Part Number: BQ29200 Hi.
I have a 2 cell lithium battery application.
I charge with MCP73842-8.4 from 12V (AC ADAPTER) , the batteries go to dc-dc converter.
I woul like to use BQ29200.
The question are ?
Can i have the Cell balancing always enabled,…
Hi Mehmet,
I am covering the monitor and protector portfolio and unfortunately we do not have a monitor that can work with your 2s application.
The only offering that appears to fit best here is our BQ29200 & BQ29209 2s protector with cell balancing feature…
Part Number: BQ29200 Other Parts Discussed in Thread: BQ77905 , BQ28Z610 Hi ,could you help give some suggestions how to use BQ29200 design for Overcharge Detection (OVP)、Over-Discharge Detection (UVP)、Load Short-Circuit Detection (SCP);from the datesheet…
In the datasheet in Section 9.3.1, "External Cell Balancing", there is an expression Ibal=Vcell/Rcb_ext.
How does this expression may be true, if the external transistors (figure 11) can not be completely open, and the drain-source voltage is…

I'm confused about figure 9 in the datasheet of BQ29200 "2-series cell configuration".
On this picture, the current even flows through the 100-ohm-resistor and then through the fuse to "Pack +…
Other Parts Discussed in Thread: BQ29200 Hello,
According to Figure 9. 2-Series Cell Configuration in the BQ29200 datasheet, Rvd is connected in series with the cell and pack +ve.
This would mean at least 100 Ohms in series with the cells, dramatically…
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 the cell…
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 above…
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…
