Design a Custom BoardAbout This Component
Standalone battery fuel gauge and monitor supporting multiple chemistry types including Li-Ion, Li-Po, and lead-acid. Integrates voltage measurement, coulomb counting, and impedance tracking for accurate state-of-charge and state-of-health estimation. Communicates via I2C interface for real-time battery metrics in portable devices, power tools, and energy storage systems.
Package: TSSOP-14 (4.4×5mm) · 14 pins
Why does this need a breakout?
The 0.65mm pitch on this 14-pin package makes hand soldering tedious and error-prone without magnification and fine tools. A breakout board routes each pin to standard 0.1-inch headers, enabling breadboard prototyping and simplifying connections for LIN transceivers, ADCs, digital potentiometers, and microcontrollers that typically come in this footprint.
