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
