Design a Custom BoardAbout This Component
Single-cell lithium-ion battery charger IC with integrated power management. Features 5A charge current capability, adjustable input current limit, and comprehensive protection functions including overvoltage, overcurrent, and thermal shutdown. Designed for portable electronics, power banks, and consumer devices requiring fast-charging solutions in a compact 24-pin QFN package.
Package: QFN-24 (4×4mm) · 24 pins
Why does this need a breakout?
This 0.5mm pitch QFN is nearly impossible to hand solder and entirely incompatible with breadboards due to hidden pads beneath the package. A breakout board provides accessible headers and pre-soldered connections, letting you prototype with InvenSense motion sensors via I2C or SPI without specialized SMD equipment or rework skills.
