Working Principle

The MLX90215EVA-AAA-106-BU is an integrated, high-sensitivity Hall effect linear and compass IC. This device measures the magnetic field along the X-axis and is based on a special CMOS (Complementary Metal Oxide Semiconductor) process. The device contains an internal, temperature compensated, bi-directional cmos Hall effect sensing cell and signal conditioning circuitry that is designed to deliver a high-precision 10-bit resolution (14-bit optional) output signal.

The Hall effect portion of the device is generated by the current flow through the sensing cell relative to the current through the reference cell. This produces an output signal that represents the linear (X) or rotary (Y) component of the applied magnetic field. The magnetic sensitivity is adjustable to suit each application requirement. The integrated signal conditioning and control circuitry routes the Hall effect output signal to the output pins.

The MLX90215EVA-AAA-106-BU is programmable via an I2C interface. This allows for easy configuration of the sensor’s parameters such as sensitivity, resolution, maximum measureable range and temperature compensation. Additionally, the device offers on-chip shielding which reduces noise sensitivity and immunity to RF interference, and is capable of detecting multiple magnetic field directions and de-bounce times.

Conclusion

The MLX90215EVA-AAA-106-BU is an advanced magnetic sensor for linear and compass applications. Its wide range of applications and features, such as a resolution of 12 or 14 bits, a full scale magnetic range of ±11 mT, low power consumption, temperature compensation, and on-chip shielding, make it an attractive choice for many applications. Additionally, its easy programmability through an I2C interface complements its modern specifications, making this device an excellent choice for various motor control, robotics, navigation, security, and consumer applications.
