Selecting a chip

Other Parts Discussed in Thread: BQ24160

I am seeking a battery charger chip. there will be 2 inputs. Solar charging and 5V-12V DC charging. I need a chip to auto detect and select. It needs to charge a battery. also it needs to have a Vout to power the system Via battery or DC voltage. any reference designs will be helpful. 

  • Hello,

    The challenge of answering your question is that you do not give the following information:
    Battery Chemistry
    Battery configuration (How many cells in series)
    Charging Current

    The other challenge is that Solar sources can be a challenge to work with since the operate on voltage and current curve that is influenced strongly by how much light they are collecting.

    If you can lower your peak input voltage and you can precondition your solar source and this is only a 1S battery I would recommend looking at the bq24160 family seeing as is support two inputs.
