Allegro MicroSystems A3281LLHLT is a Hall Effect digital switch latch with an open collector output, packaged in a SOT-23W. This device is designed for precise magnetic sensing applications, featuring a latching function that requires a reversal of the magnetic pole to change state. The A3281LLHLT exhibits a sensing range of 9mT trip and -9mT release, ensuring robust operation. It operates within a supply voltage range of 4.2V to 24V, with a maximum supply current of 8mA and a maximum output current of 25mA. The device's surface mount configuration and SOT-23W package are ideal for high-density board designs. This component is commonly utilized in automotive, industrial, and consumer electronics for position sensing and speed detection. It is supplied in a Tape & Reel (TR) package for efficient automated assembly. The operating temperature range is -40°C to 150°C.
