Does the bq24640 also support Li-Ion Battery?
If the bq24640 also supports Li-Ion Battery, how to detect the Termination?

    Hi Kagawa-san,

       What is the need to use BQ24640 for charging Li-ion battery? This is a charger intended for supercap, and does not have a precharge range. This is dangerous for Li-ion chemistry as Li-ion discharged batteries should be charged at low currents. For Li-ion you can look at BQ24600 which is from the same family of chargers, or BQ24610 (recommended) as it has a couple of more extra desired features (IINDPM, Direct Powerpath)
