Hi Davide,

The issue in the thread was due to customer down system

Can I know exactly what is the issue you are facing?
Best Regards,

Hi Sailendra,

the issue is that if there is 1.5V on the output of the switch when it's open, it won't close. I can't find anything related to this behaviour in the datasheet. Our workaround was to delay other power lines in order to prevent this condition, but this is not optimal.

No, I'm not allowed to share the entire schematic. I can share part of it if you explain what are you looking for.
