Hi team, 

Why does he has divider3 instead of divider1 and divider2?

I found that TPS2549-Q1 and TPS2546-Q1 looks similar function but different DCP auto operation such as "Divider3 mode" for TPS2549-Q1 and "Divider1 mode and Divider2 mode" for TPS2546-Q1.
Do each divider mode has each targer load device such as iPhone?

Regards,
Ochi

    Hi, Ochi,

    TPS2549-Q1 integrated apple new released divider 3 mode which support higher charging current of 2.4A. Divider1 and Divider2 are old charging protocol which support max 2A charging current. Now the Divider 3 is more popular and compliant to most of apple portable devices.
