175VDC overcurrent detection and protection

Other Parts Discussed in Thread: DRV425, AMC1200

Dear Sirs

I have a need to monitor 175vdc current.  I need to be able to set the current threshold to open the 175vdc line upon reaching the threshold.  Does anyone know of an integrated solution?

    Hi Dennis,

    If you need a high side current sensing configuration, we don’t have a shunt based, non-isolated IC that that can take an input of 175VDC. You would have to look into isolation amplifiers such as AMC1200 and family, or magnetic current sensors such as DRV425.

    If you can use low side configuration then there would be more choices.

    Please check out TI current sensing support website, complete with e-book, app notes and videos, as well as product selection guide.

    Regards, Guang
