description: |
The STC3117 includes the STMicroelectronics OptimGauge algorithm.
It provides accurate battery state-of-charge (SOC) monitoring, tracks
battery parameter changes with operation conditions, temperature,
and aging, and allows the application to get a battery state-of-health
(SOH) indication.
An alarm output signals low SOC or low voltage conditions and also
indicates fault conditions like a missing or swapped battery.
