USB7051/KDX

Controllers Overview

The USB7051/KDX is a four-port USB 3.2 Gen 1 hub controller manufactured by Microchip Technology, designed for industrial applications with an operating temperature range of -40°C to +85°C. It integrates native Type-C upstream ports and supports Power Delivery (PD) negotiation. The device features two downstream Type-C ports with CC pin support alongside traditional Type-A ports. Packaged in a 100-VQFN (12x12 mm) housing with exposed pad, it operates on supply voltages between 1.2 V and 3.6 V. The component complies with AEC-Q100 automotive qualification standards and RoHS3 directives.

Controllers Feature Summary

• Integrates native Type-C upstream connectivity with built-in Power Delivery protocol handling capabilities.
• Supports mixed downstream port configurations including Type-C with CC pin detection and standard Type-A interfaces.
• Engineered for industrial-grade reliability with extended temperature operation from -40°C to +85°C.
• Provides GPIO, I2C, SPI, and UART interface options for flexible system integration.

Controllers Applications

• Industrial automation controllers requiring robust USB connectivity in harsh environments.
• Automotive infotainment systems and telematics units needing PD-enabled charging ports.
• Medical equipment requiring certified interface hubs with extended thermal stability.
• Ruggedized computing platforms utilizing mixed legacy and modern USB connector types.

Controllers Procurement Notes

Verify the specific suffix designation against official Microchip documentation to confirm package type and temperature grade. Confirm current lifecycle status as distribution listings may indicate end-of-life or discontinuation phases. Ensure compatibility with required PCB footprint dimensions for the 100-VQFN package during procurement planning.

Controllers Selection Notes

Select this component when native Type-C upstream functionality with integrated Power Delivery negotiation is required without external controllers. Consider the industrial temperature rating for deployments exceeding commercial limits. Evaluate the 100-VQFN package constraints against available board space and thermal dissipation requirements for the target application design.

Controllers Part Context

This part belongs to the USB70xx series of smart hubs from Microchip Technology, which focus on integrating Type-C and Power Delivery capabilities directly into the hub controller architecture. The KDX suffix typically denotes the specific tape-and-reel or tray packaging configuration and temperature grade variant within the broader product family.
