The Allegro MicroSystems A3281ELHLT is a Hall Effect digital switch latch, available in a SOT-23W package. This device operates with an open-collector output and is designed for surface mount applications. It exhibits a latching function, requiring both a north and south pole to operate, with a specified sensing range of 9mT trip and -9mT release for the south pole. The operating temperature range is -40°C to 85°C. This component is suitable for applications requiring precise magnetic actuation and is commonly found in automotive systems, industrial controls, and consumer electronics. The supply voltage range is 4.2V to 24V, with a maximum supply current of 8mA and a maximum output current of 25mA. The A3281ELHLT is supplied on tape and reel.
