USB5806T/KD

Controllers Overview

The USB5806T/KD is a Microchip Technology USB Hub Feature Controller IC featuring six USB 3.2 Gen 1 / USB 2.0 downstream ports. It supports Super Speed (SS) at 5 Gbps, Hi-Speed (HS) at 480 Mbps, Full-Speed (FS) at 12 Mbps, and Low-Speed (LS) at 1.5 Mbps. The device operates on supply voltages of 1.08 V to 1.32 V and 3.0 V to 3.6 V. It includes integrated battery charging support compliant with USB-IF Battery Charging Revision 1.2, offering DCP, CDP, and SDP profiles. The component is housed in a 100-pin VQFN package measuring 12 mm x 12 mm.

Controllers Feature Summary

• Supports FlexConnect functionality allowing dynamic swapping between upstream and downstream port roles for master-capable devices.
• Includes an internal Hub Feature Controller enabling USB-to-I2C/SPI/GPIO bridge endpoint support and direct register access.
• Provides PHYBoost and VariSense capabilities for programmable drive strength and receive sensitivity to maintain signal integrity.
• Features PortSplit capability allowing 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 exact ordering suffix against the manufacturer's current documentation to confirm package type and temperature grade. Confirm availability status as distribution channels may list obsolete or end-of-life inventory. Ensure compatibility with required configuration methods such as OTP or SPI ROM before finalizing procurement.

Controllers Selection Notes

Select this controller for designs requiring six downstream ports with simultaneous USB 3.2 Gen 1 and USB 2.0 connectivity. Consider the integrated battery charging detection if supporting portable device charging is required. Evaluate the need for FlexConnect or PortSplit features based on system topology requirements. Verify that the host system supports the necessary USB standards for optimal performance.

Controllers Part Context

This component belongs to the USB5806 family of SmartHub controllers from Microchip Technology. It is designed as a low-power, OEM-configurable hub solution. The 'T' suffix typically indicates tape and reel packaging, while 'KD' denotes the commercial temperature range and VQFN package variant within the product identification system.

Controllers Replacement Considerations

Publicly confirmed parameter-equivalent substitutes include the USB5906CT/KD and USB5916CT/KD. These alternatives offer similar hub controller functionalities but may differ in specific pinouts or feature sets. Verify electrical characteristics and firmware compatibility when transitioning to these parts.
