MLX91205   Current Sensor

The new Triaxis™ current sensor MLX91205 is a single axis integrated magnetic sensor based on the Hall effect. It produces an analog, ratio-metric output voltages proportional to the applied magnetic field parallel with the chip surface.
The circuit is fabricated using a standard CMOS process. The additional ferromagnetic layer (Triaxis™ or IMC™=Integrated Magnetic Concentrator) that is added in a simple post-processing step, amplifies the magnetic field and concentrates it on the Hall elements. Therefore, the circuit features very high magnetic sensitivity, low offset and low noise.
The MLX91205 is ideally suited for current sensing in automotive and industrial environments. Two different versions with different magnetic ranges are available.
