Hi Prathamesh,
1. The charge current for the battery does not control balance current for the BQ29200. The balance current will flow in the cells and BQ29200 circuit. The easiest way to observe balance current may be the voltage of the VC1_CB pin or…
Part Number: BQ29200 Hello, we used the BQ29200 in a 'quick fix' product that allows us to move away from prismatic to AAA cell's. Looking at the schematic that was done, I noticed an error. Our schematic has a Cin connected between pins 1 and 2 which…

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…
Hi Dan, The bq29200 data sheet does not include characteristic curves for the VMM_DET_ON and VMM_DET_OFF over voltage. Since the calibration point is at 7.6V one might expect the accuracy is not as good moving away from the calibration point. The section…
Part Number: BQ29200 Other Parts Discussed in Thread: BQ2970 , BQ4050 , BQ40Z50-R1 , BQ28Z610 Hi,
Can i connect BQ29200 as my schematic ?
Does it work during the charge of the batteries and also during the discharge ?
Can i have it always enable…
Part Number: BQ29200 Hi team,
Could you please help have a look at the schematic provided by customer?
And if there is other attention need be paid for customer?
Thanks.
Part Number: BQ29200 Hi,
I have a question about BQ29200 cell balancing. Could you please explain how does the cell balance circuit work?
The block diagram in the datasheet shows it will short VC1_CB to GND or VDD.
So I think the cell balancing…
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…
Hi MJ,
If the batteries are cells with protection for the pair, BQ29200 family can provide balancing. If the batteries have internal protection it is not a good idea since the part can draw extra current if the bottom cell is not connected first. OUT…
Part Number: BQ29200 Other Parts Discussed in Thread: BQ2980 , BQ2970 Hi Everyone,
I'm looking at using the chip for cell balancing and second level protection. I'm slightly confused about what is being denoted by the fuse and FET circuit connected…
