Semiconductors\Interface ICs\USB Interface ICHD3SS3220 USB Type-C DRP Port ControllerTexas Instruments HD3SS3220 USB Type-C DRP Port Controller is a USB SuperSpeed (SS) 2: 1 mux with a DRP port controller. The device provides Channel Configuration (CC) logic and 5V VCONN sourcing for ecosystems implementing USB Type-C. The HD3SS3220 can be configured as a Downstream Facing Port (DFP), Upstream Facing Port (UFP), or a Dual Role Port (DRP) making it ideal for any application. The HD3SS3220, in DRP mode, alternates presenting itself as a DFP or UFP according to the Type-C specifications. The CC logic block monitors the CC1 and CC2 pins for pull-up or pull-down resistances to determine when a USB port has been attached and its port role. Once a USB port has been attached, the CC logic also determines the orientation of the cable and configures the USB SS mux accordingly. Finally, CC logic advertises or detects Type-C current mode - Default, Mid, or High in DFP and UFP modes respectively.
