The A1152LLHLX-T is a two-wire, unipolar Hall-effect switch with chopper stabilization for low switchpoint drift across temperature. It operates from 3 to 24 V, supports an ambient temperature range of -40°C to 150°C, and is AEC-Q100 automotive qualified. The device is housed in a 3-pin SOT23-W surface-mount package measuring 2 mm × 3 mm × 1 mm. It includes on-chip protection against supply transients, reverse battery connection, and has integrated voltage regulation. The output supply current ranges from 2 to 5 mA at the south pole magnetic operate point.
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.
