Working Principles

The TPS22958NDGNR operates by controlling the flow of power from the input to the output based on the enable signal. When the enable signal is high, the device allows power to flow from the input to the output. Conversely, when the enable signal is low, the device cuts off the power flow, effectively disconnecting the load from the power source.
