The MAX17300–MAX17303/MAX17310–MAX17313 is a 24μA IQ stand-alone pack-side fuel gauge IC with protector 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 conditions 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 combines 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, temperature, 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 I2C 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.
