    MSOP Packages The LTC®2941 measures battery charge state in batterysupplied handheld PC and portable product applications.
    Its operating range is perfectly suited for single-cell Li-Ion
    batteries. A precision coulomb counter integrates current
    through a sense resistor between the battery’s positive
    terminal and the load or charger. The measured charge
    is stored in internal registers. An SMBus/I2C interface
    accesses and configures the device. Applications The LTC2941 requires only a single low value external
    sense resistor to set the current range. n Low Power Handheld Products Cellular Phones
    n MP3 Player
    n Cameras ...
