Hey guys
Anyone have any recommendations for a charging circuit with UPS for a 2 Cell LiPo pack connected to an Arduino Ethernet?

mrjonny2

I need one that will act as a UPS at the same time, kinda like the one in the Fio, as I cannot have my arduino reset

the other thing i am looking to use a large 2 cell LiPo pack as well

hey guys sorry,
not the packs themselves but the charge circuit.  would be the cheapest method be to use a system on chip design (recommendations?)  or a circuit?

That isn't really what I am looking for,
I was looking for more of a circuit I could integrate or build myself in order to keep costs as low as possible

See data sheet at http://ww1.microchip.com/downloads/en/DeviceDoc/22190b.pdf. It the suggested circuit diagram in it.


Look at page 2 of this datasheet for an example circuit. Its very simple. At $1.94 plus two capacitors and one resistor I don't think you can complain about the cost. You won't find much cheaper elsewhere. (Sheeeesh!! You can lead a horse to water but you can't make it drink!)
