Part Number: BQ29200 Hi.
My goal here is to implement the IC in a circuit using 12V as it's charging voltage.
To my understanding of the datasheet, the IC itself does not draw any significant amount of current from whatever source.
Then, is it safe…
Part Number: BQ29200 Hi Team,
I have got some questions for BQ29200 that need your help.
1. I see the OVP is 4.35v, what will BQ29200 do if the voltage exceed 4.35v?
2. The range of cell balancing 7.6V - 8.4V, what will happen if the max voltage is…
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…
Hello,
The OUT pin is just for over voltage fault detection.
Also, charge current is not what determines the balancing current. The balancing current is determined by the cell voltage. This should allow for cell balancing while charging.
BQ29200 and BQ29209…
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…
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 +…
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…
