DESCRIPTION

· The MAX17047/MAX17050 integrate the ModelGauge™ m3 algorithm, combining coulomb counter accuracy with voltage-based fuel gauge stability.

· The devices offer temperature compensation, aging, and discharge rate adjustments for precise state of charge (SOC) and time-to-empty estimations.

· They feature a 2-wire I2C interface and are available in compact, lead-free packages: 10-pin TDFN for MAX17047 and 9-bump WLP for MAX17050.

FEATURES

· Accurate battery capacity and time-to-empty estimation with temperature, age, and rate compensation.

· Precision measurement system without the need for calibration.

· ModelGauge m3 algorithm ensures long-term stability and short-term accuracy.

· External temperature measurement network with actively switched thermistor resistive divider.

· Low quiescent current: 25μA active, < 0.5μA shutdown.

· Alert indicators for SOC, voltage, temperature, and battery removal/insertion events.

· AtRate estimation of remaining capacity.

APPLICATIONS

· Smartphones and tablets.

· Health and fitness monitors.

· Digital still, video, and action cameras.

· Medical devices.

· Handheld computers and terminals.

· Wireless speakers.
