Hey guys,

I'm messing around on a project that uses Li-Ion batteries as the main circuit source and I'm trying to find an IC that can monitor the battery capacity and maybe provide some over/under voltage and short circuit protection (these last couple options would just be icing on the cake if it came in a fully integrated package). I'm hoping to use an IC that doesn't need to incorporate any kind of micro in the circuit design (it's a mixed signal design that doesn't include any microcontroller), so I'm looking for something that doesn't have any kind of I2C, SPI, or other interface. Just simple hi/lo output signals when the IC detects a low battery capacity...
My design will incorporate two 3V 225mAh coin cell (CR2032) Li-Ion batteries connected in parallel. The circuit draws roughly 80mA max and 25mA nominal.
I'd prefer an IC that's some kind of SOP or SOT package to make my life a bit easier when it comes to soldering, but if the best option turns out to be an exposed pad DFN package, I won't bitch too much about dragging out the old rework station.
Any feedback would be greatly appreciated! I'll be digging deep on the IC research myself, so I'll keep everyone updated if I end up finding something (and if anybody's actually interested).

Thanks guys!
