DRV421: Fluxgate Magnetic Current Sensing- Compensation Coil Selection, Sumida transformer SC3113-50 or alternates

Part Number: DRV421
We are investigating ways we can utilize the DRV421 fluxgate chip in our application. From our web searches we found TI Design note: Fluxgate Magnetic Current Sensing with High Linearity for Three Phase inverters Reference Design, call out a Sumida transformer SC3113-50, which could be very relevant and useful for our application. We were unable to find more information on the transformer, and were wondering if you had any details regarding them, or possible similar alternatives we could explore.
  • Hi Shafi,

    Thank you for considering the DRV421 for your application. The SC3113-50 was custom-fabricated for the reference design you're alluding to, and unfortunately there are no off-the-shelf alternatives currently available. We can certainly help you with designing a core, or suggest possible workarounds if you could share additional details about your application and design goals.

    Best Regards,
