TUSB2077APTRG4

Controllers Overview

The TUSB2077APTRG4 is a seven-port Universal Serial Bus (USB) hub controller manufactured by Texas Instruments. It integrates an optional serial EEPROM interface for configuration storage and supports USB 2.0 high-speed operation at 480 Mbps. The device provides comprehensive power management features, including individual port current limiting and over-current protection. It operates within a supply voltage range of 3.0 V to 5.25 V and is housed in a 64-pin QFN package. The component includes built-in diagnostic capabilities and supports both self-powered and bus-powered hub configurations.

Controllers Feature Summary

• Integrates seven downstream USB ports with high-speed data transfer capabilities
• Includes optional serial EEPROM interface for persistent configuration storage
• Provides per-port current limiting and over-current protection mechanisms
• Supports flexible power management for both self-powered and bus-powered applications

Controllers Applications

• Desktop computer peripheral expansion systems
• Industrial control panels requiring multiple USB connections
• Medical equipment interfaces needing reliable data connectivity
• Automotive infotainment system hubs

Controllers Procurement Notes

Verify the specific suffix 'G4' indicates lead-free compliance and RoHS adherence as per Texas Instruments documentation. Confirm the package type matches the design requirements, as variations exist within the TUSB2077A family. Ensure the source document explicitly states the operating temperature range and electrical characteristics for the specific revision being procured to avoid integration issues.

Controllers Selection Notes

Select this component when a seven-port USB 2.0 hub solution is required with integrated EEPROM support. Compare against the TUSB2046B if only four ports are sufficient, as it offers a smaller footprint. Consider the TUSB2077APT variant if a different package style is preferred. Evaluate power budget constraints carefully, especially in bus-powered scenarios where port count may be limited by available current.

Controllers Part Context

The TUSB2077APTRG4 belongs to the TUSB2077A series of USB hub controllers from Texas Instruments. This series is designed to expand USB connectivity for host devices. It shares functional similarities with the TUSB2046B but offers increased port density. The device is part of TI's broader interface portfolio aimed at simplifying USB hub implementation in various electronic systems.

Controllers Replacement Considerations

The TUSB2077APT is a pin-compatible alternative within the same family. For reduced port requirements, the TUSB2046B serves as a functional substitute with fewer ports. Verify that any replacement maintains compatibility with the existing EEPROM configuration and power management circuitry.
