TUSB8041IRGCT

Controllers Overview

The TUSB8041IRGCT is a four-port USB 3.0 hub controller manufactured by Texas Instruments, designed for SuperSpeed (SS) data transmission at rates up to 5 Gb/s. It operates within a voltage range of 990 mV to 3.6 V and draws a typical operating supply current of 28 mA. The device supports an extended industrial temperature range from -40°C to +85°C and is housed in a compact VQFN-64 surface-mount package. It integrates I2C and SMBus interface capabilities for configuration and control, facilitating efficient integration into high-speed peripheral expansion systems.

Controllers Feature Summary

• Supports four independent downstream ports for simultaneous connection of multiple USB devices
• Enables high-speed data transfer compliant with USB 3.0 SuperSpeed standards
• Provides flexible power management and port control through serial interface commands

Controllers Applications

• Desktop and laptop computer peripheral expansion docks
• Industrial automation controllers requiring robust USB connectivity
• Embedded systems needing multi-device USB host functionality

Controllers Procurement Notes

Verify the specific suffix IRGCT to confirm the VQFN-64 package and cut tape delivery format. Confirm that the component meets the required -40°C to +85°C operating temperature range for your application environment. Ensure compatibility with the system's I2C/SMBus logic levels before integration.

Controllers Selection Notes

Select this model when a four-port SuperSpeed solution is required in a small form factor. Compare against the TUSB8040 series if a different pinout or package size like WQFN-100 is preferred. Verify that the 28 mA active current consumption aligns with the system's power budget constraints.

Controllers Part Context

This component belongs to the TUSB8041 family of USB 3.0 hub controllers. It serves as a direct upgrade path for legacy USB 2.0 hubs, offering significantly higher bandwidth. The IRGCT variant specifically denotes the commercial/industrial grade version in the VQFN-64 package, distinct from automotive-grade Q1 variants.

Controllers Replacement Considerations

The TUSB8041IRGCR is a reel-based alternative with identical electrical characteristics. For pin-compatible upgrades, consider the TUSB8040ARKMT, though it utilizes a larger WQFN-100 package.
