The A1150LLHLX-T is a two-wire, unipolar Hall-effect switch for automotive applications, packaged in a 3-pin SOT23-W surface-mount format measuring 2 mm × 3 mm × 1 mm. It operates from 3 to 24 V, supports an ambient temperature range of -40°C to 150°C, and is AEC-Q100 qualified. The device features chopper stabilization for low switchpoint drift, on-chip supply transient and reverse-battery protection, and integrated voltage regulation. Magnetic operate point ranges from 2 to 5 G for the south polarity variant.
The A115x family provides a cost-effective solution for two-wire Hall-effect switching, with chopper stabilization for enhanced temperature stability and a variety of package options for design flexibility.
