Working Principles

The TPS2114APW operates by monitoring the voltage levels of the two input sources (IN1 and IN2). It automatically selects the higher voltage source as the active input and connects it to the output (VOUT). When one of the inputs is turned off, the IC blocks reverse current flow, preventing any backfeeding between the sources.
