General Description:
The MAX17043/MAX17044 are ultra-compact, low-cost,
host-side fuel-gauge systems for lithium-ion (Li+) batteries in handheld and portable equipment. The MAX17043
is configured to operate with a single lithium cell and the
MAX17044 is configured for a dual-cell 2S pack.
The MAX17043/MAX17044 use a sophisticated Li+ battery-modeling scheme, called ModelGauge™ to track
the battery’s relative state-of-charge (SOC) continuously
over a widely varying charge/discharge profile. Unlike
traditional fuel gauges, the ModelGauge algorithm eliminates the need for battery relearn cycles and an external
current-sense resistor. Temperature compensation is possible in the application with minimal interaction between a μC and the device.
The IC can be located on the system side, reducing cost and supply chain constraints on the battery. Measurement and estimated capacity data sets are accessed through an I2C interface. The MAX17043/MAX17044 are available in either a 0.4mm pitch 9-bump UCSP™ or 2mm x 3mm, 8-pin TDFN lead-free package.
