The EN pin controls the state of the switch. The EN pin is compatible with standard GPIO logic threshold so the device is useable in a wide variety of applications. When power is first applied to VIN, a Smart Pulldown is used to keep the EN pin from floating until the system sequencing is complete. After the EN pin is deliberately driven high (≥ VIH), the Smart Pulldown is disconnected to prevent unnecessary power loss. See the below table when the EN Pin Smart Pulldown is active.
