Design a Custom BoardAbout This Component
Omnipolar Hall-effect switch IC detecting magnetic fields from either North or South poles with medium sensitivity. Operating range 2.5V to 5.5V with ultra-low 24µW quiescent current at 3V, featuring chopper-stabilized architecture for superior temperature stability and minimal drift. Single open-drain output suitable for tamper detection, position sensing, and contactless switching in battery-powered and industrial applications.
Package: SOT-23-3 · 3 pins
Why does this need a breakout?
SOT-23's tiny 0.95mm pin pitch and compact form factor make hand-soldering tedious and prone to bridging errors. A breakout board breaks out the three pins to standard 0.1" spacing for breadboard prototyping, eliminating the need for specialized soldering equipment and enabling fast circuit iteration with transistors, diodes, and small-signal components.
