Allegro MicroSystems A1227LLTTR-T is a digital Hall effect latch sensor packaged in a SOT-89-3 (TO-243AA) surface-mount configuration. This device operates with a supply voltage range of 3.8V to 24V and a maximum supply current of 6mA. The output is open drain, capable of sinking up to 25mA. The A1227LLTTR-T features a latching function, requiring opposite magnetic poles to switch states, and is specifically sensitive to the south pole. Its sensing range is characterized by a 17.5mT trip and -17.5mT release threshold. This component is designed for operation across an extended temperature range of -40°C to 150°C. It is commonly employed in automotive and industrial applications requiring precise magnetic position sensing.
