Original question:

DRV5056-Q1: Head on linear measurement

DRV5056-Q1: Distance measurement

Hi,

The TI tool takes into consideration d1 distance from the surface of the sensor IC for sensing of distance measurement.

Whereas, the sensing element is placed at 0.47mm inside the IC from the surface.

Do we need to take into account start of distance of measurement as (0.47mm + d1) while designing or should be considered from surface of IC?

Thank You.

    Hello Prathmesh,

    Thanks for posting to the sensors forum! We have a new simulation tool online that is more accurate and can help you with simulations as well as device emulation. It still does not have all the devices, variants, and features up as we are still working on development but you may find the features we currently offer more helpful: https://webench.ti.com/timss/

    The TIMSS tool will eventually take data in reference to the bottom of the package but at the moment it simulates just using the point in space that you specified so the sensor location would have to be manually configured in this current version.

    As for the Proximity Sense Tool, it does take into consideration the Hall-effect sensor location inside of the package using the top surface of the package as a reference. Meaning you would not need to include the 0.47mm from the top of the IC package to the sensor itself.

    Best,

    Isaac

    Thank you.

    But besides using the tool or not using the tool, by analytical calculation of Vout do we need to consider measurement from IC surface or not?

    Hello Prathmesh,

    Ideally you would want to take the case where the device is not on the surface and located in the sensor itself, doing this will help you achieve the most accurate calculation possible. This is why we try to get our tools to handle this for our users even though they may not pay attention to the sensors location inside the package. 

    Best,
