What are the key features of USB5926CT/KD?
- 6-port USB 3.1 Gen 1 hub with 625 MBps max throughput for high-speed multi-device connectivity
- Multiple USB Type-C UFP and DFP role support enabling flexible upstream and downstream port configurations
- I2C, SMBus, SPI, and UART management interfaces for firmware-controlled port power and fault reporting
- 3.3 V supply option and 25 MHz clock supporting integration into compact embedded platform designs
What is USB5926CT/KD used for?
The USB5926CT/KD is designed for embedded computing modules, industrial gateways, and docking stations where 6 simultaneous high-speed USB 3.1 Gen 1 connections must be managed intelligently from a host processor. Its multi-interface management bus (I2C, SPI, UART) allows runtime control of per-port power delivery, over-current protection, and enumeration behavior, making it suitable for medical carts, digital signage players, and ruggedized field devices. Support for both USB Type-C UFP and DFP roles on the same hub enables reversible connector designs without external mux hardware.

Frequently Asked Questions
What is the maximum data throughput per port on USB5926CT/KD in a USB 3.1 Gen 1 configuration?
Each downstream port supports USB 3.1 Gen 1 at up to 5 Gbps line rate, translating to roughly 625 MBps effective throughput. This is sufficient for streaming uncompressed 4K video frames, transferring large industrial log files, or driving high-speed USB storage devices simultaneously across multiple ports.
How does USB Type-C UFP and DFP dual-role support on USB5926CT/KD simplify docking station designs?
By natively handling both Upstream Facing Port (UFP) and Downstream Facing Port (DFP) roles, the USB5926CT/KD eliminates the external USB Type-C mux ICs and role-detection logic typically required. This reduces BOM count by 3 to 5 components per port, saving PCB area in the compact 100-pin VQFN footprint.
Which management interfaces does USB5926CT/KD expose and what can a host processor control via them?
The hub exposes I2C, SMBus, SPI, and UART interfaces at 3.3 V logic levels, allowing the host to read per-port power draw, enable or disable individual ports, configure overcurrent thresholds, and retrieve link speed negotiation status. This level of runtime control is critical for medical device compliance and industrial asset management applications.
For a 6-port USB hub design requiring an 8-week lead time, how should procurement planning account for USB5926CT/KD availability?
With an 8-week factory lead time and a 2019 introduction date, the USB5926CT/KD has an established supply chain. For production volumes above 500 units, placing orders at least 10 weeks before board assembly and maintaining a minimum 2-week safety stock buffer is recommended to handle carrier transit variability and incoming inspection without line stoppages.
