Exposed Pad in QFN

We plan on using the W6100-Q, which has an exposed pad. I could not find any hint on the electrical connections of this pad in the datasheet.

i. Can this pad be connected to GND (or GNDA)?
ii. Must this pad be connected to GND (or GNDA)?
iii. Must this pad be equipped with vias in order to increase heat transfer to the bottom layer?

Kind regards,

Paul

Hello, Sorry for late response.
I told hardware engineer about your question.
He will response about it.

Dear p.wagner.

Is the pad you’re talking about in the middle of the QFN?

if so,

We recommend connecting the pad to GND. And recommended to add via. But not must.

Normally connect GND and add vias.

Thank you
