Magnetic Sensors are electronic instruments which detect and measure the existence and strength of a magnetic field, usually within a specific range, and can be used for various applications such as navigation, guidance, and positioning.

The MLX90333LGO-BCH-100-TU is a three-axis high-precision low-field magnetic sensor from Melexis. It is designed for measuring very small magnetic fields in the range of +/-100mT, where it has a sensitivity of 0.1mT and a resolution of 0.8uT. It is a 12-pin SOIC package and operates from a 4.5V to 5.5V DC supply.

Application field

The MLX90333LGO-BCH-100-TU can be used in a wide range of applications. Examples include motor control systems, power tools, robots, and computer peripherals, just to name a few. It can also be used in aerial mapping applications for monitoring metal objects in the vicinity of the aircraft as part of navigation or obstacle avoidance systems. Additionally, it can be used to measure the orientation of the satellite antenna for telecommunications systems.

Working principle

The MLX90333LGO-BCH-100-TU works on the principle of induction. In operation, the sensor has a Hall-effect element which contains a zero-point bias magnet in order to bias the Hall-voltage. When exposed to an external magnetic field, the Hall element’s magnetic flux changes, and the output voltage is proportional to the change in flux. This output voltage is then amplified and processed to output the appropriate digital data.

The MLX90333LGO-BCH-100-TU has an integrated amplifier and digital output converter, which allows the device to measure small magnetic fields from -100mT to +100mT with a resolution of 0.1mT and a sensitivity of 0.8uT. The device also features a high-resolution digital output, with a data rate of up to 320kS/sec. With its advanced features and low-power operation, the MLX90333LGO-BCH-100-TU is perfect for applications that need to measure small magnetic fields quickly and accurately.
