Design a Custom BoardAbout This Component
Single-cell lithium-ion battery charger IC in 24-pin WQFN package. Integrates power path management, charge control, and protection functions for portable devices. Supports fast charging with programmable current and voltage limits via I2C interface.
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.
