Manufacturer: Allegro MicroSystems

Categories: Switches (Solid State)

Quality Control: Learn More

Allegro MicroSystems A1225LLTTK-T is a digital Hall effect latch sensor designed for precise magnetic field detection. This component, housed in a SOT-89-3 package, features an open-drain output with a maximum output current of 25mA and a maximum supply current of 6mA. The device operates from a 3.8V to 24V supply voltage and offers temperature compensation for reliable performance across its operating temperature range of -40°C to 150°C. Its latching function requires a south pole magnetic field for activation, with a trip point of 17.5mT and a release point of -17.5mT. The A1225LLTTK-T is commonly utilized in automotive applications, industrial controls, and consumer electronics requiring robust position sensing and speed detection. It is supplied on tape and reel.
