TPS40303: TPS40303+UCC27200, How to achieve OCP and SCP function?

Part Number: TPS40303
Other Parts Discussed in Thread: UCC27200


    I used TPS40303+ UCC27200, now I have some question.

    Because TPS43030 pin 9 through UCC27200 to MOS.

    How to achieve OCP and SCP function?

    I think PIN9 can't detection current change on MOS, so TPS40303 PIN9  could be no function.
