Battery Fuel Gauge LSI [Smart LiB Gauge] for 1-Cell Lithium-ion/ Polymer (Li+) with Low Power 2 mA Operation LC709204F Overview LC709204F is a Fuel Gauge for 1 Cell Lithium ion/Polymer batteries.

It is part of our Smart LiB Gauge family of Fuel Gauges which measure the battery RSOC (Relative State Of Charge) using its unique algorithm called HG CVR2.

The HG CVR2 algorithm provides accurate RSOC information even under unstable conditions (e.g.

changes of battery; t
