Product details
Overview
MLX90333EGO-BCT-000-TU from Melexis is a Triaxis® 3D contactless position sensor IC in TSSOP-16 package, featuring dual-die redundancy, 12-bit angular resolution, ratiometric analog/PWM/serial output modes, and programmable transfer characteristics for joystick, linear stroke, and rotary sensing applications.
For engineers reviewing the MLX90333EGO-BCT-000-TU datasheet, pinout, applications, or equivalent options, this page delivers verified technical context, calibrated accuracy specs, dual-die isolation data, SPI interface timing, and end-user programmable parameters including Alpha/Beta discontinuity points and clamping levels.
Technical Context
The MLX90333EGO-BCT-000-TU integrates two independent silicon dies in one TSSOP-16 package, enabling full hardware redundancy with 4 MΩ inter-die isolation resistance. It measures all three magnetic field components (BX, BY, BZ) using an integrated magneto-concentrator (IMC) for horizontal sensing and conventional Hall plates for vertical (BZ) detection.
Its digital signal processor computes angular position via CoRDiC-based rectangular-to-polar conversion, supports 16-bit serial protocol output with MOSI/MISO/SCLK/SS pins, and allows real-time calibration of gain, offset, dead zone, clamping, and thermal drift compensation through EEPROM-programmable LNR and FILTER parameters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Modes | Ratiometric analog, PWM (100–1000 Hz), or 3-wire SPI serial protocol |
| Angular Resolution | 12-bit (0.088°/LSB theoretical), with 10-bit thermal accuracy over -40°C to +150°C |
| Magnetic Sensing Range | BX/BY: 20–70 mT; BZ: 24–140 mT; ±4 T absolute max flux density |
| Supply Voltage | 4.5–5.5 V; POR at 2.7 V; reverse voltage protection to -10 V |
| Sampling Rate | 600–1000 μs (slow/fast mode); step response time 4 μs (fast, filter=0) to 600 ms (slow, filter=5) |
| Isolation Resistance | 4 MΩ between dual dice - enables ASIL-D functional safety compliance |
| Programmable ID | 40-bit unique identifier stored in EEPROM for traceability and calibration binding |
Pinout & Package
TSSOP-16 package with dual-die architecture, RoHS compliant, 4.4 mm × 5.0 mm footprint, 1.2 mm height, and exposed thermal pad (not electrically connected).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 9, 11 | VDIG1 / VDIG2 / VDD2 | Digital supply rails for die 1 and die 2 - decoupling required per die |
| 2, 10, 16 | VSS1 / VSS2 / Test 11 | Ground terminals for each die and test access - unused pins must be grounded for EMC |
| 4, 6, 12, 14 | Test 01 / Test 1 / Test 02 / OUT21 | Factory test points and secondary output - OUT21 is active in dual-output 3D mode |
| 5, 7, 15 | MOSI/MISO / OUT12 / MOSI1/MISO1 | SPI data I/O for both dies - supports independent host communication per die |
| 3, 13 | VDD1 / /SS1 | Main analog/digital supply and slave select for die 1 - /SS1 enables selective die addressing |
| 8 | VSS (Ground) | Primary ground reference shared across both dice - critical for noise immunity |
Key Features
| Feature | Design Value |
|---|---|
| Dual-die redundancy | Independent sensing and processing paths with 4 MΩ isolation - meets ISO 26262 ASIL-D requirements |
| Triaxis® 3D sensing | Simultaneous BX, BY, BZ measurement using IMC + Hall plate - enables true 3D joystick and linear+rotary motion capture |
| End-of-line programmability | EEPROM-stored Alpha/Beta transfer curves, clamping, dead zone, and thermal drift compensation - eliminates post-solder calibration fixtures |
| Multi-protocol output | Configurable ratiometric analog (0–100% VDD), PWM (100–1000 Hz), or SPI (16-bit angle + diagnostics) - simplifies host MCU interface selection |
| Self-diagnostic capability | Broken VDD/VSS detection, output short-circuit monitoring, and diagnostic band reporting - reduces need for external watchdog circuitry |

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-ABA-000-TU | Single-die TSSOP-16, higher 16-bit angular resolution, no dual-die redundancy, same Triaxis® front-end | Lacks hardware redundancy; suitable for ASIL-B/C systems where cost outweighs fault tolerance | Select when absolute maximum angular precision (0.005°/LSB) is prioritized over functional safety certification. |
| AS5055A-DSOT | Single-axis Hall-based encoder IC, SOIC-8, 12-bit resolution, no BZ sensing or IMC, SPI-only output | Cannot perform 3D or joystick sensing; limited to rotary or linear single-axis use cases | Choose only for cost-sensitive, non-redundant rotary applications lacking multi-axis or safety requirements. |
Compared with MLX90333EGO-BCT-000-TU, the MLX90363 offers superior resolution but no redundancy, while the AS5055A lacks 3D capability and thermal accuracy - making MLX90333EGO-BCT-000-TU uniquely suited for dual-die, high-temperature, multi-axis safety-critical designs.

FAQ
What is the operating temperature range of the MLX90333EGO-BCT-000-TU?
The MLX90333EGO-BCT-000-TU operates from -40°C to +150°C, validated per its 'L' temperature suffix and confirmed in the Absolute Maximum Ratings table. This extended range supports under-hood automotive applications and industrial environments where thermal cycling exceeds standard commercial limits. The device maintains 10-bit angular thermal accuracy across this full span, with offset drift specified at ±90 LSB15 for raw signals and ±0.4%VDD for DAC/output stage.
Does the MLX90333EGO-BCT-000-TU support true hardware redundancy?
Yes, the MLX90333EGO-BCT-000-TU implements true hardware redundancy via two physically independent silicon dice in a single TSSOP-16 package, with 4 MΩ isolation resistance between them. Each die has dedicated VDD/VSS/VDIG pins, separate SPI interfaces (MOSI1/MISO1/SCLK1/SS1 and MOSI2/MISO2/SCLK2/SS2), and independent output stages - enabling concurrent operation and cross-checking for ASIL-D compliance without external duplication.
How is the MLX90333EGO-BCT-000-TU calibrated for custom transfer characteristics?
The MLX90333EGO-BCT-000-TU is calibrated using the Melexis PTC-04 programming unit, which communicates exclusively through VDD-VSS-OUT pins to program EEPROM-stored parameters. Users configure Alpha/Beta discontinuity points, clamping levels, dead zones, LNR coefficients, and thermal drift compensation - all stored permanently and applied in real time by the on-chip DSP. No external microcontroller or firmware update is required after initial calibration.
Can the MLX90333EGO-BCT-000-TU output both analog and SPI simultaneously?
No, the MLX90333EGO-BCT-000-TU supports only one active output mode at a time - either ratiometric analog, PWM, or SPI serial protocol - selected via MAINMODE and Outputs Mode configuration bits. While dual outputs (OUT1/OUT2) are available in analog/PWM mode for 3D applications, SPI mode uses the same physical pins (MOSI/MISO/SCLK/SS) and disables analog/PWM drivers to avoid contention and ensure signal integrity.
What magnetic field strength is required for reliable operation of the MLX90333EGO-BCT-000-TU?
Reliable operation requires ≥20 mT for BX/BY and ≥24 mT for BZ components, with typical sensitivity at 50 mT (BX/BY) and 140 mT (BZ). The IMC saturates above 70 mT for BX/BY, increasing linearity error, and the device tolerates up to ±4 T absolute flux density without damage. Field thresholds (FIELDTHRES_LOW/HIGH) are user-programmable to adapt detection windows to specific magnet geometries and air gaps.
