Hello,

I went through reference design TIDU820. I found TQPL50A  datasheet is not available online. Please suggest hall element and ferromagnetic core part number

Best Regards,

    Hello Raju,

    As for the Hall-Element you can use the AKM HW-322 as stated in the datasheet.  As for the core you may need to design your own or find one with an airgap and windings to meet your requirements.  I normally use FEMM free software to evaluate the magnetic gain of a core.  The biggest effect will be the offset of the hall sensor but the gain impacts some of the performance.  You would like the gain of the core to be high.  

    Regards,
