USB5926-I/KD

Controllers Overview

The USB5926-I/KD is a monolithic 7-port USB 3.1 Gen 1 hub controller from Microchip Technology, designed for USB Type-C applications. It integrates SmartHub technology to support I/O bridging and FlexConnect port swapping. The device features one upstream-facing USB Type-C port and two downstream-facing USB Type-C ports, alongside five traditional USB Type-A downstream ports. It operates within an industrial temperature range of -40°C to +85°C and is housed in a 100-pin VQFN package measuring 12 x 12 mm.

Controllers Feature Summary

• SmartHub technology enables I/O bridging and FlexConnect port swapping to reduce bill of materials cost.
• Integrated 2:1 multiplexers provide direct interface support for USB Type-C ports.
• PortSplitting technology allows downstream ports to be split for parallel USB 2.0 and USB 3.1 connections.
• Built-in Billboard class device support facilitates power delivery notification offloading.

Controllers Applications

• Standalone USB hubs
• Laptop docks
• PC motherboards
• Multi-function USB 3.1 Gen 1 peripherals

Controllers Procurement Notes

Verify the specific suffix 'I/KD' against the official datasheet to confirm industrial temperature rating and tape-and-reel packaging status. Confirm current availability as distribution channels may list this component as obsolete or end-of-life. Ensure compatibility with required host drivers before procurement.

Controllers Selection Notes

Select this model when a design requires multiple USB Type-C connections combined with legacy Type-A ports. The integrated Hub Feature Controller simplifies designs by eliminating external bridging ICs. Verify that the 100-pin VQFN footprint fits the target PCB layout constraints.

Controllers Part Context

This component belongs to the USB58XX/59XX family of SuperSpeed USB 3.1 Gen 1 SmartHub controllers. These devices are engineered to simplify modern hub designs by integrating advanced switching and bridging capabilities into a single monolithic chip, reducing system complexity compared to tiered hub solutions.

Controllers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult Microchip technical support for alternative components if this specific SKU is discontinued or unavailable.
