Design a Custom BoardAbout This Component
Single-cell lithium-ion battery charger IC in 16-pin QFN package. Integrates power FET and charger controller for autonomous charging with programmable charge current and voltage. Supports USB and AC adapter inputs with integrated protection features including overvoltage, overcurrent, and thermal shutdown for portable consumer devices.
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.
