USB5926CT-I/KD

Controllers Overview

The Microchip Technology USB5926C/I/KD is a 6-port USB 3.1 Gen 1 Smart Hub controller featuring two downstream Type-C ports, two legacy SuperSpeed ports, and two legacy USB 2.0 ports. It supports 5 Gbps, 480 Mbps, 12 Mbps, and 1.5 Mbps data rates with native USB Type-C support and integrated multiplexers. The device includes an internal hub feature controller for I2C/SPI/GPIO bridging, USB Link Power Management (LPM), and Battery Charging Revision 1.2 compliance. Configuration is managed via OTP or SPI ROM, and it operates within the industrial temperature range of -40°C to +85°C in a 100-pin VQFN package.

Controllers Feature Summary

• Native USB Type-C support with integrated multiplexers and PHY power management
• Internal hub feature controller enabling USB-to-I2C/SPI/GPIO bridge functionality
• Smart port controller operation with firmware-managed companion port power
• Support for USB-IF Battery Charging Rev 1.2 profiles including DCP, CDP, and SDP

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' indicates the industrial temperature grade (-40°C to +85°C) as distinct from commercial variants. Confirm package marking and RoHS compliance status against the latest datasheet revision DS00003190A. Ensure ordering documentation matches the exact part number format to avoid substitution errors during procurement.

Controllers Selection Notes

Select this component when designing systems requiring multiple USB Type-C downstream connections alongside legacy ports. The industrial temperature rating makes it suitable for harsh environments. Consider the onboard microcontroller capabilities if custom OEM configurations via OTP or SPI are required instead of external host configuration.

Controllers Part Context

This device belongs to the USB5926 family of 6-port USB 3.1 Gen 1 Smart Hubs. It shares architectural similarities with the USB5906 and USB5916 but offers enhanced Type-C integration and flexible port splitting capabilities. The 'I' suffix specifically denotes the extended operating temperature range compared to standard commercial versions.
