概览

LC709209F is a Fuel Gauge(in other words, Fuel Gauge IC, Gas Gauge, Battery Monitor or Battery Gauge) for 1-Cell(1series N parallel) 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. The Fuel Gauge feature of the HG−CVR2 algorithm makes it highly applicable in various applications. The device can immediately start battery measurement by setting a few parameters after battery insertion, without the need for long learning cycles that can complicate the application development process.
