Design a Custom BoardAbout This Component
Unipolar Hall-effect magnetic switch in SOT-23W package with integrated voltage regulator, amplifier, and NMOS output. Operates from 3.8–24V with factory-programmed switch point and low-noise BiCMOS design. AEC-Q100 automotive qualified for motor commutation and industrial applications with ±30V absolute maximum rating.
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.
