TPS25944ARVCR TI eFuse Power Switch | 20-WQFN (4x3) | 5.5A, 2.7V-18V

Product Overview

The TPS25944ARVCR from Texas Instruments is a high-performance eFuse power management IC designed for robust overcurrent and overvoltage protection. Housed in a compact 20-WQFN (4x3) package, this device integrates a low on-resistance (RON) N-channel MOSFET to minimize power loss and heat dissipation. It supports a wide input voltage range from 2.7V to 18V and can deliver up to 5.5A continuous current. The TPS25944ARVCR features programmable current limit, fast short-circuit response, and thermal shutdown, making it ideal for protecting downstream circuits in various electronic systems.
