The MAX17055 is a low 7μA operating current fuel gauge which 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 long-term stability of a voltage-based fuel gauge, along with temperature compensation to provide industry-leading fuel gauge accuracy. The MAX17055 automatically compensates for cell aging, temperature, and discharge rate, and provides accurate state of charge (SOC in %) and remaining capacity in milliampere-hours (mAh). As the battery approaches the critical region near empty, the ModelGauge m5 algorithm invokes a special error correction mechanism that eliminates any error. It also provides three methods for reporting the age of the battery: reduction in capacity, increase in battery resistance, and cycle odometer.
The MAX17055 provides precision measurements of current, voltage, and temperature. Temperature of the battery pack is measured using an internal temperature measurement or external thermistor. A 2-wire I²C interface provides access to data and control registers.
The MAX17055 is available in a lead-free, tiny 0.4mm Pitch 1.4mm x 1.5mm, 9-pin WLP package, and a 2mm x 2.5mm, 10-pin TDFN package.
