MAX17055EWL+ Fuel Gauge

Maxim’s MAX17055EWL+ 1-cell fuel gauge with ModelGauge m5 EZ algorithm

Image of Maxim's MAX17055EWL+ Fuel Gauge schematicsMaxim's MAX17055EWL+ is a low 7 μA operating current fuel gauge that provides precision measurements of current, voltage, and temperature. The fuel gauge uses Maxim's ModelGauge™ m5 EZ algorithm. 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.

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 variance for most lithium batteries and applications.

ModelGauge m5 EZ algorithm incorporates 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 MAX17055EWL+ 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 compensation 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.
