Hm, I’m afraid that won’t work.

Can you use this ‘online’ – i.e. keep a constant 5v supply either from the incoming power or the battery? I’ve just bought an energy monitor that uses a usb connector for power and realised it has no option for batteries internally which is a shame for carrying it about so I was thinkling something that could act as a backup would be great

usb connector seems like an afterthought, if you intend to use usb check out another IC like

with current limiting

Alex, Thanks for the info on the MCP73833 – I had been looking for a simple LiPo charger for a while now. Maxim has neat parts but their availability sucks!

No need for another jack, you can use a AC-to-USB power supply, like this one:

You can connect a 5V power supply to it if you don’t want to use your USB. That one is to be replaced with a proper jack in the next design.

Sorry, didn’t look properly, that one must be just a battery connector. But what is JP2 used for?
