Design a Custom BoardAbout This Component
Quad independent voltage comparator operating from 1.65V to 5.5V supply with rail-to-rail inputs and open-drain outputs. Features 600ns typical propagation delay, 400µV input offset voltage, and power-on-reset function. Suitable for automation, motor drives, and power management applications across industrial and consumer equipment.
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.
