MAX17058/MAX17059 EVALUATION KIT AVAILABLE 1-Cell/2-Cell Fuel Gauge with ModelGauge General Description The MAX17058/MAX17059 ICs are tiny fuel gauges for lithium-ion (Li+) batteries in handheld and portable equipment. The MAX17058 operates with a single Li+ cell and the MAX17059 with two Li+ cells in series. The ICs use the sophisticated Li+ battery-modeling algorithm ModelGauge™ to track the battery relative state-of-charge (SOC) continuously over a widely varying charge/discharge conditions. The ModelGauge algorithm eliminates current-sense resistor and battery-learn cycles required by other fuel gauges. Temperature compensation is implemented using the system micro-controller.
