Working Principles

The TPS2115PWG4 operates by continuously monitoring the power sources connected to its inputs (IN1 and IN2). It selects the appropriate power source based on the enable pin (EN) status and automatically switches between them. The power good (PG) pin provides an indication of the selected power source, while the fault (FLT) pin alerts the system in case of any issues such as overcurrent conditions. The device also incorporates overcurrent and thermal shutdown protection mechanisms to ensure safe operation.
