Absolute 3D Position Sensor
Simple & Robust Magnetic Design
Tria⊗is® Hall Technology
Programmable Linear Transfer Characteristics
(Alpha, Beta)
The MLX90333 is a Tria⊗is® Position Sensor able
to sense any magnet moving in its surrounding
through the measurement and the processing of
the 3 spatial components of the magnetic flux
density vector (i.e. BX, BY and BZ).
The horizontal components (BX and BY) are sensed
thanks to an Integrated Magneto-Concentrator
(IMC) while the vertical component (BZ) is sensed
through conventional Hall plate.

Selectable Analog (Ratiometric), PWM, Serial
Protocol
12 bit Angular Resolution - 10 bit Angular
Thermal Accuracy
The MLX90333 features a contactless position
sensor mode suitable for rotary position sensor
(through-shaft magnet), linear stroke position
sensor (magnet displacement parallel to the
device surface) and for 3D/"Joystick" position
sensor.

40 bit ID Number
Single Die – SOIC-8 Package RoHS Compliant
Dual Die (Full Redundant) – TSSOP-16 Package
RoHS Compliant
The processed position information is ultimately
reported as a ratiometric analog output or as
PWM (Pulse-Width Modulation) signal. In case of
SOIC-8
TSSOP-16
3D/"Joystick" mode, the device features
2
independent outputs. A 3-pin SPI (serial interface)
mode is also available to transfer the position
information to a host-controller.

Linear Position Sensor
The output transfer characteristic is fully
programmable (e.g. offset, gain, clamping levels,
linearity, thermal drift, filtering, range...) to match
any specific requirement through end-of-line
calibration. The Melexis programming unit PTC-04
communicates and calibrates the device
exclusively through the connector terminals (VDD-
VSS-OUT).
