MAX17055 fuelgauge. Any experience?
(1/1)
plazma:
I have worked with products with TI coulomb counter fuelgauges and software fuelgauge based on characterization tables. The SW based worked better than the TI chip.
A newsletter caught my attention to Maxim MAX17055 fuelgauge https://www.maximintegrated.com/en/products/power/battery-management/MAX17055.html
Does anyone have experience with this?
Looks interesting though we have bad experience with Maxim chip availability.

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.
