General Description

The MAX17048/MAX17049 ICs are tiny, micropower current fuel gauges for lithium-ion (Li+) batteries in handheld and portable equipment.

The MAX17048 operates with a single lithium cell and the MAX17049 with two lithium cells in series.

The ICs use the sophisticated Li+ battery-modeling algorithm ModelGaugeK to track the battery relative state-of-charge (SOC) continuously over widely varying charge and discharge conditions.
