MAX17047/MAX17050
1-Cell Fuel Gauge with ModelGauge m3
General Description
The MAX17047/MAX17050 incorporate the Maxim ModelGauge™ 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.
