Simplified Schematic
3 Description
The TUSB320 device enables USB Type-C ports with the configuration channel (CC) logic needed for Type C ecosystems. The TUSB320 device uses the CC pins to determine port attach and detach, cable orientation, role detection, and port control for Type-C current mode. The TUSB320 device 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 TUSB320 device alternates configuration as a DFP or UFP according to the Type-C Specifications. The CC logic block monitors the CC1 and CC2 pins for pullup or pulldown resistances to determine when a USB port has been attached, the orientation of the cable, and the role detected. The CC logic detects the Type-C current mode as default, medium, or high depending on the role detected. VBUS detection is implemented to determine a successful attach in UFP and DRP modes.
The device operates over a wide supply range and has low-power consumption. The TUSB320 device is available in industrial and mercial temperature ranges.
