LC709203F
Smart LiB Gauge
Battery Fuel Gauge LSI
for 1-Cell Lithium-ion (Li+)
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 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. It has minimal
parameters to be set by the user enabling simple, quick setup and
operation.
