I'm looking for a circuit that functions similar to what a laptop would do: when it's plugged in, it charges the battery, and when unplugged it runs off of battery. You can plug/unplug at any given time without having to power down.
All of the LiPo charging circuits I've seen are just that, to charge a battery. How can I expand a circuit to also allow power to be supplied to a device while at the same time also charging the LiPo (if needed) and when power is removed, the LiPo takes over and keeps things running? And when power is re-applied, it recharges the LiPo while also supplying it to the device.
Thanks all!
