DRV5055: temperature compensation coefficients min/MAX

Part Number: DRV5055

Hello Professional,

I have question for DRV5055's internal temperature compensation  coefficients.
Datasheet only explained 0.12%/C[typ] but it is not have min/MAX.

I'd like to get min/Max value for considering accuracy of sensing.
Could you provide it for me?

I'm looking forward to hearing back from you.


Best regards,
Kazuki Kuramochi

  • Kazuki-san,

    We are not able to post specification parameters outside of what appears in the datasheet.  However, the temperature compensation for the part has been set intentionally to help compensate for the behavior of a magnet at high temperatures.  Magnetic flux density will weaken at higher temperatures, and we intentionally set gain to increase to counter this effect.  All A type devices should exhibit this 0.12%/C, while the Z type devices should exhibit a relatively flat response.

    Thanks,

    Scott
