Type-C Dual Role Port Controller with USB 3.2 Gen 2 10Gbps Mux

The PI5USB31213A is a 10Gbps dual differential channel bi-directional multiplexer/de-multiplexer switch solution for USB 3.2 Gen 2 Type-C™ connector applications. PI5USB31213A switches between the USB controller and the new Type-C connector. It supports host mode, device mode and dual-role mode ports with automatic configuration based on the voltage levels detected on CC pin. It offers excellent signal integrity for high-speed signals at low power dissipation.

PI5USB31213A supports both pin and I2C control base on ADDR pin setting. In pin control mode, the PORT input pin determines the port setting, whether this is a host, device or dual-role port. In host mode, PI5USB31213A monitors ID pin to check connector status, it offers default current mode to power attached accessories. In device mode, PI5USB31213A monitors OUT1, OUT2, and OUT3 which report the detected host’s charging profile capability to allow the system to select the most appropriate charging schemes.

Enabling I2C control mode allows high flexibility for port control and communications through registers read/write in PI5USB31213A. There is also flexibility to support Default, 1.5A and 3A current modes. An interrupt signal for indicating changes with the I2C registers is sent to the master to notify the system any change in the Type-C connector while in parallel the system can still monitor ID pin.
