Abstract: In one implementation, a magnetic sensor device used for sensing a static or dynamic magnetic field includes a ring-shaped magnet, a sensor chip arranged in an opening of the ring-shaped magnet, and a leadframe, with the ring-shaped magnet and the sensor chip directly disposed on the leadframe. The sensor chip may further include a carrier with a stepwise configuration having two or more different planes with the ring-shaped magnet and the sensor chip disposed on different planes.
