Design a Custom BoardAbout This Component
Single-cell Li-Ion battery charger IC in 16-pin QFN package. Integrates power transistor and control circuitry for autonomous charging with programmable charge current via external resistor. Typical applications include portable electronics, power banks, and IoT devices requiring compact battery management solutions.
Package: QFN-16 (3×3mm) · 16 pins
Why does this need a breakout?
This 3×3mm QFN with 0.5mm pitch requires a breakout board to hand-solder reliably—the fine pitch and sub-millimeter pad spacing make direct assembly impractical without professional equipment. The breakout converts the hidden pads to accessible 0.1" spaced pins, enabling breadboard prototyping of energy harvesting and battery management circuits.
