Texas Instruments  TUSB322IRWBR

The TUSB322I device enables USB Type-C ports with the configuration channel (CC) logicrequired for Type-C ecosystems. The TUSB322I device uses the CC pins to determine port attach anddetach, cable orientation, role detection, and port control for Type-C current mode. The TUSB322Idevice can be configured as a downstream facing port (DFP), upstream facing port (UFP), or a dualrole port (DRP), making the TUSB322I device ideal for any application.

The TUSB322I device alternates configuration as a DFP or UFP according to the Type-CSpecifications. The CC logic block monitors the CC1 and CC2 pins for pullup or pulldown resistancesto determine when a USB port has been attached, the orientation of the cable, and the roledetected. The CC logic detects the Type-C current mode as default, medium, or high depending on therole detected. VBUS detection is implemented to determine a successfulattach in UFP and DRP modes. The TUSB322I will supply VCONN when an active cable isdetected.

The device operates over a wide supply range and has low-power consumption. The TUSB322Idevice is available in industrial temperature ranges.
