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.
