Other Parts Discussed in Thread: BQ24210, BQ24650

Hi,

Can anyone please suggest me a Li-Ion battery charger that is required to charge the Li-Ion battery 3.7v, 4400 mAh and the portable device of 3.3v, 500mA. The solar panel used is 9v, 660mA.

Which one BQ24210 or BQ24650 is best for my application??

Thanks in advance!

Depends on the charge current requirement. The OVP on bq24210 might not allow you to use this panel. You can also see the following application note for the bq2425x for solar panels.
