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?
Part Number: BQ29209 Hi guys,
on the data sheet of the component I see an internal pull up connected on CB_EN pin and I not connect an external pull up but when VIN is disconnected the CB_EN pin increase only at 0,6 V. What is the value of this pull …
Part Number: BQ29209 Hi guys,
my application is 2S Li_ion battery 3,7V 700mA with charging current CC/CV at 100 mA.( 8 h for complete charge).
In my previous test the imbalance voltage (without BQ29209) is around 250/300mV at the end of charge.
The draw…
Part Number: BQ29209 I use this part to balance a 2S battery. After a very long time (several hundred total charge cycles of the battery) there have been 2 units that have failed.
I noticed that the battery became very unbalanced, and when I probed RCB…
Part Number: BQ29209 Other Parts Discussed in Thread: TINA-TI Hi, the recommended schematics for external cell balancing might not work like it's intended. In case of Q1, the Drain Source voltage will be the same as the Gate Source voltage when activated…
Part Number: BQ29209-Q1 Hi Team,
Good day! I am posting this in behalf of the customer. Kindly confirm if Q29209-Q1 still works fine if customer used only one cell instead of two. The datasheet shows the configuration for the 2-series cell battery connection…
