Descripción general

Description

The TUSB1044IRNQT is a Texas Instruments USB 2.0 four-port hub controller. It provides one upstream USB port to a host and four downstream ports for peripherals, enabling you to add multiple USB devices to a system.
Key points:
- USB 2.0 High-Speed (up to 480 Mbps) hub with one upstream and four downstream ports
- Integrated per-port power switches and overcurrent protection
- Supports bus-powered or self-powered hub configurations
- Includes hub management features (status/reporting to host)
IRNQT is TI’s packaging/version code (package type, lead-free, and/or temperature grade). For exact packaging, temperature range, and availability, check the TI product page and datasheet.

Features

Here are the key features of TUSB1044IRNQT (USB Type-C 4-port hub):
- 1 upstream USB Type-C port to host and 4 downstream USB-C ports
- USB 3.1 Gen1 data rate up to 5 Gbps; backward compatible with USB 2.0
- Type-C orientation-agnostic operation via integrated CC logic
- I2C control interface for port enable/disable, reset, and status
- Per-port power switches with overcurrent protection
- ESD protection on all data and CC lines
- Hot-plug capable with automatic enumeration and suspend/resume
- Low-power operation suitable for embedded/consumer systems
- Tiny package (IRNQT) with standard TI manufacturing options
Note: For exact electrical specs, current limits, and layout guidelines, please refer to the official datasheet.

Package

16-pin QFN package (VQFN-16, 3x3 mm).

Pinout

Pin count: 40 pins (QFN). Function: USB Type-C port controller with a high-speed crossbar switch, used to route USB 3.x SuperSpeed pairs between Type-C ports and handle CC orientation/negotiation.
