1 / 31 page  This is information on a product in full production. January 2014 DocID023755 Rev 4 1/31 STC3115 Gas gauge IC with alarm output for handheld applications Datasheet - production data Features • OptimGaugeTM algorithm • 0.25% accuracy battery voltage monitoring • Coulomb counter and voltage-mode gas gauge operations • Robust initial open-circuit-voltage (OCV) measurement at power up with debounce delay • Low battery level alarm output with programmable thresholds • Internal temperature sensor • Battery swap detection • Low power: 45 µA in power-saving mode, 2 µA max in standby mode • 1.4 x 2.0 mm 10-bump CSP package Applications • Mobile phones, multimedia players, digital cameras • Portable medical equipment Description The STC3115 includes the hardware functions required to implement a low-cost gas gauge for battery monitoring. The STC3115 uses current sensing, Coulomb counting and accurate measurements of the battery voltage to estimate the state-of-charge (SOC) of the battery. An internal temperature sensor simplifies implementation of temperature compensation. An alarm output signals a low SOC condition and can also indicate low battery voltage. The alarm threshold levels are programmable. The STC3115 offers advanced features to ensure high performance gas gauging in all application conditions. CSP (1.4 x 2.0 mm) www.st.com |
