The logic enable pin controls the power switch and device supply current. The supply current is reduced to less than 1 μA when a logic low is present on EN. The EN pin provides a convenient way to turn on or turn off the device while it is powered. When this pin is pulled high, the device is turned on or enabled. When the device is disabled (EN pulled low), the internal FETs tied to IN are disconnected, all open drain outputs are left open (Hi-Z), and the CC1/CC2 monitor block is turned off. The EN pin should not be left floating.
