DATA SHEET www.onsemi.com Battery Fuel Gauge [Smart LiB Gauge] for 1-Cell Lithium-ion/ Polymer (Li+) with Low Power 2 mA Operation WLCSP12 1.48x1.91x0.51 CASE 567XE MARKING DIAGRAM LC709209F Overview LC709209F is a Fuel Gauge (in other words, Fuel Gauge IC, Gas Gauge, Battery Monitor or Battery 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; temperature, loading, aging and self−discharge). An accurate RSOC contributes to the operating time of portable devices.
