USB5906T/KD

Controllers Overview

The USB5906T/KD is a Microchip Technology USB hub controller featuring six downstream ports and one upstream USB Type-C port. It supports USB 3.1 Gen 1 (5 Gbps), USB 2.0 Hi-Speed (480 Mbps), Full-Speed (12 Mbps), and Low-Speed (1.5 Mbps) protocols. The device integrates an internal Hub Feature Controller for I2C/SPI/GPIO bridging, battery charging detection compliant with USB-IF BC1.2, and OEM configuration via OTP or SPI ROM. It operates within commercial (0°C to +70°C) and industrial (-40°C to +85°C) temperature ranges and is housed in a 100-pin VQFN package.

Controllers Feature Summary

• Native USB Type-C support with integrated multiplexer and PHY power management
• Internal Hub Feature Controller enabling USB-to-I2C/SPI/GPIO bridge functionality
• Smart port controller with programmable drive strength and receive sensitivity
• Support for USB Power Delivery Billboard Device enumeration

Controllers Applications

• Standalone USB Hubs
• Laptop Docks
• PC Motherboards
• Multi-function USB 3.1 Gen 1 Peripherals

Controllers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific ordering suffix matches the required package and temperature grade. Check for current product discontinuance notifications as availability may be limited. Ensure all regulatory compliance documentation, including RoHS status, is obtained prior to integration into final designs.

Controllers Selection Notes

Select this component for designs requiring native USB Type-C upstream connectivity alongside legacy downstream ports. Consider the internal Hub Feature Controller if system monitoring via I2C or SPI is needed. Verify that the 100-pin VQFN footprint fits the PCB layout constraints. Ensure the host system supports the required USB standards and battery charging profiles for full feature utilization.

Controllers Part Context

The USB5906 series includes variants such as the USB5906CT/KD and USB5916T/KD. These models share similar core functionalities but may differ in packaging options or specific downstream port configurations. The USB5906T/KD specifically denotes the tape and reel packaging variant of the standard 100-pin VQFN hub controller.

Controllers Replacement Considerations

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