Analog Devices Inc. MAX17261 Fuel Gauge ICs are designed to use the ModelGauge™ m5 algorithm to monitor multiple-series cell battery packs with an external resistor divider. The ModelGauge m5 algorithm simplifies host software integration and eliminates battery characterization requirements, making fuel gauge implementation easy. ADI MAX17261 ICs feature a 1mΩ to 1000mΩ wide sense resistor range, PCB metal sensing, temperature compensation, thermistor, time-to-empty, and time-to-full estimation. The algorithm provides industry-leading fuel gauge accuracy by combining the linearity of a coulomb counter and short-term accuracy with the long-term stability of a voltage-based fuel gauge.
