Product details
Overview
MLX90333KGO-BCH-000-RE from Melexis is a Triaxis® 3D contactless position sensor IC in TSSOP-16 package, operating from −40 °C to +125 °C, delivering 12-bit angular resolution and ratiometric analog or PWM outputs for joystick and linear stroke sensing. It measures BX, BY, and BZ magnetic field components using integrated magneto-concentrator (IMC) and Hall plate, enabling rotary, linear, and 3D position detection in automotive and industrial HMI.
For engineers reviewing the MLX90333KGO-BCH-000-RE datasheet, pinout, applications, or equivalent options, this page provides verified technical context, calibrated output behavior, dual-die redundancy architecture, thermal accuracy specs, and real-world interface constraints for robust mechanical integration.
Technical Context
The MLX90333KGO-BCH-000-RE implements a dual-die TSSOP-16 configuration with isolated signal paths for full functional redundancy, supporting independent analog/PWM outputs on OUT1/OUT2 and SPI communication via MOSI/MISO/SCLK/SS pins. Its DSP-based 16-bit RISC core executes CoRDiC transforms at 5 MIPS to compute angular position from raw VX/VY/VZ ADC data with programmable dead zone, clamping, and LNR correction.
It features two independent output stages with ±20 mA drive capability, configurable slew rate (100–200 V/ms), and diagnostic bands defined by 4% and 96% VDD thresholds. The device supports slow mode (7 MHz clock, 600 μs sampling) and fast mode (20 MHz clock, 200 μs sampling), with filter settings (0–5) adjusting step response from 4 μs to 600 ms.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Temp Range | −40 °C to +125 °C - qualified for under-hood automotive and industrial control environments |
| Output Resolution | 12-bit analog/PWM - enables 0.0879° angular step size over 360° full scale |
| Magnetic Sensing | BX/BY: 20–70 mT; BZ: 24–140 mT - supports common NdFeB and ferrite magnets at air gaps up to 5 mm |
| Supply Voltage | 4.5–5.5 V - compatible with standard 5 V microcontroller I/O rails and regulator outputs |

Pinout & Package
TSSOP-16 package with exposed thermal pad (RoHS-compliant); dual-die architecture enables full hardware redundancy and independent signal path validation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 9 | VDIG1 / VDIG2 | Digital supply for die 1 and die 2 - decoupling required per die to maintain EMC integrity |
| 2, 10 | VSS1 / VSS2 | Ground return for die 1 and die 2 - must be connected separately to minimize crosstalk |
| 3, 11 | VDD1 / VDD2 | Analog supply for die 1 and die 2 - independent regulation recommended for noise immunity |
| 4, 14 | OUT2 / OUT22 | Second analog/PWM output channel - configurable independently for X/Y axis or dual-redundant reporting |
| 5, 15 | OUT1 / OUT12 | Primary analog/PWM output channel - default for alpha angle or linear position |
| 6, 12, 16 | Test 1 / Test 02 / Test 11 | Factory test points - unused in application; tie to VSS per EMC recommendation |
| 7, 13 | MOSI/MISO / /SS1 | SPI data and chip select for die 1 - supports daisy-chain or independent host communication |
| 8, 14 | SCLK / SCLK2 | SPI clock input for die 1 and die 2 - synchronous operation enables time-aligned diagnostics |
Key Features
| Feature | Design Value |
|---|---|

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-ABB-000-RE | Single-die TSSOP-16; SPI-only output; no analog/PWM; higher 16-bit serial resolution | Lacks dual-output flexibility and analog compatibility; requires host MCU with SPI interface | Choose when serial-only interface suffices and redundancy is not required |
| MLX90393ELH-ABA-000-SP | SOIC-8 single-die; 3-axis magnetic field digitizer (not position processor); no on-chip angle calculation | Requires external MCU to compute angle; no programmable transfer curve or diagnostics | Choose when raw B-field data is needed for custom algorithms or cost-sensitive non-safety designs |
Compared with MLX90333KGO-BCH-000-RE, the MLX90363 offers higher serial resolution but sacrifices analog/PWM versatility and redundancy, while the MLX90393 provides raw field data at lower cost but shifts all computation and safety logic to the host - making MLX90333KGO-BCH-000-RE optimal for self-contained, safety-aware HMI and actuator feedback.

FAQ
What is the operating temperature range of the MLX90333KGO-BCH-000-RE?
The MLX90333KGO-BCH-000-RE is rated for −40 °C to +125 °C ambient operation, validated per its K temperature suffix. This range supports under-hood automotive applications and industrial environments with high thermal stress. The device maintains 10-bit angular thermal accuracy across this span using on-chip EEPROM-stored calibration coefficients applied during runtime DSP processing.
Does the MLX90333KGO-BCH-000-RE support both analog and PWM outputs simultaneously?
Yes, the MLX90333KGO-BCH-000-RE supports concurrent analog and PWM outputs on OUT1 and OUT2 in its TSSOP-16 dual-die configuration. Each output channel is independently configurable via EEPROM programming for ratiometric analog, PWM (100–1000 Hz), or disabled state - enabling mixed-mode feedback such as analog X-axis + PWM Y-axis in joystick applications.
How is redundancy implemented in the MLX90333KGO-BCH-000-RE?
The MLX90333KGO-BCH-000-RE implements hardware redundancy via two physically independent silicon dice in one TSSOP-16 package, each with dedicated VDD/VSS/VDIG supplies and isolated signal paths. Inter-die isolation exceeds 4 MΩ, and outputs (OUT1/OUT2, SPI channels) operate autonomously - allowing host systems to detect discrepancies indicative of single-point failures.
Can the MLX90333KGO-BCH-000-RE be programmed after soldering to the PCB?
Yes, the MLX90333KGO-BCH-000-RE supports end-of-line programming via its VDD, VSS, and OUT pins only - no dedicated programming interface is required. Using the Melexis PTC-04 programmer, users can calibrate transfer characteristics (alpha/beta, clamping, dead zone), set diagnostics, and lock configuration EEPROM, all through the same pins used for normal operation.
What magnetic field strength is required for reliable operation of the MLX90333KGO-BCH-000-RE?
The MLX90333KGO-BCH-000-RE requires minimum magnetic flux densities of 20 mT for BX/BY (horizontal) and 24 mT for BZ (vertical) components. Typical operation uses 40–70 mT NdFeB magnets at 2–4 mm air gaps. Field thresholds are programmable (FIELDTHRES_LOW/HIGH), and automatic gain control adapts to amplitude variations caused by vibration or temperature drift.
