UCD90320: on dependencies logic

Hi team,

Cisco is using our UCD90320 in their design.

Regarding on dependencies, these conditions must be met before the device will be powered on, right?

If they are met, and after normal power-on, if one of the GPIOs is not met, will the device automatically power off?

No, device won't turn off if the dependencies are changed.

Hi Yihe,

So after rail power on, if the on depends changed, the rail still power on, right?

and the power off status just depend on the "off depends", right?

Once rail is on, on dependencies change won't impact it.

off dependencies won't trigger a off since it is a conditions only.

Please refer this guide to understand more
