Part Number: TPS65994AE


What's the reason cause TPS65994AE assert PROCHOT# on GPIO9?

Is there any document to explain the behavior?

Thanks a lot.

    Gary,

    The PROCHOT# GPIO event is a very fast indicator that one of the following events has occured:

    This recommended to be assigned to a specific GPIO
    (check data-sheet). This is asserted low when certain power
    events occur.
    • When a source or sink is connected.
    • When the source is disconnected.
    • Upon entry into a new Explicit Contract as a sink that
    reduces voltage or current.
    • When a PR_swap is accepted.
