DRV5023: Camshaft Sensor use DRV5023

Hello Tony,

Thank you for using the TI forum.

First off, I would like to recommend that you look into using an inductive sensor for this application, such as the LDC0851. This is a "Differentially Compensated and Highly Accurate Inductive Switch" that is particularly well-suited for gear tooth counting (without the need of a magnet). If you have more questions on how this would work, you can click "Ask a related question" and make sure to put in the new relevant part number (LDC0851).

As for your question, it can be possible to use the DRV5023, but it significantly depends on many factors, including your physical setup, magnet, and gear teeth spacing and height. I recommend simulating your setup with a tool such as FEMM (available for free at: http://www.femm.info) to see if this sensor will work for you (specifically checking to make sure that Brp and Bop will be crossed).

If the DRV5023 does not work for your setup, you could use a linear device, such as the DRV5056 or the DRV425.
