Part Number: BQ29200
I'm in the process of implementing cell balancing functionality for a 2S1P 18650 Li-Ion battery pack and looking to use the BQ29200 in tandem with a charger that provides OV, UV, Thermal, etc... protections.
The BQ29200 expects…
Part Number: BQ29200 Other Parts Discussed in Thread: BQ77915 , Hi,
Is it possbile to use 2xBQ29200 to balance 3 cell in series?? In such a case on of them would not be referenced to ground but to the voltage of one the cells.
Part Number: BQ29200 Other Parts Discussed in Thread: BQ29209 , Hi,
When making a Portable Audio product, I intend to use two 1cell batteries connected in series. Is there any problem using the BQ29200 or BQ29209 as the balance IC of the two batteries? …
Part Number: BQ29200 Hello, we are experiencing a lot of 'swollen' batteries from the field lately due to field personnel using the wrong adapter supplying VDD. When this occurs, the 29200 allows VDD across one battery (2 18650 in series) which obviously…
