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.ApplicationsSmartphones, Tablets, and 2-in-1 LaptopsSmartwatches and WearablesMedical Devices, Health and Fitness MonitorsDigital Still, Video, and Action CamerasHandheld Computers and TerminalsHandheld RadiosHome and Building Automation, SensorsSmart Batteries

The MAX17320 is a 38µA IQ stand-alone pack-side fuel gauge IC with protector, battery internal self-discharge detection, and optional SHA-256 authentication for 2 to 4 series lithium-ion/polymer batteries.The IC monitors the voltage, current, temperature and state of the battery to provide protection against over/undervoltage, overcurrent, short-circuit, over/undertemperature, overcharge, and internal self-discharge conditions using external high-side N-FETs, and provides charging prescription to ensure that the battery operates under safe conditions, thereby prolonging the life of the battery. The IC balances the cells using internal FETs. During prequal charging, the IC uses the CHGFET to linearly control charging.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 Maxim 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.The IC provides a configurable always-on LDO that can power small critical loads on the system side without overloading the cells even under fault 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/SMBus interface provides access to data and control registers.
