TUSB320LAIRWBR

The TUSB320 device uses the CC pins to determine the port connection status and cable orientation, as well as perform role detection and Type-C current mode control. The TUSB320 device can be configured as a downstream port (DFP), an upstream port (UFP), or a dual-role port (DRP), making it an ideal choice for various applications. According to the Type-C specification, the TUSB320 device alternates between being configured as a DFP or a UFP. The CC logic block monitors the pull-up or pull-down resistors on the CC1 and CC2 pins to determine when a USB port is connected, the orientation of the cable, and the detected role. The CC logic determines whether the Type-C current mode is default, medium, or high based on the detected role. This logic determines whether the port is successfully connected in UFP and DRP modes by implementing VBUS detection. Devices in this series can operate over a wide power supply range and have low power consumption. The TUSB320 is available in two enable versions: active-low enable, called TUSB320LA; and active-high enable, called TUSB320HA. Devices in the TUSB320 series are suitable for the industrial temperature range.
