TUSB4041IPAPRQ1

Controllers Overview

The TUSB4041IPAPRQ1 is a USB 2.0 hub controller manufactured by Texas Instruments, designed for automotive applications under the AEC-Q100 qualification standard. It integrates four high-speed transceivers and supports data rates up to 480 Mbit/s. The device operates on dual power supplies of 1.1 V and 3.3 V, with an operating temperature range from -40°C to +85°C. It is housed in a 64-pin HTQFP package measuring 10.2 x 10.2 x 1.05 mm. Key electrical characteristics include built-in ESD protection and SMBus configuration capabilities for port control.

Controllers Feature Summary

• Integrates four USB 2.0 high-speed transceivers within a single compact package
• Supports SMBus interface for dynamic configuration of downstream ports
• Includes integrated ESD protection for enhanced signal integrity
• Features independent power switch control for each downstream port

Controllers Applications

• Automotive infotainment systems requiring multiple USB connections
• In-vehicle networking hubs for passenger connectivity
• Industrial controllers needing robust USB expansion interfaces

Controllers Procurement Notes

Verify the specific suffix 'RQ1' indicates tape-and-reel packaging and automotive grade qualification. Confirm the HTQFP-64 package dimensions match the target PCB footprint. Ensure the design supports the required 1.1V and 3.3V dual-supply rails. Validate that the host system provides the necessary SMBus lines for configuration.

Controllers Selection Notes

Select this component when a single-chip solution for four USB 2.0 ports is required in space-constrained designs. It is suitable for applications demanding AEC-Q100 reliability. Consider the 64-pin HTQFP package constraints during layout. Verify compatibility with the host processor's SMBus or I2C interface for proper initialization.

Controllers Part Context

This part belongs to the TUSB4041 family of USB 2.0 hub controllers. The 'IPAPRQ1' designation specifies the industrial/automotive temperature range, HTQFP package, and reel packaging. It serves as a bridge between a host controller and multiple USB peripherals, simplifying board design by integrating transceivers and power management logic.

Controllers Replacement Considerations

TUSB4041IPAP: Identical functional specifications but in tube packaging instead of tape-and-reel. Suitable if reflow profile and handling procedures accommodate tube components without altering the circuit design.
