Part Number: BQ29200 Hello, we are prototyping some battery management circuits that use a combination of an over/under voltage protection IC with the BQ29200 for cell balancing on a 2S 18650 LIPO pack. We are effectively using the circuit in figure 11…
Part Number: BQ29200 I'm looking for a low cost solution to balance over 100 series Li Ion cells. I would like to use the BQ29200 in the following configuration:
C4
}BQ
C3
BQ{
C2
}BQ
C1
I don't need OVP, just balancing. Since I have to repeat…
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,…
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…
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…
Other Parts Discussed in Thread: BQ29200 Hi
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…
