The TUSB320LI and TUSB320HI devices (remainder of this document called TUSB320 unless otherwise noted) enables USB Type-C ports with the configuration channel (CC) logic needed for Type-C ecosystems. The TUSB320 devices use the CC pins to determine port attach and detach, cable orientation, role detection, and port control for Type-C current mode. The TUSB320 devices 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 devices alternate 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 devices operate over a wide supply range and have low-power consumption. The TUSB320 is available in two versions of enable: Active low enable called TUSB320LI and active high enable called TUSB320HI. The TUSB320 family of devices are available in industrial temperature ranges.
