TPS2540RTER TI USB Power Switch | 16-WQFN（3X3） | 2.7-5.5V, 2.5A

Product Overview

The TPS2540RTER from Texas Instruments is a high-performance USB power switch with integrated overcurrent protection and a programmable current limit up to 2.5 A. It operates from a 2.7 V to 5.5 V input voltage range and features a low on-resistance (70 mΩ typical) to minimize power dissipation. The device is designed for USB applications requiring robust protection and precise current limiting, such as USB hubs, docking stations, and portable electronics. Housed in a compact 16-WQFN (3x3 mm) package, it offers a space-saving solution for modern designs.
