The Allegro MicroSystems A3280LLTTR-T is a Hall Effect latching magnetic switch designed for robust performance in demanding applications. This digital switch, featuring an open-collector output, operates effectively with supply voltages ranging from 4.2V to 24V, drawing a maximum of 8mA quiescent current and providing up to 25mA output current. Its latching function, activated by the south pole of a magnetic field, exhibits a typical trip point of 4mT and a release point of -4mT. Packaged in a SOT-89-3 (TO-243AA) surface-mount configuration, the A3280LLTTR-T is supplied on tape and reel for high-volume manufacturing. This component is suitable for industries such as automotive, industrial automation, and consumer electronics where reliable position sensing and speed detection are critical. The operating temperature range of -40°C to 150°C ensures consistent functionality across diverse environmental conditions.
