The Allegro MicroSystems A1146LUA-T is a unipolar Hall effect switch designed for automotive applications. This digital switch, housed in a 3-SIP package, operates as a current source output and requires a supply voltage ranging from 3.5V to 24V, with a maximum supply current of 17mA. It features a typical sensing range of 6mT for trip and 1mT for release, with sensitivity optimized for South pole activation. Qualified to AEC-Q100 standards, this component is suitable for demanding environments, operating across an industrial temperature range of -40°C to 150°C. Its through-hole mounting type facilitates integration into various circuit designs. This device is commonly employed in automotive systems such as seat positioning, trunk latch detection, and convertible roof positioning.
