we are trying to communicate with the ADP over an I²C/SPI Bridge (SC18IS600, NXP). In my opinion it should work fine. Without activating the PFC/Boost function (PSON OFF) the communication works fine. If i activate the PFC (without any load) all the data are corrupted. The SC can´t Interface the ADP. The signals are looking very good. So there cant be a Problem. Does anyone have both ICs working together and can give a hint what i have to look for?
Maybe the Problem isnt new for someone? Maybe someone can Name a proven Bridge which works fine with the ADP?
