Hi community,


Our partner have some question about MMPF0100 connection when unused.

Please see Table 1 of AN4717 (Schematic Guidelines for the MMPF0100).



The recommended connection when not used for the following pins are "Leave floating".






We want to confirm the meaning of "Leave floating".

I understand "Leave floating" means "No Connect", so all circuits and materials written in "Recommended connection" column (e.g. capacitor, shottky diode for SWBSATLS) are NOT required.

Is this correct?



Please see the "Recommended connection when not used" for VINx.

These are written as "Connect to regulator with output voltage < 3.*V", or "Connect to VIN".

I understood these power supplies are required even if all VGEN outputs are unused, we cannot be these pins as "Leave floating".

Is this correct?



Best Regards,
