    Eric, we currently don't have a direct replacement for that device, but we do have some hall and inductive solutions that you may be able to leverage. May I know more about the nature of your application?

    One option I can readily think of is to use two of the DRV5055-Q1 placed 90° from each other around a rotating magnet, like this quick illustration I've done here:

    And if you call those sensors X and Y, then you can get voltages relative to the magnetic field intensity and direction as the magnet turns, that will end up looking something like this:

    The sin and cos waves can be used in an arctan equation to find the angle of the rotation magnet for all 360°

    We'll have an app note coming out soon that goes into more of the details of this application implementation.  Does that sound like something that will work for you?
