Allegro MicroSystems Inc. Continuous-Time Switch Unipolar Switch A1106LLHLX-T

The A1106LLHLX-T is a continuous-time Hall-effect switch designed for automotive and industrial motor commutation applications. It features a 3-pin SOT23W surface-mount package and operates from a supply voltage of 3.8 to 24 V with an absolute maximum voltage rating of ±30 V. The device is AEC-Q100 automotive qualified and supports ambient temperatures from -40°C to 150°C. It includes integrated voltage regulation, reverse battery protection, and robust EMC and ESD performance. The output has a saturation voltage of 215 to 400 mV at 20 mA sink current and a power-on time of up to 4 μs. The switch point is optimized for magnetic flux densities ranging from 160 G to 430 G, and it requires no external bypass capacitor for regulator stability.
