TPS25750: Is this part can only be used for 'power-only'?

Part Number: TPS25750
Other Parts Discussed in Thread: TUSB8041, BQ25792, , TPS25751

Hi,

I'm working on a design with combination of TPS25750D, BQ25792 and TUSB8041. And encountered some problems. And I find the TPS25750 is advised as:

"TPS25750 is optimized for power-only USB Type-C PD applications"

Does it means the chip is not suitable to be used with USB data communications? We use the three chip as below:

The TUSB chip and TPS chip share the USB2.0 wires (D+/D-), will it work?

Thanks.

    Hi Diverger, 

    TPS25750 supports recognizing up to USB3.2 Gen2x2, this is configurable through the online Application Customization Tool. If your system requires support for BC1.2, the D+/D- pins will need to be connected to GPIO 4 and 5 of TPS25750. 

    For new designs that requires PD3.1 specification, I recommend switching to TPS25751 instead. TPS25751 is the next generation device of TPS25750, P2P and register compatible, is compliant with PD3.1 specs and comes with additional feature such as PPS charging and Liquid Detection. 

    Thanks and Regards,

    Hi,Lin

    So, it can be used together with data communications, and the D+/D- can be routed directly to the D+/D- pins of the MCU, right?

    Hi Diverger, 

    Yes that is correct, if you do not need BC1.2 support then the D+/D- lines do not need to be routed to TPS25750. From the online GUI you can configure specific GPIOs of TPS25750 to specific events such as cable connect, cable flip, enter USB mode in order to control the TUSB mux. 

    Thanks and Regards,
