TPS2049DR TI Power Switch | 8-SOIC | 0.5A, 2.7-5.5V

Product Overview

The TPS2049DR from Texas Instruments is a single-channel, current-limited power-distribution switch designed for applications where heavy capacitive loads and short circuits are encountered. It operates over a supply voltage range of 2.7V to 5.5V and provides a continuous output current of up to 0.5A. The device integrates a 70mΩ N-channel MOSFET switch with over-current, over-temperature, and reverse-current protection. The TPS2049DR is available in an 8-pin SOIC package and is characterized for operation from -40°C to +125°C.
