Hi;
We have a new design with BQ24735RGRR. Now we can communicate with IC. The IC sends ACK at SMBUS but the charge function doesnt start. We try 1s,2s and another combinations. Charge starts only 1s but charge current is very low( only 40mA). The charger output does not exceed 5.8V. I attached the schematic and Register config. We tried all register combinations and search about document which about all. I deactiveted ILIM pin. Now it connected via pull up(3v3) via 10K resistor. I also use logic analyzer at SMBUS too. All the data is correct. We did'nt solve why does'nt charge start and How we change 1S,2S ...etc
ChargeOption() -> 0b 0001/1011/001x/1x00 x-> read only bit
ChargeCurrent() -> 0b xxx1/0000/00xx/xxxx x-> not used
ChargeVoltage() -> 0b x010/0000/0000/xxxx x-> not used
InputCurrent() -> 0b xxx1/0000/0xxx/xxxx x-> not used
