I know its a long time since the OP, but ..
I've been using the MAX17055 in a product, and the result has not been as good as promised by the marketing hoopla. Mostly I find the chip reports remaining charge to be far less than reality, meaning it reports "empty" far too soon.
Maybe its the Panasonic NCR li-Ion batteries I'm using, maybe its my application (lots of deep sleep, with short bursts of high current activity), maybe I've screwed up a register setting. Or maybe the chip doesn't work as advertised.
I'm still hunting for an answer - Maxim tech support had nothing useful to offer.
