DRV5053: How many tesla can this sensor measure? DVR5053 hall effect sensor.

Part Number: DRV5053

      I'm having a problem with the measurement with this sensor, the sensor data sheet does not give me information that hits with the sensors I have, the data sheet DVR5053 of the hall sensor does not talk about specs coming in the sensor, for example my sensors printed in them acronyms as 4C2CF alca and in the other 580YF alca. and my biggest doubt is, how many tesla can I measure with these sensors and how sensitive are they to the making of the cover? because in the data sheet it has values like - 11mv / mT (OA), - 23 mV / mT (PA). these acronyms OA and PA can not find fault in the sensor. I hope you can help me. Thank you.

  • Hi Raphael,

    Thanks for using our forums. I forwarded your question to our Hall Effect apps engineer. He will get back to you shortly.
  • Hi Raphael,

    Devices with ALCA marking correspond to the following devices:

    DRV5053CAQDBZR

    DRV5053CAQDBZT

    DRV5053CAQLPG

    DRV5053CAQLPGM

    They are all CA code, corresponding to +23 mV/mT.

  • thank you very much, this answer help me. but a have same doubt, in sensor`s datasheet is write this sensor is unlimited, but this devace have value max and i need to know the value right this devace measure in Gaus or Tesla, because a have one magnet of 3500 gaus and this sensor arrived in value max, so i can`t compere and a don`t know if my device is calibrate. sorry for the inconvenience but I have little knowledge in electronics.
  • Hello Raphael,

    What you are referring to is the "Absolute Maximum Rating" on BMAX. This specification just means that applying very strong magnetic fields will not damage the device (see footnotes (1) and (2) in section 6.1). This does not represent the maximum value of flux density that the DRV5053 can measure. That is given by the "saturation field" specification (BSAT).

    I would highly recommend reviewing our Hall Sensor forum FAQs to increase your knowledge of Hall sensors. Here is the link:

    In particular, the following document may be helpful in explaining some of the datasheet specifications.

    Best Regards,
