Product details
Overview
MLX90367KDC-ABV-000-RE from Melexis is a Triaxis® monolithic Hall-effect position sensor IC that measures all three orthogonal magnetic field components (BX, BY, BZ) to compute absolute rotary or linear position. It delivers 12-bit resolution with 10-bit thermal accuracy, SENT output per SAE J2716-2010, and operates from −40 °C to +150 °C in SOIC-8 package. Used in automotive throttle and steering wheel position sensing.
For engineers reviewing the MLX90367KDC-ABV-000-RE datasheet, pinout, applications, or equivalent options, key selection criteria include SENT protocol compliance, thermal offset correction capability, programmable multi-point transfer characteristic, Triaxis® field vector decoding, and AEC-Q100 qualification for high-reliability automotive sensing.
Technical Context
The MLX90367KDC-ABV-000-RE integrates on-chip analog signal processing (ASP) and digital signal processing (DSP) based on a 16-bit RISC microcontroller running at 10 MHz (2.5 MIPS). Its Triaxis® architecture uses an integrated magneto-concentrator (IMC) to enhance sensitivity to orthogonal and parallel flux components, enabling robust angle computation via CoRDiC-based rectangular-to-polar transformation.
It supports SENT frame transmission in Throttle Sensor or Secure Sensor format, with configurable fast/slow channels, diagnostic reporting, and user-defined serial messages. The device features factory-trimmed k-factor calibration for XZ/YZ axis linearity and programmable clamping, discontinuity point, and clock-wise direction settings.

Pinout & Package
MLX90367KDC-ABV-000-RE is housed in an 8-pin SOIC package (package code "DC"). Unused test pins must be connected to ground for optimal EMC performance per datasheet recommendation.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VDD | Main supply voltage input (4.5–5.5 V); decoupling capacitor required near pin. |
| 2 | Test 0 | Factory test pin; must be connected to VSS (ground) for EMC compliance. |
| 3 | Test 2 | Factory test pin; must be connected to VSS (ground) for EMC compliance. |
| 4 | Not Used | No internal connection; connect to VSS (ground) per datasheet Section 17. |
| 5 | OUT | SENT serial output (open-drain, 18 V tolerant); requires external pull-up resistor (14.7 kΩ typical). |
| 6 | Test 1 | Factory test pin; must be connected to VSS (ground) for EMC compliance. |
| 7 | VDIG | Digital supply domain; internally tied to VDD in single-die SOIC-8 variant. |
| 8 | VSS | Ground reference for analog and digital domains; low-impedance return path required. |
Key Features
| Feature | Design Value |

| Thermal Offset Correction | Compensates for temperature-induced output drift using on-chip algorithms, maintaining <±0.3° angular error over full operating range. |
| 48-bit Unique ID | Factory-programmed EEPROM ID enables full traceability and secure serialization for OEM quality control and anti-counterfeiting. |
Applications
| Throttle Position Sensing | Steering Wheel Angle Sensing |
|---|---|
Use Scenario: Measures pedal travel in electronic throttle control (ETC) systems for precise engine torque management. IC Role / Device Role / Timing Role: Absolute rotary position sensor providing SENT-encoded angle data synchronized to ECU timing requirements.

IC Role / Device Role / Timing Role: High-reliability absolute angle sensor delivering SENT frames with diagnostic status every 882 µs. Use Value: Enables fail-operational redundancy support via dual-die variants; SOIC-8 version provides cost-optimized single-channel solution. |
| Pedal Position Sensing | Ride Height Control |
Use Scenario: Monitors accelerator/brake pedal displacement in brake-by-wire and drive-by-wire architectures. IC Role / Device Role / Timing Role: Linear position transducer converting magnet stroke into SENT-coded 12-bit position value.

Use Value: Immune to dust, moisture, and vibration; IMC-enhanced sensitivity ensures stable operation even with weak magnetic fields (<70 mT). |
Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90367KGO-ACX-000-RE | Dual-die TSSOP-16 package with full redundancy; includes thermal output offset correction and 17-point LNR calibration. | Required for ASIL-D redundant architectures; higher pin count and board area vs. SOIC-8. | Select when functional safety mandates dual-channel independence and diagnostic coverage beyond single-die capability. |
| MLX90363KDC-ABG-000-RE | Legacy Triaxis® sensor with PWM output only; no SENT interface; 10-bit resolution; no programmable LNR or thermal correction. | Limited to legacy systems without SENT bus infrastructure; lower accuracy and fewer calibration options. | Choose only for cost-sensitive, non-SAE-J2716 designs where SENT is not required and thermal drift is mitigated externally. |
Compared with MLX90367KDC-ABV-000-RE, the ACX-000 variant adds hardware-level redundancy and advanced thermal compensation for safety-critical systems, while the ABG-000 offers basic PWM output at lower cost but sacrifices SENT diagnostics, resolution, and programmability.

FAQ
What is the operating temperature range of the MLX90367KDC-ABV-000-RE?
The MLX90367KDC-ABV-000-RE is rated for operation from −40 °C to +150 °C, meeting AEC-Q100 Grade 0 requirements. This wide range supports placement in demanding automotive locations such as near engines or transmissions. The device maintains specified accuracy and SENT functionality across this full range, with thermal offset correction actively compensating for drift. MLX90367KDC-ABV-000-RE achieves this via on-chip temperature sensing and calibrated DSP algorithms.
Does the MLX90367KDC-ABV-000-RE support SENT protocol version compatibility?
Yes, the MLX90367KDC-ABV-000-RE implements SENT per SAE J2716-2010 and supports both Throttle Sensor and Secure Sensor frame formats. It allows configuration of fast channel diagnostics and slow channel extended serial messages. Frame period is fixed at 882 µs, and CRC options include 2007 or 2010 standards. MLX90367KDC-ABV-000-RE does not support J2716-2017 revisions with variable frame lengths or enhanced security extensions.
Can the MLX90367KDC-ABV-000-RE be programmed in-system after soldering?
Yes, the MLX90367KDC-ABV-000-RE supports end-user programming via its SENT interface using standard Melexis programming tools (e.g., EVB90367 evaluation board and MLX IDE). Parameters including transfer characteristic points, clamping limits, discontinuity point, and diagnostic settings can be written to EEPROM. MLX90367KDC-ABV-000-RE allows lock/unlock sequences to prevent accidental reprogramming, and memory endurance exceeds 100,000 write cycles per location.
What magnetic field strength is required for reliable operation of the MLX90367KDC-ABV-000-RE?
The MLX90367KDC-ABV-000-RE requires a minimum magnetic flux density of 70 mT in the XY plane (or 126 mT in BZ) for optimal linearity and signal-to-noise ratio. Below 20 mT, performance degrades due to reduced SNR. The integrated magneto-concentrator (IMC) enhances sensitivity, allowing use with small, low-cost magnets. MLX90367KDC-ABV-000-RE's intrinsic linearity error is specified at ±1° for XY and ±2.5° for XZ/YZ axes under ideal field conditions.
Is the MLX90367KDC-ABV-000-RE pin-compatible with other MLX90367 variants?
Yes, all SOIC-8 packaged MLX90367 variants-including MLX90367KDC-ABV-000-RE, MLX90367KDC-ACU-000-RE, and MLX90367KDC-ACV-000-RE-share identical pinout, footprint, and electrical interface. Differences lie in factory-programmed EEPROM content (e.g., LNR table size, thermal correction enablement), not hardware connectivity. MLX90367KDC-ABV-000-RE is not pin-compatible with TSSOP-16 dual-die versions due to different pin count and assignment.
