Other Parts Discussed in Thread: BQ24210, BQ24650
Hey,
So I want to design a Solar charging circuit for a battery pack with 10000mAh, for MPPT i use a SPV1040 from St Microelectronics and I need a chip that controls the charging of the battery pack. So i stumbled across the BQ24200. The only concern I have is, what happens when the charging current drops below the 25mA of Itaper during the charge? Since the solar panel is heavily current limited it could happen that the charge current drops below this value. Is going to be a fault issued? If yes then how to disable this fault?
My problem with this whole circuit is that I'm using such a big battery pack that no ordinary charge controller is suitable, because they have timer's that are always going to be issuing a fault, because the battery pack is not full. Is there a solution to this problem?
