What's the voltage headroom required from the adapter voltage to the battery charge voltage (8.4V in my 2 x Li Ion case)? I didn't see it in the datasheet. I'll be using wireless power source for charging, so it's important to know the minimum "adapter" voltage needed. Thanks.
Side note - it looks like TI does not make a 15W Qi power receiver that outputs 9V or more. Is this correct, or did my search miss something?
