TPS25221DBVR TI Power Switch | SOT-23-6 | 2.5A, 2.7-5.5V

Product Overview

The TPS25221DBVR from Texas Instruments is a high-performance, adjustable current-limited power distribution switch designed for applications requiring robust protection and precise current control. Housed in a compact SOT-23-6 package, this device integrates a 70mΩ N-channel MOSFET with programmable current limiting up to 2.5A. It operates over a wide input voltage range of 2.7V to 5.5V, making it suitable for various low-voltage systems. The TPS25221DBVR features thermal shutdown, reverse current blocking, and under-voltage lockout (UVLO) to ensure reliable operation under fault conditions.
