Allegro MicroSystems A3281LLTTR-T is a Hall Effect latching switch designed for robust operation in demanding environments. This digital switch features an open collector output, capable of sourcing up to 25mA, and operates within a supply voltage range of 4.2V to 24V with a maximum quiescent current of 8mA. The device is sensitive to the south pole of a magnet, with trip and release points specified at 9mT and -9mT respectively. Packaged in a SOT-89-3 (TO-243AA) surface mount configuration, it is supplied on tape and reel. The A3281LLTTR-T is suitable for applications requiring precise magnetic sensing and switching, including automotive systems, industrial automation, and consumer electronics. Its operating temperature range extends from -40°C to 150°C (TA).
