BQ24210: LiPo charger

Dams

Part Number: BQ24210

Hello, 

I want to use the BQ24210 in my design but it always mentioned "Li-Ion" battery on the datasheet and in my application I use a LiPo battery, can you confirm me there is no problem ?
The ISET resitor is just to limit the current of the charge but is doesn't have a impact about the total capacity allowed for the battery ? For exemple, if I charge during 2 hours at 500mA, it works for a 1A battery ?

Thanks in advance for support.

    Hello Dams

    "I want to use the BQ24210 in my design but it always mentioned "Li-Ion" battery on the datasheet and in my application I use a LiPo battery, can you confirm me there is no problem ?" -- Bill J -- The charge profile for Li-Ion and LiPo are the same and same charger can be used.


    "The ISET resitor is just to limit the current of the charge but is doesn't have a impact about the total capacity allowed for the battery ?" -- Bill J - The ISET resistor will set Fast Charge or CC phase of charging.  This value will depend on the battery manufacture recommendation.  Common value is 0.5C, for 1Ah battery this would be 500mA charge current.  As the battery voltage reaches 4.2V charger will enter CV mode and the charge current will decrease to termination value ending charge.
