onsemi LC709209F Battery Fuel Gauges are used for 1-Cell (1series N parallel) Lithium-Ion/Polymer batteries. The onsemi LC709209F is part of the Smart LiB Gauge family of fuel gauges which measure the battery’s Relative State Of Charge (RSOC). The devices use a unique algorithm called HG-CVR2. The HG−CVR2 algorithm provides accurate RSOC information even under unstable conditions (e.g., changes in battery, temperature, loading, aging, and self−discharge).
