Working Principles

The TPS2065DGNG4 operates as a power distribution switch by controlling the flow of current between the input and output pins. When the enable pin (EN) is activated, the power switch turns on, allowing current to flow from the input pin (IN) to the output pin (OUT). In case of an overcurrent condition, the built-in protection mechanism triggers, disabling the power switch and signaling the fault through the FLT pin.
