USB4604I-1080HN

Overview

The USB4604I-1080HN is a low-power, OEM-configurable Multi-Transaction Translator (MTT) USB 2.0 hub controller featuring four downstream ports and an upstream interface selectable between High-Speed Inter-Chip (HSIC) or standard USB 2.0. It supports Hi-Speed data rates up to 480 Mbps and includes integrated battery charger detection compliant with USB-IF BC1.2 standards. The device operates within an industrial temperature range of -40°C to +85°C and utilizes a 48-pin SQFN package measuring 7x7mm. Power supply requirements include VBAT, VDD33, and VDDCOREREG.

Feature Summary

• Supports FlexConnect functionality allowing Downstream Port 1 to swap with the Upstream port for master-capable device control.
• Integrates MultiTRAK technology providing dedicated Transaction Translators per port to maintain full-speed throughput.
• Includes programmable PHYBoost and VariSense features to restore signal integrity and adjust receiver sensitivity.
• Features built-in USB-to-I2C/SPI bridge endpoint support for external circuit monitoring and configuration.

Applications

• LCD monitors and TVs
• Multi-function USB peripherals
• PC motherboards
• Set-top boxes, DVD players, DVR/PVR
• Printers and scanners

Procurement Notes

Verify the specific ordering suffix '1080' confirms the internal Hub Controller is enabled, as opposed to the '-1070' variant which disables it. Ensure compatibility with the required 48-SQFN footprint and confirm that the industrial temperature grade (-40°C to +85°C) meets the target system's environmental specifications before finalizing procurement.

Selection Notes

Select this component when embedded designs require flexible connectivity options such as HSIC or USB 2.0 upstream interfaces. It is suitable for applications needing advanced power management via individual port control and battery charging detection. Consider the integrated termination resistors and regulators if minimizing external BOM components is a priority.

Part Context

This part belongs to the USB4604 series from Microchip Technology. The 'I' suffix denotes the industrial temperature range version (-40°C to +85°C), distinguishing it from commercial variants. The '1080' firmware revision specifically enables the onboard Hub Controller functionality, allowing host commands to be sent directly to the device via the virtual fifth port.

Replacement Considerations

The USB4624-1080HN is a related model offering similar 4-port capabilities but typically targets commercial temperature ranges. Verify pinout compatibility and firmware feature sets, particularly regarding the Hub Controller enablement, when evaluating substitutes.
