and Internal Current Sensing General Description Benefits and Features The MAX17262 is an ultra-low power fuel-gauge IC which
implements the Maxim ModelGauge™ m5 algorithm. The
IC monitors a single-cell battery pack and supports internal current sensing for up to 3.1A pulse current. The IC
provides best performance for batteries with 100mAhr to
6Ahr capacity. ● ModelGauge m5 EZ
• No Characterization Required for EZ
Performance
• Robust Against Battery Variation
• Eliminates Error Near Empty Voltage
• Eliminates Coulomb-Counter Drift
• Compensates for Age, Current, Temperature
• Does Not Require Empty, Full, or Idle States The ModelGauge m5 EZ makes fuel-gauge implementation easy by eliminating battery characterization requirements and simplifying host software interaction. The
ModelGauge m5 EZ robust algorithm provides tolerance
against battery diversity for most lithium batteries and
applications.
The ModelGauge m5 EZ algorithm combines the shortterm accuracy and linearity of a coulomb counter with the
long-term stability of a voltage-based fuel gauge, along
with temperature compensation to provide industry-leading fuel-gauge accuracy. The IC automatically compensates for cell-aging, temperature, and discharge rate,
and provides accurate state-of-charge (SOC) in percentage (%) and remaining capacity in milliampere-hours
(mAh) over a wide range of operating conditions. As
the battery approaches the critical region near empty, the ModelGauge m5 algorithm invokes a special correction mechanism that eliminates any error. The IC provides accurate estimation of time-to-empty and time-tofull and provides three methods for reporting the age of
the battery: reduction in capacity, increase in battery resistance, and cycle odometer. …
