TPS259472LRPWR TI eFuse | 10-VQFN-HR (2x2) | 5.5V, 4A, 28mOhm

Product Overview

The TPS259472LRPWR is a high-performance eFuse (electronic fuse) from Texas Instruments, designed for robust power path protection in space-constrained applications. Housed in a compact 10-pin VQFN-HR package (2mm x 2mm), this device integrates a low on-resistance (28mΩ typical) N-channel MOSFET to provide accurate current limiting, overvoltage protection, and reverse current blocking. With an input voltage range of 2.5V to 5.5V and a continuous current rating of 4A, it is ideal for hot-swap, USB, and point-of-load applications.
