TPS2112PW TI Power Management IC | 8-TSSOP | 2.8V-5.5V, 1A

Product Overview

The TPS2112PW from Texas Instruments is a dual-input, single-output power multiplexer designed for seamless power source selection. It operates over a wide input voltage range of 2.8V to 5.5V and supports continuous load currents up to 1A. Housed in a compact 8-TSSOP package, this device ensures low on-resistance (typical 120mΩ) and minimal quiescent current (typical 55µA). The TPS2112PW automatically switches between two power sources (e.g., main battery and backup) based on priority or voltage level, making it ideal for systems requiring uninterrupted power.
