USB5806-I/KD

Controllers Overview

The USB5806-I/KD is a low-power, OEM-configurable USB hub controller featuring six downstream ports compliant with USB 3.2 Gen 1 and USB 2.0 standards. It supports data rates of 5 Gbps (SuperSpeed), 480 Mbps (Hi-Speed), 12 Mbps (Full-Speed), and 1.5 Mbps (Low-Speed). 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. It operates within a temperature range of -40°C to +85°C and utilizes a 100-pin VQFN package.

Controllers Feature Summary

• Supports FlexConnect functionality allowing dynamic role swapping between upstream and downstream ports.
• Includes PortSwap capability for programmable differential pair signal alignment on the PCB.
• Integrates PHYBoost and VariSense features for adjustable drive strength and receive sensitivity.
• Enables Port Split operation for independent enumeration of USB 3.2 Gen 1 and USB 2.0 devices.

Controllers Applications

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

Controllers Procurement Notes

Verify the specific suffix against the manufacturer's official documentation to confirm the exact operating temperature range and packaging configuration. Ensure that any ordering suffixes are interpreted strictly according to the provided datasheet definitions to avoid functional mismatches in industrial or commercial environments.

Controllers Selection Notes

Select this component when a six-port USB 3.2 Gen 1 solution with integrated battery charging detection is required. Consider the industrial temperature rating (-40°C to +85°C) for robust environmental operation. Evaluate the need for external SPI ROM or OTP programming if custom OEM configurations beyond default straps are necessary for the target application.

Controllers Part Context

This part belongs to the Microchip USB5806 SmartHub family, designed for embedded USB applications requiring high port density and advanced power management. The series includes variants with different temperature ratings and packaging options, all sharing the core six-port SuperSpeed architecture and Hub Feature Controller capabilities.

Controllers Replacement Considerations

Public confirmed substitute part numbers are not available in the verified source material. Consult Microchip Technology directly for current cross-reference information or alternative product recommendations.

Controllers FAQ

What battery charging standards does the USB5806 support?

The device supports USB-IF Battery Charging Revision 1.2, including Dedicated Charging Port (DCP), Charging Downstream Port (CDP), and Standard Downstream Port (SDP) profiles.

How does the FlexConnect feature function?

FlexConnect allows one downstream port to be reconfigured as the upstream port via a control input, enabling master-capable devices to control other devices on the hub.

What is the purpose of the PortSplit feature?

PortSplit allows the USB 3.2 Gen 1 and USB 2.0 portions of specific downstream ports to operate independently, enumerating two separate devices in parallel for custom applications.
