The TPS2068DGN is a robust, feature-rich USB power distribution switch from Texas Instruments, designed for applications where heavy capacitive loads and short circuits may be encountered. This power switch is optimized for managing power distribution to USB ports and is housed in a compact 8-pin MSOP (DGN) package, making it an excellent choice for space-constrained applications.

Key Features

• Multiple USB Port Support: The TPS2068DGN can support up to 1.5A of continuous current across multiple USB ports, making it ideal for hubs and other devices that need to power several peripherals.
• Overcurrent Protection: It features built-in overcurrent protection to safeguard the device and downstream components from damage due to excessive current draw.
• Thermal Shutdown: The device includes a thermal shutdown feature that protects against overheating, ensuring reliable operation under varying conditions.
• Under-Voltage Lockout (UVLO): The UVLO function ensures that the switch remains off if the input voltage is too low, preventing erratic behavior of connected devices.
• Fast Overcurrent Response: With a quick response time to overcurrent conditions, the TPS2068DGN helps to minimize the risk of system damage.

Applications

The TPS2068DGN is versatile and can be used in a variety of applications, including but not limited to:

• USB Hubs
• Desktop and Notebook Computers
• Docking Stations
• Monitors with USB Ports
• Peripheral Power Management

Technical Specifications

With an input voltage range of 2.7V to 5.5V, the TPS2068DGN is suitable for both 3.3V and 5V systems. Its low standby current makes it an energy-efficient choice for modern electronic devices. The device also offers a fault report (FAULT) output, which provides a signal to the host controller when an overcurrent event occurs.

For designers and engineers looking for a reliable power distribution solution, the TPS2068DGN from Texas Instruments stands out as a high-performance option that can enhance the safety and stability of USB-powered systems.
