Hi Sir,

Could we support the I-phone charging by TPS25810, is there any specific mode that we need to set for the I-phone?

Others Android phone can be charged properly when system into S5, please help to advise if there is any specific set-up that we can let 25810 support I-phone.

BTW, please refer to their block diagram as below application schematic.

Thanks,

George

    Hi George,

    If the phone cannot negotiate over the CC lines, it will default to negotiating BC1.2 charging over the Dp/Dm lines. The TPS25810 does not support BC1.2 charging because it does not interact with the Dp/Dm lines. 

    Do you have a Dp/Dm controller, as shown in the example below? 

    Thanks,

    Emma
