First of all thanks in advance for your reading and help.
I've seen from LT3652 datasheet that VIN must be VBAT(FLT) + 3.3V in order to startup correctly. What does that mean practically ?
Let me explain why I am confused :
I have a LT3652 to regulate a small voltage solar panel (it has its maximum power point at around 6V and can climb up to 9V when fully illuminated). It would charge a 1S2P Li-Ion battery pack (4.2V VBAT(FLT)).
I don't know at this point what will happen when, in the morning, the sun will rise and the solar panel voltage will be under the condition of (VBAT(FLT) + 3.3) (7.5V).
During a sunny day the condition will be fulfilled: VIN will be >7.5V because there will be no load on it (it could even go to 9V). Then, I expect the LT3652 to start charging and start regulating, so that VIN never goes under 6V. Is that possible ?
My question is : how will the LT3652 react during the time where VIN < 7.5V ? It's not mentioned and I am wondering if there could be any issue preventing my circuit to start charging correctly.
Again, thanks a lot for the help.
