The A1227LLHLT-T is a Hall-effect latch designed for high-temperature operation up to 150°C, with a 3-pin SOT-23W surface-mount package. It operates from a 3.8 V to 24 V unregulated supply and features an open-drain output capable of sinking 25 mA. The device includes reverse battery protection, 40 V load dump compliance, and 8 kV HBM ESD protection without external components. Magnetic switchpoints are symmetric and temperature-stable, with a operate point of 175 G and release point of −175 G. It is classified as not for new design with no samples available.
