TUSB322I に関する概要
The TUSB322I device enables USB Type-C ports with the configuration channel (CC) logic required for Type-C ecosystems. The TUSB322I device uses the CC pins to determine port attach and detach, cable orientation, role detection, and port control for Type-C current mode. The TUSB322I device can be configured as a downstream facing port (DFP), upstream facing port (UFP), or a dual role port (DRP), making the TUSB322I device ideal for any application.
The TUSB322I 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 TUSB322I will supply VCONN when an active cable is detected.
The device operates over a wide supply range and has low-power consumption. The TUSB322I device is available in industrial temperature ranges.
