MAX17047 ModelGauge m3电量计

The MAX17047 incorporates 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.
