USB5807-I/KD

Controllers Overview

The USB5807-I/KD is a low-power, OEM-configurable USB 3.1 Gen 1 hub controller featuring seven downstream ports. It supports Super-Speed (5 Gbps), Hi-Speed (480 Mbps), Full-Speed (12 Mbps), and Low-Speed (1.5 Mbps) data rates. The device operates within a supply voltage range of 1.08 V to 3.6 V and functions at working voltages of 1.2 V and 3.3 V. It is housed in a 100-pin VQFN package measuring 12 mm x 12 mm. The industrial grade variant supports an operating temperature range from -40°C to +85°C.

Controllers Feature Summary

• Supports USB-IF Battery Charging revision 1.2 with DCP, CDP, and SDP profiles on upstream and downstream ports.
• Includes FlexConnect functionality allowing downstream port 1 to swap roles with the upstream port for master-capable devices.
• Offers enhanced OEM configuration via configuration straps, OTP ROM, or external SPI ROM without requiring firmware.
• Integrates PHYBoost for programmable drive strength and VariSense for adjustable receive sensitivity to maintain signal integrity.

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 against official Microchip documentation to confirm temperature range and package details. Ensure compatibility with system power requirements and interface standards before integration. Cross-reference part numbers with authorized distributors to avoid counterfeit components.

Controllers Selection Notes

Select this component for designs requiring seven high-speed downstream connections with flexible port management. Consider the industrial temperature rating for harsh environments. Evaluate the need for battery charging support and OEM configurability options during the design phase.

Controllers Part Context

This model belongs to the Microchip USB5807 family of USB hub controllers. It shares core architecture with commercial variants but differs in operational temperature specifications. The series provides a scalable solution for embedded USB applications requiring robust connectivity and power management features.

Controllers Replacement Considerations

Direct substitutes include other USB5807 variants such as USB5807C/KD for commercial temperature ranges. Verify pinout and electrical characteristics match before substitution. Consult Microchip for updated recommendations if discontinuation occurs.

Controllers FAQ

How does FlexConnect operate on the USB5807?

FlexConnect allows Port 1 to be reconfigured as the upstream port, enabling master-capable devices connected to it to control other devices on the hub.

What battery charging standards are supported?

The device supports USB-IF Battery Charging Revision 1.2, including Dedicated Charging Port (DCP), Charging Downstream Port (CDP), and Standard Downstream Port (SDP).

Can the USB5807 be configured without external memory?

Yes, OEMs can use configuration straps to set default values for ports and GPIOs, eliminating the immediate need for OTP or SPI ROM for basic operation.
