MAX17047/MAX17050 1-Cell Fuel Gauge with Model Gauge m3 General Description The MAX17047/MAX17050 incorporate the Maxim Model Gauge™ m3 algorithm that bines the excellent short-term accuracy and linearity of a coulomb counter with the excellent long-term stability of a voltage-based fuel gauge, along with temperature pensation to provide industry-leading fuel-gauge accuracy. Model Gauge m3 cancels offset accumulation error in the coulomb counter, while providing better short-term accuracy than any purely voltage-based fuel gauge. Additionally, the Model Gauge m3 algorithm does not suffer from abrupt corrections that normally occur in coulomb-counter algorithms, since tiny continual corrections are distributed over time. The device automatically pensates for aging, temperature, and discharge rate and provides accurate state of charge (SOC) in m Ah or %, as well as time-to-empty over a wide range of operating conditions. The device provides two methods for reporting the age...
