MAX17260 Datasheet | Maxim Integrated

Description The MAX17260 is an ultra-low power fuel gauge IC which implements the Maxim Model Gauge™ m5 algorithm. The IC monitors a single-cell battery pack and supports both high-side and low-side current sensing. The Model Gauge m5 EZ algorithm makes fuel gauge implementation easy by eliminating battery characterization requirements and simplifying host software interaction. The algorithm provides tolerance against battery diversity for most lithium batteries and applications. The algorithm bines the short-term accuracy and linearity of a coulomb counter with the long-term stability of a voltagebased fuel gauge, along with temperature pensation to provide industry-leading fuel gauge accuracy. The IC automatically pensates for cell-aging, temperature, discharge rate, and provides accurate state-of-charge (SOC) in percentage (%) and remaining capacity in milliampere-hours (m Ah) 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 tiny lead-free 0.4mm pitch, 1.5mm x 1.5mm, 9-pin WLP package and 3mm x 3mm, 14-pin TDFN package.
