Description for the TUSB321

The TUSB321 device enables USB Type-C ports with the configuration channel (CC) logicneeded for Type-C ecosystems. The TUSB321 device uses the CC pins to determine port attach anddetach, cable orientation, role detection, and port control for Type-C current mode. The TUSB321device can be configured as a downstream facing port (DFP), upstream facing port (UFP) or a dualrole port (DRP) making it ideal for any application.

The TUSB321 device when configured as a DRP alternates configuration as a DFP or UFPaccording to the Type-C Specifications. The CC logic block monitors the CC1 and CC2 pins for pullupor pulldown resistances to determine when a USB port has been attached, the orientation of thecable, and the role detected. The CC logic detects the Type-C current mode as default, medium, orhigh depending on the role detected. VBUS detection is implemented todetermine a successful attach in UFP and DRP modes.

The device operates over a wide supply range and has low-power consumption.
