The A1205LLHLT-T is a continuous-time bipolar Hall-effect switch designed for automotive and industrial applications, including power closures, motor commutation, and fan control. It is housed in a 3-pin SOT23W surface-mount package and operates from a supply voltage of 3.8 to 24 V, with an absolute maximum supply voltage rating of 30 V. The device includes integrated reverse battery protection and regulator stability without a bypass capacitor. It is AEC-Q100 automotive qualified and operates over an ambient temperature range of -40°C to 150°C. Magnetic switch points are specified at -50 G to 50 G. The output is an NMOS transistor capable of sinking up to 25 mA. The part is RoHS compliant and features high ESD ratings and robust EMC performance.
