Design a Custom BoardAbout This Component
Ultra-sensitive, pole-independent Hall-effect switch with latched digital output in SOT-23W package. Operates on 2.4 to 5.5V supply with typical average current of 309µA, featuring chopper-stabilized offset cancellation for superior temperature stability and minimal drift. Omnipolar design responds to either north or south magnetic poles, replacing reed switches in battery-powered handheld equipment, automotive applications, and proximity sensing.
Package: SOT-23W · 3 pins
Why does this need a breakout?
SC-59's 0.95mm pin pitch and three-lead configuration make hand-soldering impractical and breadboard prototyping impossible. A breakout board converts these tiny SMD pads to standard headers, enabling quick integration of analog switches, hall-effect sensors, and low-voltage logic gates into development circuits without specialized soldering equipment.
