Key Features

  • USB 3.1 Gen1 hub with 4 downstream ports supporting up to 5 Gbps per port data transfer rate
  • Native USB Power Delivery Type-C upstream port enabling 100 W charging and alt-mode negotiation
  • Mixed downstream port types: USB PD Type-C and USB Type-A for flexible device connectivity
  • Industrial temperature rating and I2C/SPI configuration interface for embedded and harsh-environment deployments

Applications

USB7051T-I/KDX is used in industrial USB docking stations, embedded computing modules, and ruggedized panel PCs that require a reliable multi-port USB 3.1 hub with Power Delivery support. Its native Type-C upstream with PD makes it suitable for laptop-class single-cable docks providing simultaneous 5 Gbps data and up to 100 W power delivery. The industrial temperature rating and QFN-100 package also make it appropriate for in-vehicle infotainment hubs, factory automation HMIs, and test equipment requiring long-term USB connectivity across -40°C to +85°C.

Frequently Asked Questions

What USB data transfer speed does USB7051T-I/KDX support per downstream port and in aggregate?

USB7051T-I/KDX supports USB 3.1 Gen1 at 5 Gbps per port, with an aggregate internal bus bandwidth of 625 MBps. This enables 4 downstream devices to transfer data simultaneously without significant throughput degradation, making it suitable for industrial test equipment, multi-drive storage enclosures, and embedded computing hubs requiring high-bandwidth multi-port USB expansion.

Does USB7051T-I/KDX support USB Power Delivery and which ports can negotiate charging power?

Yes, USB7051T-I/KDX includes a native USB Power Delivery Type-C upstream port capable of negotiating up to 100 W power contracts. The downstream ports include at least 1 PD-capable Type-C port, enabling pass-through charging and alt-mode video for connected devices. This combination suits single-cable docking station designs that deliver 5 Gbps data and high-wattage charging to laptops and tablets via a single USB-C cable.

Which configuration interfaces does USB7051T-I/KDX support for runtime setup in embedded systems?

USB7051T-I/KDX supports I2C and SPI serial interfaces for runtime configuration, allowing host processors to adjust hub parameters such as VID/PID strings, port power management, and downstream port enable/disable. This programmability is critical in embedded industrial panels and OEM computing modules where custom device identification strings and per-port power budgets must be set during factory programming or firmware initialization.

For an in-vehicle infotainment USB hub design, what temperature range does USB7051T-I/KDX cover?

USB7051T-I/KDX is rated for industrial temperature operation from -40°C to +85°C, covering automotive cabin environments, industrial HMI enclosures, and outdoor kiosk installations. The QFN-100 package with exposed thermal pad provides efficient heat dissipation for continuous USB 3.1 Gen1 operation in environments with ambient temperature swings typical of vehicle interiors and factory floors.
