TPS259521DSGR TI eFuse | 8-WSON (2x2) | 5.5V, 5A, 28mΩ

Product Overview

The TPS259521DSGR from Texas Instruments is a high-performance eFuse power management IC designed for robust overcurrent and overvoltage protection. Housed in a compact 8-WSON (2x2 mm) package, it integrates a 28mΩ on-resistance N-channel MOSFET to support up to 5A continuous current. With an input voltage range of 2.7V to 5.5V, it is ideal for space-constrained applications requiring precise current limiting and fast transient response.
