Texas Instruments  TUSB320HAIRWBR

The TUSB320LA and TUSB320HA devices, hereaftercalled TUSB320 unless otherwise noted, are Texas Instrument’s third generationType-C configuration channel logic and port controller. The TUSB320 devicesuse the CC pins to determine port attach and detach, cable orientation, role detection, and portcontrol for Type-C current mode. The TUSB320 devices can be configured as adownstream facing port (DFP), upstream facing port (UFP) or a dual role port (DRP) making themideal for any application.

The TUSB320 devices have an alternate 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 devices operate over a wide supply range and have low-power consumption. TheTUSB320 is available in two versions of enable: Active low enable calledTUSB320LA and active high enable called TUSB320HA. TheTUSB320 family of devices are available in industrial temperature ranges.
