USB5916T-I/KD

Controllers Overview

The USB5916T-I/KD is a low-power, OEM-configurable USB 3.1 Gen 1 hub controller featuring six downstream ports and one upstream port. It supports Super-Speed (5 Gbps), Hi-Speed (480 Mbps), Full-Speed (12 Mbps), and Low-Speed (1.5 Mbps) data rates. The device includes one USB Type-C downstream port with integrated multiplexing and one USB Type-C upstream port. It incorporates an internal Hub Feature Controller for I2C/SPI/GPIO bridging, battery charging support compliant with USB-IF BC1.2, and configuration options via OTP or SPI ROM. The component operates within commercial and industrial temperature ranges.

Controllers Feature Summary

• Integrated USB Type-C support with automatic PHY enablement upon valid attachment detection to minimize idle power consumption.
• Built-in Hub Feature Controller enabling USB-to-I2C/SPI/GPIO bridge functionality for external circuit monitoring and control.
• Supports USB-IF Battery Charging Revision 1.2 standards including DCP, CDP, and SDP profiles on all ports.
• Advanced signal integrity features including programmable drive strength (PHYBoost) and receiver sensitivity (VariSense).

Controllers Applications

• Standalone USB Hubs
• Laptop Docks
• PC Motherboards
• PC Monitor Docks
• 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 opposed to the commercial variant. Confirm package type is 100-pin VQFN. Check current availability status as distribution may vary by region. Ensure compatibility with host system voltage requirements of 1.08V to 1.32V for core logic and 3.0V to 3.6V for I/O.

Controllers Selection Notes

Select this model when native USB Type-C connectivity is required for either upstream or downstream connections. Choose over standard hubs if firmware configurability via OTP or SPI is needed for custom OEM implementations. Consider for applications requiring independent port power control or specific battery charging emulation protocols beyond standard USB specifications.

Controllers Part Context

The USB5916 belongs to Microchip's Smart Hub family, designed for embedded USB applications. It decouples SuperSpeed data transfers from USB 2.0 traffic bottlenecks using parallel controllers. The device integrates an on-chip microcontroller managing I/Os and VBUS signals, offering enhanced flexibility compared to basic hub controllers through extensive GPIO availability and configurable strap settings.

Controllers Replacement Considerations

Public confirmed substitutes include USB5906C/KD and USB5916C/KD. Note that the 'C' suffix denotes commercial temperature range (0°C to +70°C), whereas the 'I' suffix in USB5916T-I/KD specifies industrial range (-40°C to +85°C). Verify thermal requirements before substitution.
