TPS25942ARVCR TI eFuse Power Switch | 20-WQFN (3x4) | 5.5A, 2.7V-18V

Product Overview

The TPS25942ARVCR is a high-performance eFuse power switch from Texas Instruments, designed to provide robust protection for power distribution systems. Housed in a compact 20-WQFN (3x4) package, this device integrates a low on-resistance (RON) N-channel MOSFET to support continuous currents up to 5.5A. It operates over a wide input voltage range of 2.7V to 18V, making it suitable for various applications including 5G base stations, industrial automation, and automotive infotainment systems. The TPS25942ARVCR offers programmable overcurrent, overvoltage, and undervoltage protection, along with thermal shutdown and reverse current blocking, ensuring reliable system operation.
