  • 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.

    Key Features

    • Patented OptimGauge™ 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 μA in voltage-only mode, 2 μA max in standby mode
    • 1.49 x 1.594 mm 9-bump CSP package
