The A1123ELHLT-T is a chopper-stabilized precision Hall-effect switch designed for automotive and industrial applications, featuring a 3-pin SOT23W surface-mount package (suffix LH). It operates from an unregulated supply voltage of 3 to 24 V and includes output short-circuit protection and reverse-battery protection. The device is AEC-Q100 automotive qualified with an operating ambient temperature range of -40 to 150°C. It has a south pole operate point of 280 G and a release point of 225 G, with an open-drain output capable of sinking up to 25 mA. The package is lead-free with a matte-tin-plated leadframe.
