MAX17215

MAX17201/MAX17205/ MAX17211/MAX17215 EVALUATION KIT AVAILABLE 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 configuration. This feature makes the MAX1720x/MAX1721x excellent pack-side fuel gauges. The MAX17201/MAX17211 monitor a single cell pack. 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 SHA256 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 longterm 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 disc...
