TPS25750: How to determine which Power Delivery Bracket has been negotiated?

TPS25750: Enable system after Power Delivery Bracket has been negotiated

Part Number: TPS25750

I am currently designing a product in which we are considering using USB-C as both the power and data port.  The device will be a sink/target, only consuming power from the host with no internal battery.

The issue is that we cannot enable the system unless a power bracket of >=20W has been negotiated.  Does the TPS25750 have a way to disable the power path unless the correct power bracket has been negotiated?  An external enable flag off the GPIO would be fine for this as well.

    We are in the process of adding a feature that will enable a GPIO event when a contract of a specific voltage is negotiated.  This feature is under development now and will be released soon.

    We do not currently have an option that will do a power based event option.
