MAX17260 - Maxim Integrated

MAX17260 1-Cell Fuel Gauge

The MAX17260 is an ultra-low power fuel gauge IC which implements the Maxim ModelGauge™ m5 algorithm. The IC monitors a single-cell battery pack and supports both high-side and low-side current sensing. The ModelGauge m5 EZ algorithm makes fuel gauge implementation easy by eliminating battery characterization requirements and simplifying host software intera.
