Allegro MicroSystems A1227LLTTK-T is a Hall effect latching digital switch with an open-drain output. This device features temperature compensation, ensuring consistent performance across its operating temperature range of -40°C to 150°C. Designed for surface mounting in the SOT-89-3 package, the A1227LLTTK-T is suitable for applications requiring robust magnetic sensing capabilities. Its latching functionality requires a south pole magnetic field to switch its output state, with a trip and release point of 5mT. The device operates with a supply voltage range of 3.8V to 24V and has a maximum output current of 25mA and a maximum supply current of 6mA. This component finds application in various industries, including automotive, industrial automation, and consumer electronics, for position sensing and speed detection.
