Working Principles

The TPS2818MDBVREPG4 operates as a high-side switch driver by receiving a control signal at the IN pin. When the control signal is high, the device turns on the high-side switch, allowing current flow between the OUT and GND pins. Conversely, when the control signal is low, the device turns off the high-side switch, interrupting the current path.
