TPS2544RTER TI USB Power Switch | 16-WQFN（3X3） | 2.7-5.5V, 2.4A

Product Overview

The TPS2544RTER from Texas Instruments is a high-performance USB power switch with integrated D+/D− short-circuit protection and a programmable current limit up to 2.4 A. Designed for USB host ports and charging applications, it features a 2.7 V to 5.5 V input voltage range and a low on-resistance (70 mΩ typical) to minimize power dissipation. The device is housed in a compact 16-pin WQFN (3 mm × 3 mm) package, making it ideal for space-constrained designs.
