The MAX17301–MAX17303/MAX17311–MAX17313 is a
24μA I
Q
stand-alone pack-side fuel gauge IC with protec-
tor and optional SHA-256 authentication for 1-cell lithium-
ion/polymer batteries.
The IC monitors the voltage, current, temperature, and
state of the battery to provide against over/undervoltage,
overcurrent, short-circuit, over/undertemperature and
overcharge conditions protection using external high-side
N-FETs, and provides charging prescription to ensure that
the lithium-ion/polymer battery operates under safe condi-
tions prolonging the life of the battery.
To prevent battery pack cloning, the IC integrates
SHA-256 authentication with a 160-bit secret key. Each IC
incorporates a unique 64-bit ID.
The fuel gauge uses ModelGauge m5 algorithm that com-
bines the short-term accuracy and linearity of a coulomb
counter with the long-term stability of a voltage-based fuel
gauge to provide industry-leading fuel-gauge accuracy.
The IC automatically compensates for cell aging, temper-
ature, and discharge rate, and provides accurate state-of-
charge (SOC) in milliampere-hours (mAh) or percentage
(%) over a wide range of operating conditions.
Dynamic power functionality provides the instantaneous
maximum battery output power which can be delivered
to the system without violating the minimum system input
voltage.
A Maxim 1-Wire

or 2-wire I

C interface provides access
to data and control registers. The IC is available in a
lead-free, 3mm x 3mm 14-pin TDFN and 1.7mm x 2.5mm
15-bump 0.5mm pitch WLP packages.
