Product Overview: Texas Instruments TPS2061D

The TPS2061D is a robust, single-channel, current-limited integrated power switch from Texas Instruments, designed for USB and other applications where heavy capacitive loads and short-circuits are likely to be encountered. This device is part of TI's extensive power management portfolio and is specifically tailored to provide a reliable power distribution solution.

Key Features

• Current Limiting: The TPS2061D offers a precise current-limiting function, which protects the source from excessive current draw. This is essential for USB power distribution as it ensures the USB host or hub port is safeguarded against overcurrent conditions.
• Over-Temperature Protection: With built-in over-temperature protection, the device automatically shuts down if it overheats, providing an additional layer of safety for the connected load and power source.
• Fast Transient Response: The device is engineered to handle fast transients, which is critical when managing the inrush current associated with capacitive loads.
• Reverse Voltage Protection: The TPS2061D includes a feature to protect against reverse voltage, which helps prevent damage to the power switch if the voltage is accidentally applied in the wrong polarity.

Applications

With its versatile design, the TPS2061D is suitable for a variety of applications, including:

• USB hubs and peripherals
• Hot-swap supplies
• Power distribution switches

Technical Specifications

• Output Current: The device supports up to 1 A of continuous current.
