Can someone please confirm if PCAL6524 QFN32 package's center exposed pad can/should be connected to ground?

Thanks!

Hi Paul,

The exposed pad underneath the PCAL6524HE (HUQFN32) is not internally connected to any pin. It can be left floating, but for better thermal performance it is recommended to connect it to the GND.

The exposed pad outline and the recommended footprint can be found at:
