Other Parts Discussed in Thread: PMP, BQ25895, , TL431
Hello,
As I am student engineer I work for a project with PMP 11536.
I spend a while to analyze the schematic and I understand the most part.
But there are still two questions that stay mystery for me.
1. GND and PGND are linked by a Net-Tie.
Why GND and PGND are not the same ground plane ?
2. in this part of the circuit :
I understand Input is PMID from BQ25895 and Output is USB VBUS to charge devices. But I do not understand how it works ...
Thank you
Best Regards,
Theo
