Working Principles

The TPS2114PW is designed to efficiently manage and distribute power from two different input sources to a single output. It automatically selects the appropriate input source based on the voltage levels applied to the IN1 and IN2 pins. The device ensures a seamless transition between the inputs, minimizing any disruption in the output voltage.

In case of overvoltage or undervoltage conditions, the TPS2114PW provides protection by disabling the faulty input and switching to the other input source. It also incorporates thermal shutdown protection to prevent damage due to excessive heat.

The power good (PG) pin provides an indication of the output voltage status, allowing external monitoring of the power supply. Additionally, the fault (FLT) pin signals any abnormal conditions, such as overcurrent or short circuit events.
