USB5916T/KD

Controllers Overview

The USB5916T/KD is a low-power, OEM-configurable USB 3.1 Gen 1 hub controller featuring six downstream ports and native USB Type-C support. It integrates one USB Type-C downstream port, four legacy USB 3.1 Gen 1 ports, and one USB 2.0 legacy port, alongside a USB Type-C upstream interface. The device supports SuperSpeed (5 Gbps), Hi-Speed (480 Mbps), Full-Speed (12 Mbps), and Low-Speed (1.5 Mbps) operations. Key capabilities include USB-IF Battery Charging revision 1.2 compliance, Link Power Management (LPM), and an internal Hub Feature Controller for I2C/SPI/GPIO bridging. Configuration is managed via configuration straps, OTP ROM, or external SPI ROM.

Controllers Feature Summary

• Native USB Type-C support with integrated multiplexer and automatic PHY enablement upon valid attachment detection to optimize power consumption.
• Smart port controller operation with firmware-managed companion port power controllers and configurable PortSwap for differential pair alignment.
• Comprehensive battery charging support including USB-IF BC1.2 profiles (DCP, CDP, SDP) and emulation for Apple and Chinese/European standards.
• Signal integrity enhancement features including programmable PHYBoost drive strength and VariSense receiver sensitivity control.

Controllers Applications

• Standalone USB Hubs
• Laptop Docks
• PC Motherboards
• PC Monitor Docks
• Multi-function USB 3.1 Gen 1 Peripherals

Controllers Procurement Notes

Verify component authenticity through authorized Microchip Technology distributors or direct channels. Confirm the specific suffix 'KD' matches the required package and temperature grade specifications. Review the official datasheet DS00002243D for detailed pinout and electrical characteristics before integration. Ensure compliance with RoHS directives as indicated in the product documentation.

Controllers Selection Notes

Select this component for designs requiring a compact 100-pin VQFN solution with integrated USB Type-C functionality. Consider the internal Hub Feature Controller if system monitoring via USB-to-I2C/SPI bridges is needed. Evaluate the OTP and SPI ROM options for flexible OEM configuration needs without external microcontrollers. Verify thermal dissipation requirements given the optimized low-power design targets.

Controllers Part Context

The USB5916 series represents Microchip's advanced smart hub controllers designed for embedded USB applications. It combines a dedicated USB 2.0 hub controller with a parallel SuperSpeed controller to prevent traffic bottlenecks. This architecture ensures interoperability and reliability across various USB speeds while providing extensive configurability for OEMs through hardware straps and firmware.

Controllers Replacement Considerations

Publicly confirmed parameter-equivalent substitutes include the USB5906C/KD, USB5916C/KD, and USB5926C/KD from Microchip Technology. Verify pin compatibility and feature parity with the datasheet before substitution.
