MAX17263 Single/Multi-Cell Fuel Gauge with ModelGauge m5 EZ and Integrated LED Control General Description The MAX17263 is an ultra-low power fuel-gauge IC which implements the Maxim ModelGauge™ m5 algorithm. The IC monitors either a single cell battery pack or multiple-series cell battery pack with an external resistor divider. The IC drives 3 to 12 automatically-counted LEDs to indicate battery state-of-charge on a push-button press, or any other system status using I2C commands. The ModelGauge m5 EZ algorithm makes fuel gauge implementation easy by eliminating battery characterization requirements and simplifying host software interaction. The algorithm provides tolerance against battery diversity for most lithium batteries and applications. The 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 te...
