MAX17201/5 and MAX17211/5 Fuel Gauge ICs
Analog Devices offers its first stand-alone ModelGauge™ m5 fuel gauge ICs with SHA-256 authentication
Analog Devices' MAX17201/5 and MAX17211/5 are ultra-low-power, stand-alone fuel gauge integrated circuits (ICs) that implement the Analog Devices ModelGauge m5 algorithm without requiring host interaction for configuration. This feature makes the MAX17201/5 and MAX17211/5 excellent pack-side fuel gauges. The MAX17201/MAX17211 monitor a single cell pack and the MAX17205/MAX17215 monitor and balance 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 also provides 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 special 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. The temperature of the battery pack is measured using an internal temperature measurement and up to two external thermistors supported by ratio-metric measurements on auxiliary inputs. A Analog Devices 1-Wire® (MAX17211/MAX17215) or 2-wire I2C (MAX17201/MAX17205) interface provides access to data and control registers. The ICs are available in lead-free, 3 mm x 3 mm, 14-pin TDFN and 1.6 mm x 2.4 mm, 15-bump WLP packages.
(note: 00E indicates ICs support EZ performance model only. No custom battery characterization.)
