Part Number:BQ25708
Dear support,
in the datasheet is metioned, that a deeply discharged battery is charged in precharge-mode.
What is the function of "VVBAT_UVLO"? Does the charger tries to charge a battery, if the VBAT is below VVBAT_UVLO?
(see 8.3.1 in datasheet)
In the datasheet (see 8.4.1.2) is a sentence "When battery is full or battery is not in good condition to charge, host terminates charge by setting
REG0x12[0] to 1, or setting ChargeCurrent() to zero"
What is the meaning of "in no good condition to charge"? Is this related to the Vvbat_uvlo?
Does the charger tries to charge the battery, even when it is "in no good condition to charge"?
We have tried to charge a battery with 2.0V (Charger programmed to 3S) and the charger does not enter precharge mode.
Regards,
Volker Placke
