USB5806T-I/KD

Controllers Overview

The USB5806T-I/KD is a Microchip Technology USB Hub Feature Controller IC supporting six USB 3.2 Gen 1 downstream ports and one upstream port. It operates at data rates of 5 Gbps, 480 Mbps, 12 Mbps, and 1.5 Mbps. The device supports USB-IF Battery Charging revision 1.2 (DCP, CDP, SDP) on all ports. It features FlexConnect for upstream/downstream port swapping, PortSwap for differential pair alignment, PHYBoost for signal integrity restoration, and VariSense for programmable receive sensitivity. Configuration is supported via OTP ROM, SPI ROM, or SMBus. The component is housed in a 100-pin VQFN package measuring 12mm x 12mm.

Controllers Feature Summary

• Supports USB 3.2 Gen 1 SuperSpeed operation alongside legacy USB 2.0 speeds with integrated termination resistors.
• Includes an internal Hub Feature Controller enabling USB to I2C/SPI/GPIO bridge functionality.
• Provides OEM configuration flexibility through Configuration Straps, OTP ROM, or external SPI ROM.
• Integrates battery charging detection circuits compliant with USB-IF BC1.2 standards.

Controllers Applications

• Standalone USB Hubs
• Laptop Docks
• PC Motherboards
• Multi-function USB 3.2 Gen 1 Peripherals

Controllers Procurement Notes

Verify the specific suffix 'I' indicates industrial temperature range support (-40°C to +85°C). Confirm the 'T' designation corresponds to the tape and reel packaging format. Ensure compatibility with the required host operating systems including Windows 10, 8, 7, XP, Apple OS X, and Linux drivers before finalizing procurement specifications.

Controllers Selection Notes

Select this model when six downstream ports are required with independent power control capabilities. Consider the industrial temperature grade if the application environment exceeds commercial limits. Evaluate the need for FlexConnect or PortSwap features if system topology requires reversible upstream connections or simplified PCB trace routing.

Controllers Part Context

This component belongs to the USB5806 series of SmartHub controllers from Microchip Technology. It is designed as a low-power, OEM-configurable hub controller that decouples SuperSpeed transfers from USB 2.0 bottlenecks. The series includes variants with different temperature ratings and packaging options to suit various embedded USB application requirements.

Controllers Replacement Considerations

Publicly confirmed parameter-equivalent substitutes include the USB5906CT/KD and USB5916CT/KD. Verify pinout compatibility and feature parity before substitution. Consult official documentation for any functional differences between the USB5806 and USB59xx series devices.

Controllers FAQ

What is the function of the FlexConnect feature?

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

How does the USB5806 handle battery charging?

It supports USB-IF Battery Charging revision 1.2, detecting and enabling Dedicated Charging Port (DCP), Charging Downstream Port (CDP), and Standard Downstream Port (SDP) profiles.

What is the purpose of the VariSense feature?

VariSense controls USB receiver sensitivity, allowing programmable levels to enable operation in sub-optimal system environments such as those using captive USB cables.
