing from active…
