The PI5USB30213A is a dual differential channel bi-directional multiplexer/de-multiplexer switch solution for USB 3.0 Type-C™ connector applications. PI5USB30213A switches between the USB controller and the new Type-C connector. It supports host mode, device mode and dual-role model 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.
PI5USB30213A 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, the system can monitor ID pin to know the connector status while default current mode is set. Systems running in device mode can monitor system VBUS for connector status as well as OUT1 and OUT2 pins for host's charging profile capability.
Enabling I2C control mode allows high flexibility for port control and communications through register read/write in PI5USB30213A. There is also flexibility to support default, 1.5A, and 3A current models. An interrupt signal for indicating changes with the I2C register 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.
