TPS25921AD TI eFuse Power Switch | 8-SOIC | 5.5V, 5A, Adjustable Current Limit

Product Overview

The TPS25921AD from Texas Instruments is a compact, feature-rich eFuse power switch designed for robust protection of power distribution systems. Housed in an 8-SOIC package, this device integrates a low on-resistance N-channel MOSFET with a comprehensive set of protection features including overcurrent, overvoltage, undervoltage, and thermal shutdown. It supports a wide input voltage range from 2.7V to 5.5V and can deliver up to 5A continuous current. The adjustable current limit allows designers to tailor the protection threshold to specific application needs, making it ideal for hot-swap, USB, and general power management applications.
