Other Parts Discussed in Thread: BQ34Z100 , BQ29200 Hello
We have a design using the BQ34Z100 and a BQ29200 overvoltage protector with in built cell balancing.
The cells are arranged as 2 in series.
As I understand it the balancing circuit shunts…
Other Parts Discussed in Thread: BQ29200 Hi, I am looking at page 5 of the data sheet for the bq29200 voltage protection and cell balancer and I see the equations for the cell balancing current (ICB1 and ICB2) but cannot figure out where in the table…
Other Parts Discussed in Thread: BQ29200 Hi,
I've got a 2S LiPo with 3600mAh and a Controller-based charger (CCCV) which delivers 1300mA charge current. My Problem is the dimensions of the Resistors and the Capacitors in the circuit. Does the 15mA balancing…
Other Parts Discussed in Thread: BQ29200 , BQ20Z45 , BQ28400 , BQ29412 , BQ20Z40 , STRIKE , MSP430F5659 Hi,
I am planning to use BQ29200 mainly as a cell balancing chip for a BMS of 2-series Li cells. I am using another IC (Maxim's DS2777) as the battery…
Other Parts Discussed in Thread: BQ34Z100 I already know that our VC1 and VC2 are connected to the wrong cells, so, please ignore that part of the design. It doesn’t have any effect on my question. Please see attached schematic.
What if the enter balance…
My customer asks:
I am designing the PCB with the part and data sheet is a bit confusing: in section describing mechanical package dimensions, two drawings are shown: one with thermal pad (datasheet page 12) and other without (datasheet page 13). Later…

Other Parts Discussed in Thread: BQ29200 I am looking at the BQ29200 dual cell balancing device from TI. Do you have any white papers, design guidelines, application note, or amy other collateral which show an example charging circuit? I checked device…
Part Number: BQ29209 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…
Part Number: BQ29706
Hello,
I want to use BQ29706 and BQ29200 for 2S1P configuration of lithium iron phosphate (LFP) battery. I have few questions regarding this:
Q1: As a LFP has upper voltage limit of 3.65V, can I use BQ29706 (OVP=3.85v) for cell…
