Re: Laptop battery charging circuit
Hello,
I have a question to the following:
DCIN/VCC: input voltage from the AC adapter, should be close to AC adapter voltage
Does the input voltage always come from the AC Adapter? Is the charger IC inactive when running from battery? I was trying to understand the input voltage for Quanta FH5 mainboard, there seems to be no connection to the battery rail although in every IC charger datasheet you read about input from battery and in other schematics VCC is connected to the battery input.
