MAX17263 Fuel Gauge IC Analog Devices MAX17263 Fuel Gauge IC is an ultra-low power IC that implements the Analog Devices ModelGauge™ m5 algorithm. This algorithm makes easy fuel gauge implementation by eliminating the battery characterization requirements and simplifying host software interaction. The MAX17263 IC monitors a single-cell or multiple-series cell battery pack with an external resistor divider. This IC drives 3 to 12 automatically-counted LEDs to indicate the battery State-Of-Charge (SOC) on a push-button press or system status using I2C commands.
