    Small 8-Lead 3mm × 3mm DFN Package Applications The LTC®2943-1 measures battery charge state, battery
    voltage, battery current and its own temperature in portable
    product applications. The wide input voltage range allows
    use with multicell batteries up to 20V. A precision coulomb
    counter integrates current through a sense resistor between
    the battery’s positive terminal and the load or charger. ...
