Allegro MicroSystems A1147ELHLT is a unipolar Hall Effect switch designed for demanding applications. This digital switch features a current source output and is housed in a compact SOT-23W package, ideal for surface mount integration. The device operates within a supply voltage range of 3.5V to 24V, with a maximum supply current of 17mA. It exhibits a typical trip field of 8mT and a release field of 1mT, requiring a south pole magnetic field for activation. Qualified to AEC-Q100 standards and designed for automotive-grade performance, the A1147ELHLT is suitable for use in automotive systems, industrial controls, and consumer electronics requiring robust magnetic sensing capabilities. The component is supplied on tape and reel.
