Hi,
I would appreciate if someone would be able to comment/advice on the following matter. I have been looking around for an IC that would charge and balance Li-Ion cells 2-3 of them in series. It seems that the balance feature is absent in most cases. MCP73841 appears to provide most of the feature need to safely charge 2 x Li-Ion cells, can this IC charge/manage cells rated at 6.4 – 3000mAh (2 x 3.2 - 3000mAh). The datasheet states “For the 500 mAh battery pack example, a standard value 220 m, 1% resistor provides a typical fast charge current of 500 mA and maximum fast charge current of 551 mA. Worst-case power dissipation in the sense resistor is:” Therefore, this leads me to believe that this is not a suitable solution for my setup. Please correct me if am wrong and if so, would you be able to advise an alternative IC?
