Hello,

Will make charger board as attached.

Could you check if there is any miss or need to modify?

Regards,

    Hey Nicky,

    Just a few things after looking at your schematic:

    1) C14 - We typically recommend around 20uF minimum on the PMID pin. Right now you have 4.7uF.

    2) I assume PVDD_LDO2 is somewhere offscreen and is being powered appropriately by something external to this schematic provided.

    3) Note the ILIM current is worst case. DPDM detection will most likely set your ILIM current value (in memory) to a lower value.

    4) Could you explain the pullup resistors on D+/D- pins (R276, R277)? We typically do not recommend pull-ups on these lines if detection will be used. This may affect the USB detection.

    5) I cannot speak to the MAXIM part system connection as this TI moderated forum, so just clarify with them to ensure proper design.


    Other than that, I can't identify any other possible concerns.


    Hope this helps!

    Regards,
    Joel H
