Hi,

I am trying to use DS2782 as a fuel gauge for my 850 mAh Li-Po battery. I a=
m able to interface to the fuel gauge and read data from the fuel gauge. I =
am not able to understand its operation correctly. My goal is to estimate t=
he remaining battery capacity.

The voltage of the battery is available as a 16 bit number and I am able to=
 read that through the I2C interface(I haven't verified the measured voltag=
e using a DMM yet). The datasheet provides parameters like remaining capaci=
ty in % as an 8 bit number. If I try to read that, I always get a 0.=A0

There is an application note=A0that explains how to use the battery gauge. =
They talk about cell characterization where they explain that the gauge nee=
ds to go through a learning cycle.=A0

I am not using the gauge in an evaluation kit but a small board that I desi=
gned. I am sure that someone might have used a similar gauge in their appli=
cation. Is it as simple as subjecting the battery through a charge and disc=
harge cycle?

The datasheet explains a lot of parameters and I am quite confused about us=
ing the gauge.

Thanks,
Sai
