Hi team,

I find below E2E thread for NC pin, can customer connect these NC pins to VDD directly? Thanks.

    Hi Jayden,

    The NC connect pin should either be left open or connected to GND. It should not be connected to VDD because this device is not rated for any kind of isolation and connecting these pins to VDD could cause leakage through the leadframe into the device--permanent damage on the device is plausible.

    Best regards,
