MAX1720x & MAX1721x ModelGauge m5 Fuel Gauges

Maxim Integrated MAX1720x & MAX1721x ModelGauge m5 Fuel Gauges are stand-alone ICs that are excellent pack-side fuel gauges. The MAX1720x and MAX1721x implement the Maxim ModelGauge™ m5 algorithm without requiring host interaction for configuration. 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 SHA-256 authentication with a 160-bit secret key. Each IC incorporates a unique 64-bit ID.
