Part Number: BQ29209 Other Parts Discussed in Thread: BQ25300 , BQ25306 , Hi everyone. I need some advice because I'm not very skilled about battery management
I have two single cells (each with PCM). I have two possible technologies: either LiPo cells…
Part Number: BQ29209 Other Parts Discussed in Thread: BQ77307 Hello,
i'm using the BQ29209 with LiFePo4 (2S) cells and would like to know if it's possible to limit the threshold for Vprotect to 3.8V,
or do you have an alternative suggestion?

Part Number: BQ29209-Q1 Hi
The customer design with BQ29209-Q1. BQ29209-Q1 is used to design the balancing circuit of two series cells. After the battery pack is welded and the electrical performance test is completed, it is placed in inventory for 2 months…
Hello Stefano,
The internal pull-up is a high-impedance current source, it would not work well as a pull-up. I mentioned to use an external pull-up resistor in our previous e2e thread: https://e2e.ti.com/support/power-management-group/power-management…
Part Number: BQ29209 Hi guys,
In my application I have CB_EN in low continuous condition and during charging the balancer mosfets are controlled properly. If the battery voltages are more different, the balancer is unable to perform balancing and one…
Part Number: BQ29209 Hi Guys,
I'm cheking my application with BQ29209 about overvolage protecion condition.
During charge the OUT pin go high at 4295 mV but when the Vbad decrease of 20/30mV the OUT pin go low; in the data sheet is showed an hysteresis…
Part Number: BQ29209
Hi guys,
in my application i need reduce the number of wire that connect the balanced circuit with charger circuit composed by step up and linear battery charger. The overvoltage must disable the step up and the balancing must b…
Part Number: BQ29209 Hi, guys:
I tried to use bq29209 to build a battery management system but I did not find the model in pspice for TI and online, how can I get the model to simulate?
Part Number: BQ29209 Hi guys,
I am testing the device.
If the voltage imbalance is high (4.0 and 3.6) is not able to balance the different voltage.
If I increase the current drain capability (witouht external mos) can I improve the performance ?
What…
Part Number: BQ29209-Q1 Hello,I have issue: when I measure voltage between VC1 and VC1_CB, sometimes voltage occurs 1.4V, sometime is 0V, battery are balanced. Any ideas?
