Product details
Overview
MLX90333KDC-BCH-000-RE from Melexis is a Triaxis® 3D contactless position sensor IC in SOIC-8 package, delivering 12-bit angular resolution, ratiometric analog or PWM output, and programmable transfer characteristics (Alpha/Beta) for rotary, linear, and joystick motion sensing. It operates from -40°C to +125°C and integrates IMC-based BX/BY sensing with conventional Hall BZ detection.
For engineers reviewing the MLX90333KDC-BCH-000-RE datasheet, pinout, applications, or equivalent options, this page provides verified technical context, calibrated output behavior, magnetic field sensitivity (BX/BY: 20–70 mT, BZ: 24–140 mT), thermal accuracy (10-bit angular), and end-of-line programmability via PTC-04.
Technical Context
The MLX90333KDC-BCH-000-RE implements Triaxis® technology using an integrated magneto-concentrator (IMC) for horizontal field (BX/BY) detection and a conventional Hall plate for vertical field (BZ) measurement. Its on-chip DSP computes angular position from raw 15-bit ADC data (slow mode) or 14-bit ADC data (fast mode), supporting both single-angle (Alpha) and dual-angle (Alpha/Beta) output modes.
This variant uses a single die in SOIC-8, supports analog/PWM output only (no SPI), and features programmable clamping, dead zone, linearity correction, and thermal drift compensation. Output transfer characteristics are calibrated end-of-line using the PTC-04 programmer via VDD/VSS/OUT pins-no dedicated programming interface required.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 3D magnetic position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90363KDC-ABB-000-RE | Same SOIC-8 package, but includes SPI interface and enhanced diagnostics; higher EEPROM capacity (256 B vs. 128 B) | Required where host MCU needs digital position readback or firmware-updatable calibration data | Select when serial protocol integration or field recalibration capability is needed; not drop-in due to pinout and protocol differences |
| AS5055A-DSOM | 12-bit magnetic rotary encoder in TSSOP-16; supports SPI/I²C; no analog/PWM output; lower temp grade (-40°C to +125°C) | Suitable for pure digital position readout; lacks dual-output joystick mode and programmable analog transfer curve | Choose for cost-sensitive digital-only systems where analog output and end-of-line calibration are unnecessary |
Compared with MLX90333KDC-BCH-000-RE, the MLX90363 offers SPI flexibility at the cost of added complexity and non-pin-compatible layout, while the AS5055A trades analog/PWM versatility and Triaxis® 3D programmability for simpler digital interfacing and lower unit cost.

FAQ
What output modes does the MLX90333KDC-BCH-000-RE support?
The MLX90333KDC-BCH-000-RE supports ratiometric analog voltage and PWM output modes only-it does not include SPI functionality (that variant is MLX90333KDC-BCT-000-RE). Both OUT1 and OUT2 can be independently configured for analog or PWM, enabling dual-axis joystick operation with programmable Alpha/Beta transfer curves calibrated via PTC-04 using VDD/VSS/OUT pins.
What is the maximum magnetic field the MLX90333KDC-BCH-000-RE can measure?
The MLX90333KDC-BCH-000-RE measures magnetic flux density up to ±4 T absolute maximum, but its specified linear operating range is BX/BY: 20–70 mT and BZ: 24–140 mT. Above 70 mT, the integrated magneto-concentrator (IMC) begins saturating, increasing linearity error-so practical magnet selection targets ≤70 mT for optimal accuracy in XY plane sensing.
How is the MLX90333KDC-BCH-000-RE calibrated during production?
The MLX90333KDC-BCH-000-RE undergoes end-of-line calibration using Melexis' PTC-04 programming unit, which communicates exclusively through the VDD, VSS, and OUT pins-no dedicated programming interface is required. Calibration configures Alpha/Beta transfer parameters (offset, gain, clamping, dead zone), thermal drift compensation, and output mode, storing settings in on-chip 128 B EEPROM for permanent retention.
Does the MLX90333KDC-BCH-000-RE support functional safety standards?
Yes-the MLX90333KDC-BCH-000-RE includes integrated diagnostics such as broken VDD/VSS detection, output short-circuit monitoring, and active diagnostic band signaling on OUT1/OUT2. These features support ASIL-B compliance in automotive applications when implemented per ISO 26262 guidelines, and its -40°C to +125°C qualification aligns with AEC-Q100 Grade 0 requirements.
What package and pin count does the MLX90333KDC-BCH-000-RE use?
The MLX90333KDC-BCH-000-RE uses a RoHS-compliant SOIC-8 package (5.3 mm × 6.2 mm × 1.75 mm) with 8 leads. Pin 1 is marked with a dot; pins 2 and 6 are test pads (recommended tied to VSS), pin 3 is unused (must connect to VSS), and pins 4–5 provide dual analog/PWM outputs. This single-die configuration differs from the dual-die TSSOP-16 variants (e.g., GO package codes).
