Other Parts Discussed in Thread: BQ34Z100, BQ25703A, BQSTUDIO
Hi again TI,
I am struggling with the BQ34z100. I've got no certain Qmax value, so followed the steps on SLUA334b, for no close Qmax known. I decharged with a charge terminal which is capable to decharge.
After that I went to charging with the BQ25703A EVM board. When the current dropped under 100mA I expected the FC bit to set. However, after 3 times waiting the taper window of 40 sec, still nothing happend. I didn't dare to leave it sort of charging through the night, so disconnected it and ask for help. Tonight it won't be charging, but I will keep logging.
Attached hopefully enough info with log and data memory export file.
edit next day:
In the datasheet I found:
Full charge is detected. FC is set when charge termination is reached and FC Set% = –1 (see Charging and Charge Termination Indication for details) or StateOfCharge() is larger than FC Set% and FC Set% is not –1. ALERT is enabled when set.
There is probably my problem. State of Charge didn't change at all and FC Set % is at 100. Why didn't those change?
