【文字介紹】The TUSB320 device enables USB Type-C ports with the configuration channel (CC) logic needed for TypeC 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 commercial temperature ranges.
