+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.
+
+ Datasheet is available at
+ https://www.st.com/resource/en/datasheet/stc3117.pdf
