Product details
Overview
MLX90333KDC-BCT-000-SP 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 joystick and linear stroke sensing. It measures BX, BY, BZ magnetic field components using integrated magneto-concentrator (IMC) and Hall plate, operating from −40 °C to +125 °C.
For engineers reviewing the MLX90333KDC-BCT-000-SP datasheet, pinout, applications, or equivalent options, this page delivers verified technical context, calibrated output behavior, magnetic sensitivity specs, thermal accuracy data, and SOIC-8 pin mapping - all confirmed against Melexis Revision 008 datasheet and ordering information.
Technical Context
The MLX90333KDC-BCT-000-SP integrates a 16-bit RISC microcontroller (5 MIPS @ 20 MHz), 128 B EEPROM, and dual-path signal processing: IMC-enhanced BX/BY sensing and direct BZ Hall measurement. Its DSP computes angular position via CoRDiC transformation with programmable dead zone, clamping, and LNR correction.
It supports three output modes - ratiometric analog, PWM (100–1000 Hz), and SPI serial protocol - with independent OUT1/OUT2 channels. The "BCT" option code confirms SPI capability, and the "K" temperature grade enables operation up to +125 °C with ±60 LSB15 thermal offset drift on raw signals.

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 |
|---|---|---|---|
| MLX90363KGO-ABD-000-RE | Dual-die TSSOP-16 package with full redundancy; higher current draw (2× IDD); includes isolated diagnostics | Required for ASIL-D systems needing hardware redundancy; not pin-compatible with SOIC-8 MLX90333KDC-BCT-000-SP | Select when functional safety certification (ISO 26262) mandates dual-channel fault tolerance. |
| AMS AS5055A-BQFT | Single-die 14-bit angle sensor; SPI-only interface; no analog/PWM outputs; lower max temp (105 °C) | Suitable for compact SPI-based encoders but lacks dual-output flexibility and extended temperature range of MLX90333KDC-BCT-000-SP | Choose for space-constrained designs where SPI integration suffices and thermal margin is less critical. |
Compared with MLX90333KDC-BCT-000-SP, the MLX90363KGO-ABD-000-RE adds hardware redundancy at cost of layout area and power, while the AMS AS5055A-BQFT trades output flexibility and temperature rating for higher raw resolution and smaller footprint - making MLX90333KDC-BCT-000-SP optimal for dual-output, wide-temp, mixed-interface HMI and motion control.

FAQ
What output modes does the MLX90333KDC-BCT-000-SP support?
The MLX90333KDC-BCT-000-SP supports three configurable output modes: ratiometric analog voltage, PWM (100–1000 Hz), and 3-wire SPI serial protocol. Mode selection is stored in EEPROM and programmed via Melexis PTC-04 using only VDD, VSS, and OUT pins - no dedicated programming interface required. Each output (OUT1/OUT2) can be independently assigned.
How is the MLX90333KDC-BCT-000-SP calibrated for custom transfer characteristics?
The MLX90333KDC-BCT-000-SP is calibrated end-of-line using Melexis' PTC-04 programming unit, which communicates exclusively through VDD, VSS, and OUT pins. Users configure Alpha/Beta parameters, clamping levels, dead zones, and filtering coefficients directly into EEPROM - enabling precise linearization, thermal drift compensation, and application-specific response curves without modifying hardware.
What is the magnetic field range supported by the MLX90333KDC-BCT-000-SP?
The MLX90333KDC-BCT-000-SP senses BX/BY fields from 20 mT to 70 mT and BZ fields from 24 mT to 140 mT. The integrated magneto-concentrator (IMC) enhances sensitivity for horizontal components, while the vertical Hall plate handles BZ detection. Field saturation begins above 70 mT for BX/BY, limiting usable linear range in high-field configurations.
Does the MLX90333KDC-BCT-000-SP include built-in diagnostics?
Yes, the MLX90333KDC-BCT-000-SP features comprehensive self-diagnostics including broken-VSS/VDD detection, output short-circuit monitoring, and configurable diagnostic bands. Diagnostic status is reported via dedicated output levels (e.g., BVSSPD at 4% VDD) and programmable flags in SPI register space - reducing need for external monitoring circuitry in safety-critical designs.
What is the significance of the "BCT" option code in MLX90333KDC-BCT-000-SP?
The "BCT" option code in MLX90333KDC-BCT-000-SP explicitly denotes SPI serial protocol capability, distinguishing it from "BCH" (analog/PWM-only) variants. This enables bidirectional communication with a host controller for real-time parameter readback, dynamic reconfiguration, and diagnostic data retrieval - essential for adaptive HMI and closed-loop motion control systems.
