Other Parts Discussed in Thread: , BQ25882
Hi,
first of all, I'm sorry for my poor experience about battery management circuits.
I have to put in series two Li-ion batteries (3,7 to 4,2) in order to get more voltage from them. I focused on the BQ29209-Q1 but I have some doubts about it I hope you can clarify:
- Is the Bq29209 also a battery charger or just a device which takes care of unbalancing issues ? If not , is any battery charger suitable?
- From the datasheet I see that there is an external network to do if the automatic confguration cant make its job. How can I Know if I have to design the external network or keep the automatic configuration ?
- From the datasheet , the recommended VDD is 10V. Can I use 12Volt coming from another big battery on its input? If not could you suggest an LDO in order to get 10V on output (current rating) ?
Hope you can help.
Thanks in advance for your support.
Nico
