The MAX17263 is an ultra-low power fuel gauge which implements Maxim ModelGauge™ m5 EZ algorithm. The MAX17263 monitors either a single cell battery pack or multiple-series cell battery pack with an external resistor divider. The IC drives 3 to 12 automatically-counted LEDs to indicate battery state-of-charge on a push-button press, or any other system status using I2C commands.

ModelGauge m5 EZ makes fuel gauge implementation easy by eliminating battery characterization requirements and simplifying host software interaction. The ModelGauge m5 EZ robust algorithm provides tolerance against battery diversity for most lithium batteries and applications.

The algorithm combines the short-term accuracy and linearity of a coulomb counter with the long-term stability of a voltage-based fuel gauge, along with temperature compensation to provide industry-leading fuel-gauge accuracy. The IC automatically compensates for cell-aging, temperature, and discharge rate, and provides accurate state-of-charge (SOC) in percentage (%) and remaining capacity in milliampere-hours (mAh) over a wide range of operating conditions. As the battery approaches the critical region near empty, the algorithm invokes a special correction mechanism that eliminates any error. The IC provides accurate estimation of time-to-empty and time-to-full and provides three methods for reporting the age of the battery: reduction in capacity, increase in battery resistance, and cycle odometer.

The IC provides precision measurements of current, voltage, and temperature. The temperature of the battery pack is measured using an internal temperature sensor or external thermistor. A 2-wire I2C interface provides access to data and control registers. The IC is available in a 3mm x 3mm 14-pin TDFN package.
