The MAX17263LETD+T from Analog Devices (Maxim Integrated) is an ultra-low power fuel-gauge integrated circuit that utilizes the Maxim ModelGauge m5 EZ algorithm. This algorithm simplifies fuel gauge implementation by eliminating battery characterization requirements and reducing host software interaction.
The IC is designed to monitor either single-cell or multiple-series cell battery packs, using an external resistor divider for multi-cell configurations. It offers accurate measurements of current, voltage, and temperature, with the temperature being measured via an internal sensor or an external thermistor. The ModelGauge m5 EZ algorithm combines coulomb counter accuracy with voltage-based fuel gauge stability, compensating for cell aging, temperature, and discharge rate to provide precise state-of-charge (SOC) in percentage and remaining capacity in milliampere-hours (mAh).
Key features include tolerance against battery diversity for most lithium batteries, elimination of errors near empty voltage, and compensation for battery aging, current, and temperature. The device supports a wide sense resistor range from 1mΩ to 1000Ω and includes integrated LED control for battery state indication. Communication is handled via a 2-wire I2C interface.
The MAX17263LETD+T is available in a compact 3mm x 3mm 14-pin TDFN package, suitable for surface mounting. Its applications span across various portable electronic devices, including wireless speakers, medical devices, drones, power tools, e-bikes, and headlamps.
