TPS2047DR TI Power Switch | 16-SOIC | 0.7A, 2.7-5.5V

Product Overview

The TPS2047DR from Texas Instruments is a dual-channel, current-limited power-distribution switch designed for applications requiring precision current limiting and thermal protection. Housed in a compact 16-pin SOIC package, this device provides independent enable control for each channel, making it ideal for power management in USB hubs, notebooks, and other hot-swap applications. With a continuous current rating of 0.7A per channel and an operating voltage range of 2.7V to 5.5V, the TPS2047DR ensures reliable power distribution while protecting against overcurrent and overtemperature conditions.
