Overview
The TPS2110PWR, produced by Texas Instruments, is a 2.8-V to 5.5-V, 120-mΩ, 0.75-A power multiplexer. This device is part of the TPS211x family, which enables seamless transition between two power supplies, such as a battery and a wall adapter, each operating within the 2.8–5.5 V range and delivering up to 1 A. The TPS2110PWR includes extensive protection circuitry, including user-programmable current limiting, thermal protection, inrush current control, seamless supply transition, cross-conduction blocking, and reverse-conduction blocking. These features simplify the design of power multiplexer applications significantly.
