TUSB8043AIRGCT

Controllers Overview

The TUSB8043AIRGCT is a four-port USB 3.2 Gen 1 hub controller manufactured by Texas Instruments, housed in a 64-VQFN package. It supports Super Speed data rates of 5 Gb/s and operates within an extended industrial temperature range of -40°C to +85°C. The device requires dual power supplies: a minimum voltage of 990 mV and a maximum of 3.6 V, with typical operating voltages at 1.1 V and 3.3 V. It features I2C interface control and maintains a low standby current of 15 uA. This component is designed for applications requiring robust USB connectivity with integrated Human Interface Device (HID) support capabilities.

Controllers Feature Summary

• Supports four independent downstream ports compliant with USB 3.2 Gen 1 standards
• Integrates dedicated hardware logic for Human Interface Device (HID) passthrough functionality
• Operates across the full industrial temperature spectrum from -40°C to +85°C

Controllers Applications

• Industrial computing systems requiring reliable USB expansion in harsh environments
• Embedded host controllers needing direct HID device connectivity without software overhead
• Portable electronic devices utilizing USB 3.2 Gen 1 peripheral connections

Controllers Procurement Notes

Verify the specific suffix 'AIRGCT' to confirm the industrial temperature grade (-40°C to +85°C) and reel packaging format. Ensure compatibility with I2C control lines and check moisture sensitivity level requirements during storage and handling. Confirm that the design supports the required 1.1 V and 3.3 V power domains before procurement.

Controllers Selection Notes

Select this model when an industrial-grade temperature rating is mandatory compared to commercial variants like the TUSB8043RGCT. Choose this part if the application specifically requires integrated HID support features rather than standard hub-only functionality. Verify that the 64-VQFN footprint fits the target PCB layout constraints.

Controllers Part Context

This component belongs to the TUSB804x series of USB hub controllers from Texas Instruments. It serves as an advanced iteration within the family, distinguished by its extended temperature range and specialized HID integration. It complements other models such as the TUSB8041 and TUSB8042 by offering specific feature sets tailored for complex embedded interfaces.

Controllers Replacement Considerations

The TUSB8043RGCT is a commercial-grade alternative with a 0°C to +70°C range. The TUSB8041IRGCT offers similar port counts but lacks the specific HID integration features documented for the AIR variant.
