Current transducers, also known as current sensors, are electronic devices designed to measure current in a circuit and generate a corresponding voltage signal for further processing. This article introduces MLX91206LDC-CAH-104-SP, a current transducer developed by Melexis, and discusses its application field and working principle.

MLX91206LDC-CAH-104-SP is a high performance, integrated device for measuring AC/DC current. It features a high linearity and low temperature coefficient, making it ideal for accurate, high bandwidth current measurements. The transducer consists of a Hall-Effect sensor integrated with a chopper amplifier and a microcontroller, and has a wide operating temperature range from -40°C to +125°C.

The MLX91206 current transducer is widely used in electric motor and generator control, motor control, load control, and current monitoring applications. It is suitable for applications in automotive, industrial and HVAC systems, and in process control, energy metering, and electric vehicle charging systems. In addition, the transducer can be used to measure both AC and DC current in high voltage systems, including solar and wind turbine applications.

The MLX91206LDC-CAH-104-SP current transducer works by converting the physical quantity of current to a proportional voltage output. The output is generated by the Hall-Effect sensor, which measures the difference in magnetic field strength between the current-carrying line and the return line. The amplitude of the output voltage is proportional to the strength of the magnetic field, which is in turn proportional to the current flowing in the line. Meanwhile, the chopper amplifier and microcontroller process the output voltage and ensure that the output is in a stable digital form.

In conclusion, the MLX91206LDC-CAH-104-SP current transducer is a highly reliable device which can be used to accurately measure AC and DC current in a range of industrial, automotive, and energy applications. The transducer works by converting the current to a proportional voltage output, which is then processed by a chopper amplifier and microcontroller for further analysis. This makes the MLX91206 an ideal solution for accurately monitoring current in a range of applications.
