    and Discharge
    nn 3.6V to 60V Operating Range for Multiple Cells
    nn 14-Bit ADC Measures Voltage, Current
    and Temperature
    nn 1% Voltage, Current and Charge Accuracy
    nn ±50mV Sense Voltage Range
    nn High Side Sense
    nn I2C Interface/SMBus Interface
    nn General Purpose Measurements for Any Battery
    Chemistry and Capacity
    nn Configurable Alert Output/Charge Complete Input
    nn Quiescent Current Less Than 150µA
    nn Small 8-Lead 3mm × 3mm DFN Package The LTC®2944 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 60V. A precision coulomb
    counter integrates current through a sense resistor between
    the battery’s positive terminal and the load or charger. ...
