TPS2557QDRBTQ1 TI Power Switch | 8-SON(3x3) | 2.5A, 2.7-5.5V

Product Overview

The TPS2557QDRBTQ1 is a automotive-grade, current-limited power-distribution switch from Texas Instruments. It features a 70mΩ N-channel MOSFET, operates over an input voltage range of 2.7V to 5.5V, and can deliver up to 2.5A of continuous current. The device integrates over-current, over-temperature, reverse-current, and short-circuit protection, making it ideal for robust power management in automotive and industrial applications.
