Hello Shwetha,

We have limited bandwidth, I recommend reviewing the schematic checklist for this device:BQ2570X_BQ2571X_BQ2572X_BQ2573X_SchematicChecklist (6).pdf and we will provide feedback if you have any questions.

Best Regards,

Christian.

Dear Christain,

Thank you for your response. We have followed the checklist you provided. Could you please review the schematic and provide layout((specifically the UPS section on page 3) feedback as soon as possible?

We have been following up with the FAE for the past three weeks without receiving a response. Your prompt review and feedback on the layout and schematic would be greatly appreciated, enabling us to proceed with PCB fabrication.

Thanks & Regards
