Allegro MicroSystems A1212EUA-T is a digital Hall effect switch, functioning as a latching sensor. This component utilizes Hall effect technology to detect magnetic field polarity, specifically responding to the south pole for activation. It features an open-drain output type, capable of sourcing up to 25mA, with a supply current of 7.5mA maximum. The device operates within a voltage supply range of 3.8V to 24V and is qualified for use across an industrial temperature range of -40°C to 85°C. Key specifications include a typical trip magnetic flux density of 17mT and a release flux density of -17mT. The A1212EUA-T is supplied in a 3-SIP (Single In-line Package) for through-hole mounting. This device is commonly found in applications such as automotive systems, industrial automation, and consumer electronics requiring reliable magnetic sensing and latching functionality.
