Part Number: DRV5055

Hi team,

I'm not familiar with hall sensor. Could you help check below items?

Could DRV5055 replace MLX90290LUA? or do we need get some further information?

Regards,

Roy

  • Roy,

    These devices are pin to pin compatible, but have slight variations in the sensitivity options.  The sensitivity specification determines what magnetic field is required to produce a full scale output.  In both devices this will scale with the supply voltage.  While some sensitivity options will match, any replacement using a different value will require a change to system calibration.

    Many specifications for the two devices are quite comparable.  However, DRV5055 does have a 1 mA higher quiescent current, but also shows better linearity, Linearity error for MLX90290LUA is 1.5% where it is 1% on DRV5055.  

    Thanks,

    Scott
