TPS2543RTET TI USB Power Switch | 16-WQFN (3X3) | 2.7A, 2.7V-5.5V

Product Overview

The TPS2543RTET from Texas Instruments is a high-performance USB power switch with integrated overcurrent protection and a programmable current limit up to 2.7A. Housed in a compact 16-WQFN (3x3mm) package, it operates over a wide input voltage range of 2.7V to 5.5V, making it ideal for USB ports and other power distribution applications. The device features a low on-resistance (70mΩ typical) to minimize power loss and supports reverse current protection when disabled.
