TITUSB4041IPAPR
Overview
The TUSB4041IPAPR is a four-port USB 2.0 hub controller designed for high-performance and low-power applications. It features a Multi Transaction Translator (MTT) architecture that ensures maximum throughput when multiple Full-Speed (FS) devices are connected concurrently. The device supports battery charging and offers multiple configuration options through I2C, SMBus, or an external EEPROM.
Why Choose This Part
The MTT architecture prevents bandwidth bottlenecks common in Single Transaction Translator hubs when mixing High-Speed and Full-Speed devices. It offers extreme flexibility with on-board OTP ROM and I2C/SMBus slave interfaces for custom PID/VID and configuration without external components. Additionally, it features low power consumption with a typical run current of 76mA when supporting four High-Speed devices.
Applications
Key Specifications
Getting Started
Designers should refer to the TUSB4041EVM evaluation module for a reference hardware layout. Configuration can be performed via hardware strap pins for simple designs or through the I2C interface for advanced custom descriptors. Ensure the 1.1V and 3.3V supply rails are properly decoupled and the thermal pad of the 64-HTQFP package is soldered to a solid ground plane for heat dissipation.
