Other Parts Discussed in Thread: BQ24650, BQ29200
Tool/software:
I'm considering using the BQ29209 in my 2 cell lifepo4 charger circuit. However, I would like the charging to stop while the cell is being balanced to avoid overloading (in case of constant current) the balancing resistors. I could do this by switching the same MOSFETS that are used by the under/overvoltage protection IC with the help of the BQ29209 OUT pin.
The datasheet states that the OUT pin will go HIGH when overvoltage is detected at one of the cells. Will the OUT pin also go HIGH when there is imbalance (>30mV) between the cells?
