The AH9251 is a medium sensitivity, micropower, omnipolar Hall-effect switch designed for battery-operated handheld and industrial applications. Its chopper-stabilized architecture ensures stable magnetic switch points, while a sleep-awake logic reduces average current consumption to 8A typical at 3V. The device switches with either north or south poles and is available in TO92S and SC59 packages.
