The TPS2051BDGNRG4 is a state-of-the-art power distribution switch designed by Texas Instruments, tailored for USB and other power applications. This device is a single-channel, current-limited, power-distribution switch optimized for self-powered and bus-powered Universal Serial Bus (USB) applications.

Key Features

• Integrated Fault Protection: The TPS2051BDGNRG4 is equipped with over-current protection to safeguard USB ports and downstream devices from damage due to excessive current draw.
• Thermal Shutdown: An integrated thermal shutdown feature prevents overheating, enhancing the longevity and reliability of both the switch and the system it protects.
• Controlled Rise Time: The device ensures a controlled rise time, reducing inrush current which can be beneficial for sensitive equipment and helps in meeting USB specifications.
• Under-Voltage Lockout (UVLO): This feature ensures that the switch remains off when the supply voltage is too low, thus protecting the device and the system.

Applications

The TPS2051BDGNRG4 is versatile and can be used in a variety of applications, including:

• USB hubs, peripherals, and monitors
• Battery-charger circuits
• Power distribution for consumer electronics

Technical Specifications

With an input voltage range of 2.7V to 5.5V, the TPS2051BDGNRG4 is suitable for most low-voltage applications. The switch can handle continuous output currents up to 1A, and its low on-resistance of 70mΩ ensures minimal voltage drop and power loss. The device is offered in an 8-pin MSOP (DGN) package, which is compact and suitable for space-constrained applications.
