STC3117

STC3117 Gas gauge IC with battery charger control for handheld applications CSP (1.49 x 1.594 mm) Datasheet - production data 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. 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 Applications  Mobile phones, multimedia players, digital cameras  Portable medical equipment November 2017 This is information on a product in full production.
