• Includes integrated 2:1 MUXes for direct support of USB Type-C ports
• Supports PortSplitting to separate USB 2.0 and USB 3.1 Gen1 interfaces
• Features embedded Billboard class device for power delivery notification

Controllers Applications

• Standalone USB hubs
• Laptop docks
• PC motherboards
• Multi-function USB 3.1 Gen1 peripherals

Controllers Procurement Notes

Verify the specific suffix 'T' against the official datasheet to confirm tape-and-reel packaging requirements. Confirm current lifecycle status as distributors may list this part as discontinued or end-of-life. Ensure compatibility with existing system voltage rails before procurement.

Controllers Selection Notes

Select this model when a design requires multiple USB Type-C connections combined with standard Type-A ports. Verify that the host system supports the required USB 3.1 Gen1 protocol. Consider the 100-pin VQFN footprint constraints during PCB layout planning.

Controllers Part Context

This component belongs to the USB58XX/59XX family of SuperSpeed USB 3.1 Gen1 SmartHub controllers designed for USB Type-C applications. It shares core architecture with variants like the USB5916 and USB5906, differing primarily in the number and type of integrated USB Type-C ports available on the chip.

Controllers Replacement Considerations

Public confirmed substitutes include USB5916T/KD and USB5906T/KD. These parts share the same package and core functionality but offer different configurations of upstream and downstream USB Type-C ports.
