FTDI Chip High-Speed USB Bridge ICs with Type-C/PD 3.0 Controllers fully support the latest USB Type-C and Power Delivery (PD) standards. This enables the support for power negotiation with the ability to sink or source current to USB host devices. These high-speed USB bridge devices feature up to two PD ports viz, PD1 port and PD2 port. The PD1 port shares the same Type-C connector with USB data and the PD2 port is the power port only without USB data. The high-speed USB bridge ICs support 5V, 9V, 12V, 15V, and 20V PDO profiles and these profiles are configurable through an external EEPROM at power-up/reset.

The high-speed USB bridges offer up to 40Mbytes/s data rates and multi-channel interfacing. The benefit of a multi-channel bridge is that the system BOM is reduced by removing the need for a USB hub chip. Additionally, each channel of the device appears to the host PC as a separate device. This enables each channel to be independently configured for different modes such as UART, MPSSE, or FIFO. Also, with different parameters such as 4 UARTS all operating with different baud rates.

Features
