STEF05SGR ST Power Switch | 10-VFDFN 祼焊盘 | 5A, 2.7-18V

Product Overview

The STEF05SGR is a fully integrated 5A power switch from STMicroelectronics, designed for hot-swap and overcurrent protection in high-reliability applications. Housed in a compact 10-VFDFN exposed pad package, it offers a wide input voltage range from 2.7V to 18V, making it suitable for various power distribution systems. The device integrates a low on-resistance N-channel MOSFET (typically 30mΩ) to minimize power loss, along with programmable current limiting, thermal shutdown, and under-voltage lockout (UVLO) for robust protection.
