Hello! I want ask some additional questions which I could not find and get from datasheet.
First thing is it possible to use USB voltage level for input to charge 2 series connected Li ion cells?
Here in above picture is copy from datasheet page 3. It is one of typical configurations. If answer on first question is positive, how can I minimize the circuit, if it is known that charger input voltage will always be USB compatible, load will be connected only when charger is disconnected, I wont use any other AC inputs. Which transistors can I get rid of?
