The A1120LLHLX-T is a chopper-stabilized precision Hall-effect switch designed for automotive applications, operating from an unregulated supply voltage of 3 to 24 V. It features a south-pole responsive unipolar switch with a magnetic operate point of 280 G and release point of 225 G, and includes output short-circuit protection and reverse-battery protection. Packaged in a 3-pin SOT23W surface-mount (LH) style, it is rated for ambient temperatures from -40°C to 150°C and meets AEC-Q100 automotive qualification. The device supports up to 25 mA output sink current and is built with a chopper-stabilized design for enhanced temperature stability and stress resistance.
