Working Principles

The TPS2064DGNG4 operates as a power distribution switch by controlling the flow of current between the input and output terminals. When the enable input (EN) is activated, the switch turns on, allowing current to pass from the input (IN) to the output (OUT). The integrated protection features monitor the current, voltage, and temperature levels to ensure safe operation. If any of these parameters exceed the predefined thresholds, the switch is turned off, protecting the system from potential damage.
