IC REDRIVER I2C HOTSWAP 8-VSSOP


Bypass caps, pull-ups, strapping resistors, custom silkscreen & more
Design a Custom BoardI2C 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.
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.
