The A1121LLHLT-T is a chopper-stabilized precision Hall-effect switch designed for automotive applications with extended temperature stability up to 150°C. It operates from an unregulated supply of 3 to 24 V and features an open-drain output capable of sinking up to 25 mA with short-circuit protection. The device is AEC-Q100 automotive qualified and includes reverse-battery and overvoltage protection. It is housed in a 3-pin SOT23W surface-mount package (suffix LH) and provides a unipolar switching response with a magnetic operate point of 70 G and release point of 95 G for south pole excitation.
