USB5906-I/KD

Controllers Overview

The USB5906-I/KD 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 Battery Charging Revision 1.2 support for DCP, CDP, and SDP profiles, alongside an internal Hub Feature Controller enabling USB-to-I2C/SPI/GPIO bridging. 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 in a 100-pin VQFN package.

Controllers Feature Summary

• Native USB Type-C support with integrated multiplexing and PHY power management
• USB-IF Battery Charging 1.2 compliance with multiple charging profile emulation
• Internal Hub Feature Controller for custom I/O and register access via USB
• Programmable signal integrity features including PortSwap, PHYBoost, and VariSense

Controllers Applications

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

Controllers Procurement Notes

Verify the specific suffix '-I' indicates the industrial temperature grade range of -40°C to +85°C, distinct from the commercial variant. Confirm the 'KD' suffix corresponds to the 100-pin VQFN package type. Ensure the ordering code matches the exact datasheet designation to avoid functional differences related to temperature ratings or packaging.

Controllers Selection Notes

Select this component when a single upstream USB Type-C connection is required to expand into six downstream legacy USB ports. It is suitable for designs needing embedded control via the Hub Feature Controller or specific battery charging emulation without external logic. Consider the 100-pin VQFN footprint and thermal requirements for the target application environment.

Controllers Part Context

This part belongs to Microchip's USB59xx Smart Hub family, designed for high-performance USB connectivity. It complements other variants like the USB5903 or USB5916 by offering a specific balance of port count and Type-C integration. The series emphasizes low power consumption and flexible OEM configuration through hardware straps or non-volatile memory.

Controllers Replacement Considerations

Publicly confirmed parameter-equivalent substitutes include the USB5906CT/KD and USB5916CT/KD. Verify that any replacement maintains the same 100-pin VQFN package and temperature rating if the industrial grade is required.
