1 / 34 page  This is information on a product in full production. January 2015 DocID025792 Rev 2 1/34 STC3117 Gas gauge IC with battery charger control for handheld applications Datasheet - production data 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 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. CSP (1.49 x 1.594 mm) www.st.com |
