Hello Vignesh,

Can you clarify the issue, I don't understand what the issue is?

Are you saying the STAT and PG signals are not showing the correct status?

If this is the case, can you use the adapter as the pull up rail and use a 10k resistor instead of a 100k?

Best Regards,

Christian.

Hello Vignesh,

Yes, on R77 and R76 you are using a 100kohm pull up to the 3v3 rail. Can you switch both of these to a 10kohm and use the adapter as the pull up rail.

Best Regards,

Christian.
