In my system if I power the charger from USB without a battery connected it will detect that is a max charge device regB == 0x96. However it leaves reg0 to be 0x40. That means the input current limit is 100mA and the ilim pin is enabled (ilim pin is grounded in my design). Also in this mode it charges the battery with 200mA no matter what I seem to try.
If I first connect the battery, then connect the charger, it correctly sets reg0 and it charges the battery at my fast-charge current limit of around 600mA.
Any ideas what's going wrong?
