STEVAL-ISB017V1 STMicroelectronics

STEVAL-ISB017V1 Data brief STC3117 evaluation board Features Patented OptimGaugeTM algorithm for accurate battery capacity calculation Robust initial open-circuit-voltage (OCV) measurement at power up Programmable low battery alarm Missing/swapped battery detection Average current internal calculation End-of-Charge detection Internal temperature sensor Battery swap detection with protection against false battery insertion Low power 40 A in voltage-only, 2uA max. in standby mode 1.49 x 1.594 mm 9-bump CSP package RoHS compliant 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.
