7.4.1 Enable and Disable (EN)

The device is enabled by setting the EN pin to a logic High. Accordingly, shutdown mode is forced if the EN pin is pulled Low with a shutdown current of typically 1.5 μA.

An internal 400-kΩ pulldown resistor is connected to the EN pin when the EN pin is Low. The pulldown resistor is disconnected when the EN pin is High.
