DRV5033: Technical Inquiry regarding DRV5033AJQDBZR

Hi, TI expert

We have a technical inquiry from a customer regarding DRV5033AJQDBZR.

Q1) I would like to ask whether the recognition timing or recognition location is different depending on the N pole and S pole.

Q2) 7.3.2 Looking at the contents, it seems that there is a difference in the timing of recognition of the N and S poles. Is that correct?

       In addition, if used at a distance where both the N and S poles are recognized, can there be a problem with the recognition timing?

inquiry about POWER ON TIME.

Q3) If you look at the 7.3.3 section, it seems that you can check the valid recognition point after recognizing the POWER ON TIME time Ton. Currently, after recognizing the DRV5033AJQLPG hall sensor, I am checking the location, but if I do not keep the POWER ON TIME time, will there be a difference in sensor recognition? (I wonder if it is necessary to keep the Power On Time.)

Q4) I would like to ask if there is a difference depending on the direction of the N and S poles when using it in a way that recognizes the position of the magnet while moving.

As shown in the image above, it is planned to be used in a way that the recognition position is confirmed while the magnet's position moves toward the sensor.

Looking at the data above, it seems that there is a difference between the N pole time and the S pole start, so please check.

Please check. Thank you.

    Hello Grady,

    Thank you for your patience on this thread while we were out of office for the holidays.

    Let me help address your questions above.

    1. I would like to ask whether the recognition timing or recognition location is different depending on the N pole and S pole.
      1. The timing and sensor are the same for both N and S poles, they share a single output so its not possible to differentiate if the field detected is a North or South magnetic field.

    2. 7.3.2 Looking at the contents, it seems that there is a difference in the timing of recognition of the N and S poles. Is that correct?

      1. This is not correct, figure 13 and 14 on section 7.3.2 is trying to indicate the expected behavior at power up when the magnetic field is larger than the operating threshold and when the magnetic field is below the release threshold. 

    3. In addition, if used at a distance where both the N and S poles are recognized, can there be a problem with the recognition timing?

      1. Can you indicate what you mean by this? I am not sure I understand.
    4.  If you look at the 7.3.3 section, it seems that you can check the valid recognition point after recognizing the POWER ON TIME time Ton. Currently, after recognizing the DRV5033AJQLPG hall sensor, I am checking the location, but if I do not keep the POWER ON TIME time, will there be a difference in sensor recognition? (I wonder if it is necessary to keep the Power On Time.)
      1. I am sorry I am not sure if I completely understood this question as well. But are you asking about the validity of data before the Ton time?
    5. I would like to ask if there is a difference depending on the direction of the N and S poles when using it in a way that recognizes the position of the magnet while moving.
      1. The DRV5033 does not provide a way to differentiate between N and S pole. If your application requires to determine the polarity of the magnetic field the sensor is experiencing I would recommend using a device like DRV5032, although this would only be possible in the X2SON package. Since being able to detect an additional output would require an additional pin. So the DU, DG, and FD versions in X2SON offer an extra output.

    Best,

    Isaac
