The TPS2065CDGNR-2 is a sophisticated USB power distribution switch from the reputable manufacturer, Texas Instruments. Designed to enhance power management in a variety of USB applications, this component is particularly suitable for self-powered and bus-powered USB hubs, as well as other hot-swap applications.

This device is a single channel, current-limited, power distribution switch optimized for USB applications. It operates with an input voltage range of 2.7V to 5.5V, which makes it compatible with a wide array of USB devices and ensures compliance with the USB voltage specifications.

One of the key features of the TPS2065CDGNR-2 is its 210mΩ high-side MOSFET, which provides current limiting to prevent damage to host devices from over-current conditions. The switch's fast response to fault conditions protects downstream devices effectively. Additionally, it has an auto-retry feature that attempts to reset the switch after a fault condition, enhancing the reliability of the USB port.

The TPS2065CDGNR-2 also incorporates thermal shutdown protection, which prevents the chip from overheating during over-current or short-circuit conditions. This feature ensures the longevity of the switch and the safety of the USB system. Moreover, the device is capable of handling up to 1A of continuous current, which is sufficient for most USB peripherals.

Its packaging is the MSOP-8 (DGN), which is compact and suitable for space-constrained applications. The device also offers a fault status flag, which provides a real-time indication of the operational status, and an enable input, which allows the switch to be turned on or off as needed. This makes it easy for system designers to control power distribution and implement energy-saving features.

With its built-in features and reliable performance, the TPS2065CDGNR-2 is an excellent choice for designers looking to incorporate USB power switching capabilities into their applications while maintaining safety, efficiency, and a small footprint.
