Hi Michael,

Based on the block diagram, it looks like VDD can be left floating if the I2C isn't needed. I will confirm this in the lab tomorrow and let you know the results.

Thanks,

Hi Michael,

I tested this in the lab today and found that the load switch functioned properly (with GPIO control) when VDD was left floating.

Thanks,
