TPS65987D: PD controller supporting PD3.1(EPR support)

Part Number: TPS65987D
Other Parts Discussed in Thread: TPS65987

Hi TI Team:

Is there a PD controller that supports PD3.1? My design requirement is a 140W(28V/5A) DRP. I can't find a chip that can support PD3.1 on the official website.

    Hello Peiwu,

    Unfortunately we do not have a device available at this time, but our team is working on releasing a PD3.1 EPR controller sometime during 2H23. 

    Would you also be able to elaborate on the end equipment you are wanting to implement this new technology on?

    Thanks Adam：

    The usage scenario is the same as TPS65983/tps65987. The microcontroller W/R the registers of the PD controller through I2C to configure it as DFP, DRP, and UFP. 

    Our device can be used as a power provider or a power consumer (EPR 140W), 

    1. Charge the Macbook with 140W.

    2. Negotiate with the Apple adapter to make it output 140W.

    ...

    And also need support Alternate Mode.

    Hi Peiwu, 

    Thank you for the additional information. Unfortunately at this time, we do not have plans of releasing a device that supports both the new PD3.1 spec as well alternate mode negotiation. However, this may change as the year progresses. I would reach out 2Q23 to see the latest on our PD3.1 plans and the devices we plan to release.
