USB5806/KD

Controllers Overview

The USB5806 is a low-power, OEM-configurable USB 3.2 Gen 1 hub controller featuring six downstream ports and advanced embedded features. It supports Super-Speed (5 Gbps), Hi-Speed (480 Mbps), Full-Speed (12 Mbps), and Low-Speed (1.5 Mbps) operations. The device integrates a Hub Feature Controller for I2C/SPI/GPIO bridging, FlexConnect for upstream/downstream port swapping, and PortSwap for differential pair alignment. It includes PHYBoost for signal integrity restoration and VariSense for programmable receive sensitivity. Configuration is supported via configuration straps, OTP ROM, or SPI ROM.

Controllers Feature Summary

• Supports USB-IF Battery Charging revision 1.2 with DCP, CDP, and SDP profiles on all ports
• Includes an internal Hub Feature Controller enabling USB to I2C/SPI/GPIO bridge functionality
• Provides FlexConnect capability allowing downstream port reconfiguration as the upstream port
• Integrates PHYBoost and VariSense technologies for enhanced signal drive strength and receiver sensitivity

Controllers Applications

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

Controllers Procurement Notes

Verify the specific suffix of the ordered part number against the datasheet Product Identification System to confirm temperature range and package type. Ensure that any ordering suffixes do not alter the functional specifications unless explicitly documented in official Microchip change notices. Confirm RoHS compliance status prior to procurement.

Controllers Selection Notes

Select the USB5806 when a 6-port USB 3.2 Gen 1 solution with integrated battery charging detection is required. Consider this component for designs needing flexible port topology via FlexConnect or custom OEM configurations through OTP or SPI interfaces. Evaluate thermal dissipation requirements given the VQFN package and operational power characteristics.

Controllers Part Context

The USB5806 belongs to Microchip's SmartHub family of USB interface controllers. It is designed for high-performance embedded applications requiring robust USB connectivity and advanced power management features. The device complements other Microchip USB solutions by providing a fully compliant hub controller with integrated feature capabilities.

Controllers Replacement Considerations

Publicly confirmed parameter-equivalent substitutes include the USB5906C/KD, USB5916C/KD, and USB5926C/KD from Microchip Technology. Verify pin compatibility and firmware requirements before substitution.

Controllers FAQ

What is the function of the FlexConnect feature?

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

How does the Hub Feature Controller benefit system design?

It provides an internal USB device endpoint that acts as a bridge to I2C, SPI, or GPIO interfaces, allowing external circuits to be monitored or controlled via the USB connection.

What battery charging standards are supported?

The USB5806 supports USB-IF Battery Charging Revision 1.2, including Dedicated Charging Port (DCP), Charging Downstream Port (CDP), and Standard Downstream Port (SDP) profiles.
