Hello everyone,
This question is a duplicate of this question: 
Because it has been marked as "TI thinks resolved" but it is definitely not resolved.
I just noticed that when setting the current to low value (<= 300 mA, which is not that low), the charge completely fails to deliver said current. We can observe big overshoot for a bit and then the security gets triggered and cut the charge.
For higher current (i.e 350mA), this problem doesn't occur, I get a current significantly lower than expected, as described in other posts.
So, how can I get lower currents? This particularly critical especially because the pre-charge isn't working.
I attach the configuration I used: "testLowCurrent.gg.csv" (I only put the last one I used with 350mA, only "Rec Temp Charging/Current Med" changes for the different tests) and several logs with different values set for the charging current: "testLowCurrentXXXmA.log"
And here some plot:
I also attach the configuration (.gg.csv) that as been used during those tests. The sensing resistor is 10mOhm, therefore the configuration of "Advanced Charge Algorithm -> Charger -> Current Resolution" set at 39 is right. I am worried that the resolution is not good enough to regulate small current, but we tried with a 20mOhm resistor and didn't observe any difference.
I hope to get more useful answer than last time.
Best regards,
Yann
