Description for the TUSB320
The TUSB320 device enables USB Type-C ports with the configurationchannel (CC) logic needed for Type-C ecosystems. The TUSB320 device uses theCC pins to determine port attach and detach, cable orientation, role detection, and port controlfor Type-C current mode. The TUSB320 device can be configured as a downstreamfacing port (DFP), upstream facing port (UFP) or a dual role port (DRP) making it ideal for anyapplication.
The TUSB320 device 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. TheTUSB320 device is available in industrial and commercial temperatureranges.
