    Hey Roy,

    We do have some options for this, but the recommendation may change based on some of your system parameters. Do you already have a specific core you need to use, or are you designing a core around the sensor? If you have a specific core you need to use, what magnetic field range do you anticipate having at the sensor location?

    Regards,

    Mitch

    Hey Roy,

    Without the specifics of your system, you have two main options:

    • Linear Hall sensors, such as the DRV5055. This is most likely the option that you will want, since they come in a package similar to the one in your image that you can just wedge in the gap of the core. 
    • Magnetic current sensors, such as the TMCS110x devices. This option could work, but needs to be soldered onto a PCB, so there is usually a larger air gap, which may make it harder to design for. 

    The DRV5055 (and similar devices) are covered by a different team, so I am notifying them of this thread also, in case you need further support for those devices. 

    Regards,
    Mitch
