USB5807/KD

Controllers Overview

The USB5807/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 voltage range of 1.08 V to 3.6 V and functions across commercial (0°C to +70°C) and industrial (-40°C to +85°C) temperature ranges. It integrates battery charging detection for USB-IF BC1.2 profiles and includes an on-chip microcontroller with 8 KB RAM and 64 KB ROM.

Controllers Feature Summary

• Supports USB-IF Battery Charging revision 1.2 standards including DCP, CDP, and SDP profiles on upstream and downstream ports.
• Features FlexConnect capability allowing Port 1 to swap roles with the upstream port for master-controlled hub configurations.
• Includes PHYBoost and VariSense technologies for programmable signal drive strength and receive sensitivity to maintain integrity in compromised environments.
• Enables OEM configuration via configuration straps, OTP ROM, or external SPI ROM without requiring firmware updates.

Controllers Applications

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

Controllers Procurement Notes

Verify component authenticity by checking the manufacturer's marking against official datasheet specifications. Confirm package integrity and pin alignment prior to installation. Ensure compliance with RoHS directives and moisture sensitivity levels during storage and handling procedures.

Controllers Selection Notes

Select this controller for designs requiring seven downstream ports with independent power control and battery charging support. Consider the 100-pin VQFN package dimensions for PCB layout constraints. Evaluate thermal dissipation requirements based on the specific application's power budget and ambient operating conditions.

Controllers Part Context

This component belongs to Microchip Technology's USB interface integrated circuit family. It serves as a central hub controller for managing multiple USB devices. The device replaces older generation controllers by offering higher data rates and enhanced power management features suitable for modern embedded systems.

Controllers Replacement Considerations

Public confirmed substitute part numbers include USB5826C/KD, USB5906C/KD, USB5916C/KD, and USB5926C/KD. Verify pin compatibility and feature parity before substitution.

Controllers FAQ

How does the FlexConnect feature function?

FlexConnect allows one of the downstream ports (Port 1) to be reconfigured as the upstream port. This enables master-capable devices connected to the hub to control other devices attached to the hub.

What battery charging standards are supported?

The USB5807 supports USB-IF Battery Charging revision 1.2, including Dedicated Charging Port (DCP), Charging Downstream Port (CDP), and Standard Downstream Port (SDP) profiles.

Can the device operate without external memory?

Yes, the device can operate using internal default settings or configuration straps. Enhanced OEM configurations can also be loaded via 8 KB One-Time-Programmable (OTP) ROM or external SPI ROM.
