Product details
Overview
MLX90333KDC-BCH-100-TU from Melexis is a Triaxis® 3D contactless position sensor IC in SOIC-8 package, delivering 12-bit angular resolution, programmable analog/PWM/serial output modes, and ±40 mT to ±70 mT magnetic field sensing range for BX/BY components. It supports joystick, linear stroke, and rotary position sensing with end-of-line calibration of transfer characteristics.
For engineers reviewing the MLX90333KDC-BCH-100-TU datasheet, pinout, applications, or equivalent options, this page details its Triaxis® Hall-based 3D magnetic vector processing, dual-output capability in joystick mode, SPI interface support (BCH-100 variant), and automotive-grade -40°C to +125°C operation.
Technical Context
The MLX90333KDC-BCH-100-TU integrates an IMC for BX/BY sensing and conventional Hall plate for BZ detection, enabling full 3D magnetic flux vector (BX, BY, BZ) measurement and digital signal processing via a 16-bit RISC microcontroller. Its DSP computes angular position using CoRDiC algorithms and supports two independent outputs (OUT1/OUT2) with configurable transfer characteristics.
This variant implements SPI serial protocol mode (enabled by BCH-100 option code), featuring MOSI/MISO/SCLK/SS pins on SOIC-8, and includes EEPROM-based programmability for offset, gain, clamping, dead zone, and filtering-calibrated via PTC-04 unit using only VDD/VSS/OUT terminals.

FAQ
What output interfaces does the MLX90333KDC-BCH-100-TU support?
The MLX90333KDC-BCH-100-TU supports three output modes: ratiometric analog voltage, PWM signal, and 3-wire SPI serial protocol. The BCH-100 option code confirms SPI functionality is enabled, with dedicated MOSI/MISO/SCLK/SS pins mapped to SOIC-8 pins 5, 4, 6, and 3 respectively per datasheet Rev. 008 Section 4. This allows host MCU readout of 16-bit position data and real-time parameter access.
How is the MLX90333KDC-BCH-100-TU calibrated for custom transfer characteristics?
Calibration of the MLX90333KDC-BCH-100-TU is performed end-of-line using Melexis' PTC-04 programming unit, which communicates exclusively through VDD, VSS, and OUT pins-no additional debug interface required. Parameters including Alpha/Beta discontinuity points, clamping levels, dead zones, and filtering coefficients are written to on-chip EEPROM, enabling precise matching to mechanical tolerances and thermal drift compensation.
What is the magnetic sensing architecture of the MLX90333KDC-BCH-100-TU?
The MLX90333KDC-BCH-100-TU employs Triaxis® technology: horizontal magnetic components (BX, BY) are sensed via an Integrated Magneto-Concentrator (IMC), while the vertical component (BZ) is measured using a conventional Hall plate. This dual-path architecture enables true 3D vector measurement with 20–70 mT BX/BY sensitivity and 24–140 mT BZ range, all processed by an on-chip 16-bit RISC DSP.
Does the MLX90333KDC-BCH-100-TU support dual-output operation for joystick applications?
Yes, the MLX90333KDC-BCH-100-TU supports dual independent outputs (OUT1 and OUT2) configured for simultaneous X- and Y-axis reporting in joystick mode. Each output can be individually set to analog, PWM, or SPI function via EEPROM programming, enabling true 2D position tracking with programmable cross-axis coupling and thermal drift compensation-critical for precision HMI devices.
What is the operating temperature range and qualification grade of the MLX90333KDC-BCH-100-TU?
The MLX90333KDC-BCH-100-TU is qualified for -40°C to +125°C ambient operation (K-grade), verified per AEC-Q100 stress testing. This makes it suitable for under-hood automotive applications, industrial motor controls, and medical equipment exposed to wide thermal excursions-without derating, and with guaranteed 10-bit angular thermal accuracy across the full range.
