TPS259571DSGR TI eFuse | 8-WSON (2x2) | 2.7V-18V, 5A, 28mOhm

Product Overview

The TPS259571DSGR is a high-performance eFuse power management IC from Texas Instruments, designed for robust circuit protection in space-constrained applications. Housed in a compact 8-WSON (2x2 mm) package, this device integrates a low on-resistance (28 mΩ) N-channel MOSFET to provide accurate current limiting, overvoltage protection, and reverse current blocking. It operates over a wide input voltage range of 2.7 V to 18 V and supports continuous load currents up to 5 A. The TPS259571DSGR is ideal for hot-swap, USB, and general-purpose power rail protection in industrial, automotive, and consumer electronics.
