Working Principles

The TPS22976DPUT operates by controlling the flow of current between the input (IN) and output (OUT) pins. When the enable (EN) pin is activated, the PMIC allows current to pass through from the input to the output. Conversely, when the EN pin is deactivated, the current flow is interrupted, effectively disconnecting the load from the power source.
