                  Description:
                   
                  The LTC2944 measures battery charge state, battery volt-age, 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. Voltage, current and temperature are measured with an internal 14-bit No Latency ΔΣ™ ADC. The measurements are stored in internal registers accessible via the onboard I2C/SMBus Interface.
                  The LTC2944 features programmable high and low thresh-olds for all four measured quantities. If a programmed threshold is exceeded, the device communicates an alert using either the SMBus alert protocol or by setting a flag in the internal status register. The LTC2944 requires only a single low value sense resistor to set the measured current range.
