    Hi Polly, 

    Thanks for reaching out to the High Power Drivers tea, my name name is Mamadou Diallo, I will help address your questions.

    Please find attached our current solution using UCC27282 or TPS28225.

    Please note that this solution requires a floating bias using SN6501 and a small transformer to provide bias to the high-side N-channel FET.

    UCC27282 through its UVLO allows operation for VDD>5V and this solution can handle bus voltages up to 100V when using UCC27282. 

    You can implement the current externally using a general purpose amplifier for cost purposes.

    Please let us know if you have further questions or press the green button if this addressed your question.

    Regards,

    -Mamadou
