TPS25750: GPIO event change sourcePDO

Part Number: TPS25750

Hi team,

When used on the PD Sink side, what is the appropriate GPIO event to notify the SW side of the start of the current value change due to the Source PDO change? My customer expect that it will be launched by receiving an Accept from Source at any PDO and will be launched at PsRdy.

Regards,

Shoo

    The ideal approach would be to use INT_EVENT.NewContractAsCons, and then refer ACTIVE_CONTRACT_PDO register (0x34) and ACTIVE_CONTRACT_RDO register (0x35) for details on the negotiated PD contract. There's no direct GPIO event to notify the host of this change, but if you still need a GPIO to implement this functionality, please see if PdNegotiationInProcess (GPIO Event #76) meets your requirement.

    The details of these events/registers is @ TPS25750-TRM
