Allegro MicroSystems A3280LUA is a digital Hall effect switch designed for latching operation. This device features an open-collector output capable of sourcing up to 25mA, with a supply voltage range of 4.2V to 24V and a maximum supply current of 8mA. The A3280LUA exhibits a sensing range of 4mT for trip and -4mT for release, specifically responding to the south pole magnetic field. Packaged in a 3-SIP (Supplier Device Package: 3-SIP, Package / Case: 3-SSIP) for through-hole mounting, it operates reliably across an extended temperature range of -40°C to 150°C. This component is suitable for applications in automotive, industrial, and consumer electronics requiring robust magnetic sensing and latching functionality.
