MAX17055 7μA 1-Cell Fuel Gauge with ModelGauge m5 EZ General Description The MAX17055 is a low 7μA operating current fuel gauge that implements Maxim ModelGauge™ m5 EZ algorithm. ModelGauge m5 EZ makes fuel gauge implementation easy by eliminating battery characterization requirements and simplifying host software interaction. The ModelGauge m5 EZ robust algorithm provides tolerance against battery diversity for most lithium batteries and applications. ModelGauge m5 EZ algorithm combines the short-term accuracy and linearity of a coulomb counter with the longterm stability of a voltage-based fuel gauge, along with temperature compensation to provide industry-leading fuel gauge accuracy.
