Stand-Alone ModelGauge m5 Fuel Gauge
with SHA-256 Authentication
General Description
The MAX1720x/MAX1721x are ultra-low power stand-alone
fuel gauge ICs that implement the Maxim ModelGauge™
m5 algorithm without requiring host interaction for configura-
tion. This feature makes the MAX1720x/MAX1721x excellent
pack-side fuel gauges. The MAX17201/MAX17211 monitor a
single cell pack. The MAX17205/MAX17215 monitor and bal-
ance a 2S or 3S pack or monitor a multiple-series cell pack.
To prevent battery pack cloning, the ICs integrate SHA-
256 authentication with a 160-bit secret key. Each IC
incorporates a unique 64-bit ID.
The ModelGauge™ m5 algorithm combines the short-term
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 pro-
vides accurate state of charge (SOC) in milliampere-hours
(mAh) or percentage (%) over a wide range of operating
conditions. As the battery approaches the critical region
near empty, the ModelGauge m5 algorithm invokes a spe-
cial error correction mechanism that eliminates any error.
The ICs provide accurate estimation of time-to-empty and
time-to-full, Cycle+™ age forecast, and three methods
for reporting the age of the battery: reduction in capacity,
increase in battery resistance, and cycle odometer.
The ICs provide precision measurements of current, voltage,
and temperature. Temperature of the battery pack is mea-
sured using an internal temperature measurement and up to
two external thermistors supported by ratiometric measure-
ments on auxiliary inputs. A Maxim 1-Wire
®
(MAX17211/
MAX17215) or 2-wire I
2
C (MAX17201/MAX17205) inter-
face provides access to data and control registers. The ICs
are available in lead-free, 3mm x 3mm, 14-pin TDFN and
1.6mm x 2.4mm 15-bump WLP packages.
