Hi all; sorry for being so vague but I'm not sure where to begin.
I have a embedded computer that I want to use an internal battery. I need the computer to run off the battery unless it is plugged into an external power source, then I need it to charge the battery to capacity and power itself off the external source. When I unplug the power source, I should use the battery without shutting down. IE: smooth source transition both directions. I already have the appropriate hardware to handle different voltage inputs, so no regulation is needed - just the transition and charging.
This seems really obvious but I'm not sure where to begin. It seems that part of the circuit is a charge controller but that's only a piece of it. Tons of portable devices do this but I can't find the appropriate name to know where to search. Ideally it would support lipo batteries, but I'd be happy with SLA if necessary.
Thanks much!
