    Hall sensor IC for low current?

    Hello
    We wish to sense 200mA of current max in a LED drive circuit and there will be 200v of potential between the current sense bit and the output signal bit.
    No Hall sensors seem to do low current...eg these are all up to at least 20A

    Do you know of a low current one?

    Not sure if this is overkill, but: https://sensing.honeywell.com/index....ment/1/re_id/0
