Hi Hong,
Do you have some updates on this?
Actually, PVIN pin and VPIN are connected diffrent voltage rail because of battery system sometime.
So let me make sure this issue again.
The applied voltage on PVIN pin should be higher than on VIN pin, right?
I think VINpin is supply voltage for ADP2164's logic circuit, not power cirtuict.
In general, the voltage shold be applied VIN pin first for the sequence control, I believe.
Do you mind giveing your opinion on that?
Best regards,
Tarzan
