Device Functional Modes

The device has two functional modes of operation controlled by EN. When there is a logic high on EN, the device is in the normal mode of operation and the power switch is on. When EN is logic low, the device is in a low-power mode where the power switch is off and the supply current is reduced to less than 1-μA.
