TPS2047BD TI Power Switch | 16-SOIC | 2.7-5.5V, 0.5A

Product Overview

The TPS2047BD from Texas Instruments is a dual-channel, current-limited power-distribution switch designed for applications requiring precision power management. It operates over a wide input voltage range of 2.7V to 5.5V and provides up to 0.5A continuous current per channel. The device features a 70mΩ (typical) high-side N-channel MOSFET switch with independent enable control, making it ideal for USB ports, hot-swap supplies, and general-purpose power switching. The 16-SOIC package ensures compact design and efficient thermal dissipation.
