DRV5053: Alternative part to the DRV5053

Wouter Kragt
Intellectual 1330 points
Part Number: DRV5053
Other Parts Discussed in Thread: DRV5032, TMAG5231, DRV5056, DRV5055

Hi SENSING team,

Do we have a part with a higher magnetic field sensitivity than the DRV5053 with an analog output?

Further, do we have an alternative for AH1912-FA-7, that has a very small height, < 0.37mm?

Thank you.

Kind regards,

Wouter Kragt

    Hello Wouter,

    Thanks for posting to the sensors forum!

    For the AH1912-FA-7, this is an omnipolar magnetic switch a good alternative device would be the TMAG5231 or the DRV5032 both of these device come in an X2SON package with a max height from the seating plane of 0.4mm while the competitor device height is typical 0.5mm. 

    For the DRV5053 replacement with higher sensitivity the highest sensitivity device would be the DRV5056 which offers up to 200mV/mT but unlike the DRV5053 this is a unipolar device and not bipolar as well as ratiometric which means the output scales with the input Vcc of the device. Another option would be the  DRV5055 with a sensitivity of 100mV/mT and is also bipolar device and ratiometric.

    I hope this helps let me know if there are any questions!

    Best,

    Isaac

    Hello Isaac,

    Thank you for the elaborate answer!

    For the DRV5053, at the moment they have a small output swing due to the small variety in the sensed input, which is why they want a more part with a higher sensitivity.

    Is there another way how we can get the output swing larger, without adding an amplifier orso?

    Kind regards,

    Wouter

    Hello Wouter,

    No worries always glad to help out! 

    If the voltage swing is small, this might indicate that they might not be using the most optimal magnet strength for their mechanical movement.

    Have they tried simulating their device to magnet behavior for their system using our TIMSS simulation tool?

    TIMSS allows users to simulate some our devices along with mechanical movement of a magnet, this gives users the ability to simulate the expected magnetic field as well as emulate the expected device output behavior. If they are not getting as large of a voltage swing as they would like my recommendation would be to try different magnets or device sensitivities to try to optimize the design. 

    Please let me know if any help is needed with these simulations.

    Best,

    Isaac
