The TPS2071DAP is a versatile single-channel USB power distribution switch designed by Texas Instruments, engineered to enhance power management solutions in USB hubs and other applications where distribution and protection are required. This device is particularly suitable for both self-powered and bus-powered USB hubs, monitors, docking stations, and other peripherals.

Key Features

• Integrated Single Channel: The TPS2071DAP features a single channel for USB power distribution, making it ideal for simple applications or as part of a larger USB hub design.
• Current-Limiting Protection: It includes a built-in 0.5A current-limiting protection to safeguard USB ports and downstream devices from excessive current draw that can lead to damage or system instability.
• Thermal Shutdown: The device also offers thermal shutdown protection, which prevents overheating by automatically turning off the power switch if the die temperature exceeds a safe threshold.
• Under-Voltage Lockout (UVLO): The UVLO feature ensures that the switch remains off if the input voltage is too low, which protects the device and the connected peripherals from operating under potentially harmful low-voltage conditions.
• Fast Overcurrent Response: With a swift response to overcurrent conditions, the TPS2071DAP quickly responds to protect the circuitry by limiting the output current.
• Status Flag: An open-drain status flag output provides a real-time signal to the host when an overcurrent, thermal shutdown, or UVLO event occurs.
• Controlled Rise Time: The switch ensures a controlled rise time to reduce inrush current, which is critical for managing power-up sequences in sensitive electronics.

Applications

The TPS2071DAP is an ideal solution for a variety of applications that require power distribution with a protective mechanism. It is commonly used in:

• USB Hubs
