Controllers FAQ

How does the USB7206 handle battery charging?

It supports USB-IF Battery Charging revision 1.2, enabling Dedicated Charging Port (DCP), Charging Downstream Port (CDP), and Standard Downstream Port (SDP) profiles on downstream ports.

What is the function of the FlexConnect feature?

FlexConnect allows the roles of the upstream and all downstream ports to be reversed on command, enabling master-capable devices to control other devices on the hub.

Can the USB 3.2 Gen 2 and USB 2.0 portions of certain ports operate independently?

Yes, the PortSplit feature allows the USB 3.2 Gen 2 and USB 2.0 portions of downstream ports 3, 4, and 5 to operate independently and enumerate separate devices in parallel.
