TPS1H100-Q1: The NC pin issue

Part Number: TPS1H100-Q1

Tool/software:

Hi,

We have chose TPS1H100-Q1 for our highside driver, and now, we need to connect the PIN1 to GND but the PIN1 is NC and neet to leave floating in the datasheet,

we can't search the internal design for the PIN1 so we have no idea that it has any risk for our design;

Please help to confirm if we can connect the PIN1 to GND, thanks.
