Smart LiB Gauge Battery Fuel Gauge LSI For 1‐Cell Lithium‐ion/ Polymer (Li+) LC709203F Overview LC709203F is a Fuel Gauge for a single lithium ion/polymer battery. 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−CVR. The HG−CVR algorithm eliminates the use of a sense resistor and provides accurate RSOC information even under unstable conditions (e.g. changes of battery; temperature, loading, aging and self-discharge). An accurate RSOC contributes to the operating time of portable devices. LC709203F is available in two small packages realizing the industries smallest PCB footprint for the complete solution.
