USB5806CT-I/KD

Controllers Overview

The Microchip Technology USB5806CT-I/KD is a low-power, OEM-configurable USB 3.2 Gen 1 hub controller featuring six downstream ports. 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 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 a commercial temperature range of 0°C to +70°C and an industrial range of -40°C to +85°C, housed in a 100-pin VQFN package.

Controllers Feature Summary

• Supports USB 3.2 Gen 1 and USB 2.0 Link Power Management with integrated battery charging detection for multiple standards.
• Includes FlexConnect for upstream/downstream port role swapping and PortSwap for differential pair signal alignment.
• Features PHYBoost for programmable drive strength and VariSense for adjustable receive sensitivity to restore signal integrity.
• Enables Port Split for independent operation of USB 3.2 Gen 1 and USB 2.0 portions on specific ports.

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 the industrial temperature grade (-40°C to +85°C). Confirm the package type matches the 100-pin VQFN requirement. Ensure the ordering code aligns with the manufacturer's current production status and RoHS compliance documentation.

Controllers Selection Notes

Select this component for designs requiring six downstream ports with advanced signal integrity features like PHYBoost and VariSense. Consider the internal Hub Feature Controller if USB-to-I2C/SPI bridging is needed. Verify that the host system supports USB 3.2 Gen 1 speeds and that the power budget accommodates the integrated battery charging capabilities.

Controllers Part Context

The USB5806 series represents Microchip's SmartHub technology, combining high-speed data transfer with intelligent power management. The CT variant typically denotes a specific tape-and-reel packaging option, while the KD suffix specifies the industrial temperature range and VQFN package style.
