The STC3117IJT 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.
