TPS2061DBVR Single Channel USB Power Distribution Switch

The TPS2061DBVR from Texas Instruments is a versatile, high-quality power distribution switch specifically designed for USB applications. This compact and efficient device is housed in a 5-pin SOT-23 package, making it an ideal choice for space-constrained applications. The TPS2061DBVR allows a USB port to supply up to 1.5A of continuous current to downstream devices while providing protection features to ensure the stability and safety of the system.

One of the key features of the TPS2061DBVR is its integrated over-current protection, which safeguards the USB port from excessive current that could potentially damage the host device or the peripheral. Additionally, the device includes thermal shutdown protection, which automatically turns off the switch if it overheats, thereby preventing thermal damage.

This power switch also supports a wide operating voltage range from 2.7V to 5.5V, making it suitable for a variety of USB-powered devices and applications. Its low on-resistance (typically 70mΩ) ensures minimal voltage drop and power loss, which is critical for maintaining efficient power distribution in USB systems.

The TPS2061DBVR also features a built-in charge pump that reduces the number of external components required, thus simplifying design and reducing overall system cost. The charge pump supports the drive for an N-channel MOSFET, which acts as the power-distribution switch, providing a compact and efficient solution for USB power management.

For designers looking for a reliable and robust USB power distribution solution, the TPS2061DBVR offers fault status reporting through an open-drain fault output pin. This feature allows for immediate system response to fault conditions, enhancing system reliability.

Whether you are designing USB hubs, docking stations, or portable devices, the TPS2061DBVR is an excellent choice for managing power with confidence. Its combination of protection features, high current capability, and small form factor make it a go-to component for USB power distribution needs.
