BQ35100PWR Breakout

About This Component

Battery monitor and fuel gauge IC supporting multiple battery chemistries including Li-Ion, Li-Po, and lead-acid. Integrates high-precision coulomb counter, voltage measurement, and temperature sensing with I2C interface for real-time capacity and health monitoring. Commonly used in portable devices, power tools, and UPS systems requiring accurate remaining capacity estimation.

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.
