Basic high voltage load switches consist of four pins for input voltage, output voltage, enabler, and ground (earthing). When the device is enabled via the ON pin, the pass FET (field effect transistor) switches on, thereby allowing current to flow from the input pin to the output pin. Power is thus passed to the downstream circuitry.
