The Allegro Microsystems A1120LLHLX-T is a Hall-effect unipolar switch IC, part of the A112x series. It is engineered for exceptional temperature stability and resistance to physical stress, making it suitable for extended temperature ranges up to 150°C. This device integrates a voltage regulator, Hall-voltage generator, amplifier, chopper stabilization, Schmitt trigger, and a short-circuit protected open-drain output capable of sinking up to 25 mA.
Operating from a supply voltage of 3 V to 24 V, the A1120LLHLX-T is versatile for various applications, including those requiring lower voltage operation or enhanced protection against voltage transients. The switch points are sensitive to a south pole magnetic field, with a typical trip point of 5 mT and a release point of 0.5 mT. The device is available in a SOT-23W surface-mount package, facilitating integration into compact designs.
Key features include AEC-Q100 automotive qualification, output short-circuit protection, reverse-battery protection, and solid-state reliability. Its unipolar switching characteristic means a south pole of sufficient strength turns the output on, and removal of the magnetic field turns it off. The A1120LLHLX-T is lead (Pb) free with 100% matte-tin-plated leadframes.
