Texas Instruments TUSB2046IBVF USB Hub Controller

The TUSB2046IBVF from Texas Instruments is a versatile USB hub controller that integrates a USB 2.0 transceiver and a Serial Interface Engine (SIE) with a 4-port hub logic, making it an ideal choice for creating USB connectivity solutions. This integrated circuit is designed to extend the capabilities of a single USB port, allowing for the connection of up to four additional USB devices.

Featuring full compliance with the USB 2.0 specification, the TUSB2046IBVF supports low-speed (1.5 Mbps) and full-speed (12 Mbps) data rates, ensuring compatibility with a wide range of USB peripherals. Its high-quality design includes built-in 3.3V voltage regulators, which allow the device to operate from a single 5V supply, simplifying the power management in USB systems.

The TUSB2046IBVF is housed in a compact 32-pin LQFP (Low-Profile Quad Flat Package) that minimizes the footprint on the PCB and is suitable for space-constrained applications. Additionally, it features overcurrent reporting for each downstream port, providing enhanced protection for connected devices. The hub controller also supports both individual and ganged power switching and overcurrent detection, giving designers flexibility in managing power distribution and safety features.

With its integrated upstream 1.5kΩ pull-up resistor and downstream 15kΩ pull-down resistors, the TUSB2046IBVF ensures proper USB signaling and simplifies external component requirements. The device also includes an optional port power control, which allows for the management of port power without the need for external components, making it a user-friendly and cost-effective solution for USB hub design.

Designed with ease of use in mind, the TUSB2046IBVF is plug-and-play and hot-swappable, which means devices can be connected or disconnected without the need to power down or restart the host system. The hub controller is perfect for a wide range of applications, including desktop and laptop computers, docking stations, monitors with USB ports, and standalone USB hubs.

Overall, the TUSB2046IBVF from Texas Instruments is a robust and reliable choice for designers looking to expand USB capabilities with a high-performance, integrated hub controller solution.
