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.

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
