Other Parts Discussed in Thread: BQ29312A
Hello
I'm investigating an old project based on bq2084+bq29312A.
I have a pack with a sever cell imbalance > 2000mV, and I'm expecting to see the PF CIMB flag to be set but nothing.
I think all the settings are in place:
Cell Imbalance Threshold 0xEE-0xEF: 500mV
Balance IMAX 0xF2-0xF3: 10mA
Cell Imbalance Time 0x134: 20s
When the pack is charging (precharging because of the imbalanced cell is < 2000mV) with approx 20mA, the Max imbalance is not detected and the PF-CIMB flag is not set.
What other settings need to be set to activate the critical imbalance condition to be detected ?
Thanks
Pietro
