The A1203LLHLT-T is a continuous-time bipolar Hall-effect switch designed for automotive and motor commutation applications. It features a 3-pin SOT23W surface-mount package, operates from a 3.8 V to 24 V supply, and is AEC-Q100 automotive qualified. The device has a south-pole operate point of 95 G and a release point of -95 G, with a hysteresis of 52 G. It includes integrated voltage regulation, reverse-battery protection, and output short-circuit protection without requiring external components. The power-on time is up to 4 μs, with an output saturation voltage of up to 400 mV at 20 mA. The operating ambient temperature range is -40°C to 150°C.
The A1202/3 family provides fast power-on time and low-noise operation for a variety of applications. These continuous-time bipolar switches offer robust performance, a wide operating voltage range (3.8V-24V), and integrated protection features. Factory programming ensures accurate switchpoint thresholds.
