The TDK-Micronas GmbH HAL549SF-K is a unipolar Hall effect switch from the HAL® 54x series. This surface mount device, packaged in a SOT-89B-1 (TO-243AA, Variant), features an open-drain output and is designed for sensing the presence of a magnetic field's north pole. It offers a typical trip magnetic flux density of 5.5mT and a release flux density of 3.6mT, with operation specified at 25°C. The device operates over a wide temperature range of -40°C to 140°C. Key features include temperature compensation for consistent performance. The supply voltage range is 4.3V to 24V, with a maximum supply current of 4.2mA and a maximum output current of 20mA. This component is suitable for applications in automotive, industrial, and consumer electronics sectors requiring precise magnetic sensing.
