The Melexis MLX90393 is the newest Addition to the Melexis Position sensing Portfolio, bringing the highest flexibility in the portfolio's smallest assembly. Complementing this, the magnetic field sensor is designed for micropower applications, with programmable duty cycles in the range of 0.1% to 100%.
The MLX90393 magnetic field sensor can be reprogrammed to different modes and with differnet Settings at runtime. The sensor offers a 16-bit Output propotional to the magnetic flux density sensed along the XYZ axes using the Melexis proprietary Triaxis® Technology and also offers a temperature output signal. The output signals (raw X, Y, Z Magnetic data and Temperature data) will be provided through the I2C fast mode protocol, or via half-duplex SPI (3- or 4-wire). There is an on-board non volatile memory to store calibration data on-chip. By selecting which axes are to be measured, the raw data can be used as input for further post-processing, such as for joystick applications, rotary knobs, and more complex 3D position sensing applications. Unparalleled performance is achieved with this sensor, which is primarily targeting industrial and consumer applications.

Features Application examples
  • Magnetometer Sensor (Absolute Linear & Rotary, 3D-Joystick)
  • Micropower Triaxis® Hall Technology
  • Operating voltage from 2.2V to 3.6V 
  • Stand by current < 60µA
  • 16-pin Quad Flat No-Lead 16L QFN 3x3
  • IN-application runtime programmable functional parameters
  • Trade-off between current consumption,
    Speed and Signal noise with best-in-class Figure of Merit
  • Can be used to measure magnetic XYZ
    and temperature T or any combination thereof
  • Duty cycle between 0,1% and 100% (continuous burst)
  • Single measurement mode,
    burst mode and wake-up on Change mode
  • SPI slave and/or I2C slave with 2 bits
  • HW adressing and 5 bits SW
  • For certain Encoder applications Speed is crucial,
    which is possible by increasing the duty cycle to 100%
    (i.e. Maximum current consumption) and
    minimizing the conversion time
    (i.e. higher data rate at the expense
    of more noise on the Signal).
  • Other battery powered applications that only
    require occasional sensor readout can opt for a
    different trade-off: reduced duty cycle
    (lower current consumption) and an average
    conversation time for reduced noise
  • Human-Machine Interface (HMI):
    • Joystick w/Push
    • Rotary knob w/Push
    • Lever / slide Switch linear stroke
  • Automotive applications
  • Robotics & factory automation
  • Home and building automation
  • Flow meter (Metering)
