TUSB4020BI: USB hub IC that supports a single power supply

Part Number: TUSB4020BI

Dear TI Team

Our customer is looking for a USB hub product that supports speeds of 400Mbps or higher with 2 ports,
and suggested TUSB4020 to them, but it is said that it can not be used with a single power supply of 3.3V.

Among TI products, among the products that support 2 ports at High Speed (480 Mbps), the product that supports a single power supply could not be found on the Web.
Please let me know if you have any good devices.

Best Regards,
Y.Ottey

    Hi,

    TUSB4020BI is the correct device here as your customer is looking for a USB Hub. Unfortunately this is our only 2 USB 2 Hub solution and it does require 3.3V and 1.1 V power supply. Power regulator could be used to produce 1.1V supply form 3.3V supply assuming power capability is large enough.
