    Hi SHH,

    Fault is just an indicator pin.

    As OCP, will current limit no matter fault floating or not.

    Hi Zic,

    just to clarify here:

    do you mean, If customer float the fault pin,the IC will not be cutoff when OCP occurred ,it will still keep current limit value?


    thanks

    Regards,

    Hi Patty,

    I mean current limit function has no matter with fault floating or not.

    You can float fault or not float. Both operation will not influence current limit function.

    For TI's policy, I will first click resolved button.

    If you have any other concern, contact me any time.

    If you think resolved, please help click'Issue is solved button'.

    Thanks.
