    Tiny, Accurate Battery Gas Gauges with Easy-to-Use I2C
    Interface and Optional Integrated Precision Sense Resistors
    Christoph Schwoerer, Axel Klein and Bernhard Engl Imagine your daughter is catching her first wave on a
    surfboard and your video camera shuts down because the
    battery—reading half full when you started filming a few
    minutes ago—is suddenly empty. The problem is inaccurate
    battery gas gauging. Inaccurate fuel gauging is a common
    nuisance as many portable devices derive remaining
    battery capacity directly from battery voltage. This method
    is cheap but inaccurate since the relationship between
    battery voltage and capacity has a complex dependency
    on temperature, load conditions and usage history.
    More accurate battery gauging can be
    achieved by monitoring not only the
    battery voltage but also by tracking the
    charge that goes in and out of the battery. For applications requiring accurate
    battery gas gauging, the LTC2941 and
    LTC2942 coulomb counters are tiny and
    easy-to-use solutions. These feature-rich
    devices are small and integrated enough to
    fit easily into the latest handheld gadgets.
    The LTC2941 is a battery gas gauge device
    designed for use with single Li-Ion cells ...
