Design a Custom BoardAbout This Component
I2C bus redriver and hot-swap controller IC in 8-pin VSSOP package. Designed to extend I2C bus range by actively driving SDA and SCL lines while providing hot-swap functionality for safe insertion/removal of modules. Supports standard and fast-mode I2C operation with integrated charge pump for voltage regulation.
Package: MSOP-8 · 8 pins
Why does this need a breakout?
The 0.65mm pitch and tiny 3×3mm form factor make hand soldering challenging and impractical for breadboard prototyping. A breakout board converts this compact SMD package into a standard header layout, enabling reliable connections and rapid iteration without specialized soldering equipment or rework risk.
