The A1214LLHLX-T is a continuous-time Hall-effect latch in a 3-pin SOT23W surface-mount package, designed for automotive and industrial motor commutation. It operates from 3.8 to 24 V with a ±30 V absolute maximum supply voltage rating and functions over an ambient temperature range of -40°C to 150°C. The device includes integrated voltage regulation, reverse-battery protection, and high ESD and EMC robustness. It features a magnetic switch point range of -300 G to 300 G and an NMOS open-drain output capable of sourcing up to 25 mA. The part is AEC-Q100 automotive qualified and manufactured using BiCMOS technology for low noise and stable performance across temperature extremes.
The A121x family provides reliable and efficient latching functionality for a variety of applications. These continuous-time devices offer fast power-on time, low-noise operation, and integrated protection features. Factory programming ensures accurate switchpoint thresholds.
