Allegro MicroSystems A1143ELHLT-T is a unipolar Hall effect switch designed for automotive applications conforming to AEC-Q100 standards. This digital switch features a current source output and is packaged in a SOT-23W surface-mount component. Optimized for sensing magnetic fields, it offers a typical trip point of 11mT and a release point of 4.5mT, with sensitivity to the south pole of a magnet. Operating across a voltage supply range of 3.5V to 24V, the device has a maximum supply current of 17mA. The A1143ELHLT-T is suitable for various automotive systems requiring robust magnetic sensing capabilities, operating reliably within a temperature range of -40°C to 85°C. It is supplied in Tape & Reel packaging.
