Allegro MicroSystems A3281LLTTR is a Hall Effect digital switch latch. This device features an open collector output and requires a supply voltage range of 4.2V to 24V, with a maximum supply current of 8mA. The output current capability is up to 25mA. Designed for surface mounting, it utilizes the SOT-89-3 (TO-243AA) package, supplied on tape and reel. The A3281LLTTR exhibits a latching function, responding to the South Pole of a magnetic field with a trip point of 9mT and a release point of -9mT. This component is suitable for applications in automotive and industrial sectors where precise magnetic sensing and latching behavior are critical. The operating temperature range is -40°C to 150°C.
