TMAG5233: Why is the variation for BOP and BRP so high? Is it possible to get these sensors with a tighter tolerance range?

Part Number: TMAG5233

Tool/software:

From the datasheet, BOP can vary from 1.6mT to 4.3mT, and BRP can vary from 0.6 to 3.5mT. Is there a way to obtain tighter tolerances?

    Hi Julien,

    Thanks for posting your question to the sensors forum and welcome to E2E.

    The BOP min/max and BRP min/max specs are provided to account for device variations across supply voltage and temperature. And best practice is to design the system around the BOP MAX and BRP MIN specifications to ensure the device will operate and release even in these corner cases.

    For an in-plane Hall-effect switch, the TMAG5233 has the best BOP/BRP tolerances we currently have to offer. The TMAG5231 and DRV5032 are available as Hall-effect switches sensitive to magnetic fields in the Z-direction (perpendicular to the top of the device package).

    Best regards,

    Jesse
