STC3115IJT ST Battery Management IC | 10-CSP (1.4x2.04) | Fuel Gauge, Low Power

Product Overview

The STC3115IJT is a high-performance battery fuel gauge IC from STMicroelectronics, designed for accurate state-of-charge (SoC) monitoring in portable and embedded applications. Housed in a compact 10-CSP (1.4x2.04 mm) package, it integrates a precision coulomb counter and voltage measurement to provide reliable battery status information. With ultra-low power consumption (typical 45 µA in active mode), it extends battery life in energy-sensitive designs. The device communicates via I2C interface and supports a wide voltage range (2.7V to 4.8V), making it suitable for single-cell Li-ion/Li-Polymer batteries.
