Working Principles

The TPS2111PWR operates by continuously monitoring the voltage levels of the two input sources (IN1 and IN2). It automatically selects the higher voltage source and connects it to the output pin (OUT) while disconnecting the lower voltage source. This ensures that the device being powered receives the highest available voltage.

Additionally, the TPS2111PWR incorporates protection mechanisms such as overcurrent detection and reverse voltage protection. If an overcurrent condition is detected, the device limits the current flow to prevent damage. In case of a reverse voltage, the device blocks the flow of current to protect itself and the connected components.
