The 10-FCCSP package (1.37x2.01 mm) keeps the footprint small enough for a single-cell Li-ion pack embedded in a wearable or handheld device. ## Cross-reference to STC3115 variants The GG25LJ shares the OptimGauge™ family and I²C battery-monitor function with the STC3115IJT, STC3115AIJT, and STC3115IQT. All four parts operate over the same -40°C to 85°C range and use surface-mount packages. The key difference is the package variant — the GG25LJ comes in a 10-FCCSP (1.37x2.01 mm), while the STC3115IJT and its siblings use different package outlines. Confirm the PCB land pattern before substituting one for the other.","metaTitle":"STMicro GG25LJ Battery Monitor, I²C, 10-FCCSP","metaDescription":"GG25LJ battery monitor IC from STMicro OptimGauge series.
