TPS65982: Migrate to TI new USB-C PD chips

Tool/software:

Hi Team,

We have a USB-C hub that uses the TPS65982 to charge an upstream notebook PC and provide 4 downstream ports. In this design, the TPS65982 acts as a source and provides 5 V / 12 V / 15 V / 20 V by switching the feedback resistors of a buck converter through its GPIO pins. It also controls the USB SuperSpeed MUX via a GPIO. These GPIO functions can be configured using the customization tool.

Could you recommend TI devices such as the TPS26750 for a similar application? From what I have seen, the web-based customization tool does not provide options to configure GPIO pins, and I am also unable to download a Windows offline version.

Hi,

Will this hub require USBPD compliance? how many type-C ports are on there and what DCDC is used here?

Hi Tommy,

No, it does not need to be USB PD compliant. We only use it for the upstream USB-C port, the oother 4 DFP ports are USB-A. We are using standard buck converters such as the Analog Devices LTC3854.

Best Regards,

Steve

What is the UFP port capability you are looking for in terms of power and data? Are you looking for DisplayPort or other alternate modes?
