Hey Reza,
We need a register dump the moment before and the moment after the charger stops charging.
A waveform is also necessary, showing VBUS, IBUS, SW2, and VSRN.

Dear Joel
hi, thanks for reply
unfortunately i am not able to check waveform and share with you but i have found out that when i write some values to charge current register BQ doesn't charge batteries but for some other values it starts charging but also in this way charging current is not same as i wrote it.
which registers do you want to know before and after. just let me know
thanks again
best regards
Hey reza,
I would like to see all charger registers before an after.

Hi!
Check the watchdog timer in ChargeOption0 register (I2C address = 01/00h) - WDTMR_ADJ.
The default setting stops charging after 175s without repeatedly sending the charge current.
You can disable the watchdog by setting 00 for bits 6-5 - then the charging will not stop when you don't send the current register.
Best,
P
