STEF512PUR ST Power Switch | 10-QFN (2x3) | 5.5V, 2A, 85mΩ

Product Overview

The STEF512PUR is an advanced electronic fuse from STMicroelectronics, designed for overcurrent and overvoltage protection in power distribution systems. Housed in a compact 10-QFN (2x3) package, it integrates a low-resistance power switch (85mΩ typical) with precise current limiting and thermal shutdown. Operating from 2.7V to 5.5V, it supports continuous currents up to 2A, making it ideal for space-constrained applications requiring robust protection.
