LC709203F: Battery Fuel Gauge for 1-Cell Lithium-Ion/Polymer Product Overview
●LC709203F is a Fuel Gauge for a single lithium ion 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 selfdischarge). 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. It has minimal parameters to be set by the user enabling simple, quick setup and operation.
