Hello Katrina,
Having pack+ as the common node is exactly how our EVMs are designed. Pls refer to the user guide of the particular device in question for the reference schematic.
thanks

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: 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…
Oh, I was just thinking to leave the overvoltage bit disconnected entirely - something like this perhaps?
Although it wouldn't hurt to have both overvoltage protection chips there I suppose. I can't eliminate the second one however, as I need…
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…

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 protection…
Hi Dan,
I'm glad you like the BQ2980! As for your questions:
Yes I would suggest the BQ77915 for this application. You are correct, it will see the the parallel cells as one single cell. This is also true for the rest of our devices.
For 2S, your…
Hi Konstantinos,
Can you provide the battery part number? I would like to understand it better. Based on your explanation, it appears that your suggestion would work as the external battery FET is only for discharge and the SRN pin is used to sense…
Part Number: BQ25892 Other Parts Discussed in Thread: BQ25882 , BQ29200 As I already asked at title.
Do I have to worry about cell balancing for cheap hobby-xxxing batteries?
What pros do for those?
let me know
B.
Regards.
