USB5906/KD

Controllers Overview

The USB5906 is a low-power, OEM-configurable USB 3.1 Gen 1 hub controller featuring six downstream ports and a single upstream USB Type-C port. It supports Super-Speed (5 Gbps), Hi-Speed (480 Mbps), Full-Speed (12 Mbps), and Low-Speed (1.5 Mbps) data rates. The device integrates an internal Hub Feature Controller for I2C/SPI/GPIO bridging and supports USB-IF Battery Charging revision 1.2 profiles including DCP, CDP, and SDP. Configuration options include OTP ROM, SPI ROM, or configuration straps. It operates within commercial (0°C to +70°C) and industrial (-40°C to +85°C) temperature ranges.

Controllers Feature Summary

• Native USB Type-C support with integrated multiplexer and PHY power management
• Internal Hub Feature Controller enabling USB-to-I2C/SPI/GPIO bridge functionality
• Programmable signal integrity features including PortSwap, PHYBoost, and VariSense
• Support for USB Power Delivery Billboard Device enumeration on negotiation failure

Controllers Applications

• Standalone USB Hubs
• Laptop Docks
• PC Motherboards
• Multi-function USB 3.1 Gen 1 Peripherals

Controllers Procurement Notes

Verify the specific suffix against the manufacturer's current datasheet to confirm package type and temperature grade. Ensure the ordering code matches the required configuration method, such as OTP or SPI ROM support. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process before finalizing procurement.

Controllers Selection Notes

Select this component when a compact solution with native USB Type-C upstream connectivity is required. Consider the integrated battery charging detection if powering mobile devices. Evaluate the need for the internal Hub Feature Controller for system monitoring versus external GPIO availability. Verify that the 100-pin VQFN package fits the PCB layout constraints.

Controllers Part Context

The USB5906 belongs to Microchip's SmartHub family of USB controllers. It is designed to replace legacy hub solutions by integrating USB 3.1 Gen 1 capabilities with advanced power management and configuration flexibility in a single chip, reducing bill of materials count for modern computing platforms.
