1-Cell Fuel Gauge with ModelGauge m3
General Description
The MAX17047/MAX17050 incorporate the Maxim ModelGaugeā¢ m3 algorithm that combines 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 compensation to provide industry-leading fuel-gauge accuracy. ModelGauge m3 cancels offset accumulation error in the coulomb counter, while providing better short-term accuracy than any purely voltage-based fuel gauge. Additionally, the ModelGauge 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 compensates for aging, temperature, and discharge rate and provides accurate state of charge (SOC) in mAh or %, as well as time-to-empty over a wide range of operating conditions. The device provides two methods for reporting the age of ...
