The A1213LLHLX-T is a continuous-time Hall-effect latch designed for automotive and industrial motor commutation, operating from 3.8 to 24 V with a ±30 V absolute maximum supply voltage rating. It features reverse-battery protection, high ESD tolerance, and regulator stability without a bypass capacitor. The device is AEC-Q100 qualified and operates over an ambient temperature range of -40°C to 150°C. It is packaged in a 3-pin SOT23W surface-mount configuration with a magnetic switch point range of -200 G to 200 G. Factory-programmed for optimized switch point accuracy, it includes an integrated voltage regulator, Hall-voltage generator, small-signal amplifier, Schmitt trigger, and NMOS output transistor on a single chip.
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.
