Allegro A1391/A1392 handbook

A1391-DS is the datasheet of A1391 and A1392, it is a micro power 3V linear hall effect sensor with tri-state output and user-selectable sleep mode. This integrated circuit (IC) provides a voltage output that is directly proportional to an applied magnetic field. In many applications, it is difficult to achieve sufficient sensitivity levels with a Hall effect sensor IC without consuming more than 3 mA of current. The A1391 and A1392 minimize current consumption to less than 25 μA through the addition of a user-selectable sleep mode.
