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