Product details
Overview
MLX90367LDC-ACV-000-SP from Melexis is a Triaxis® Hall-effect position sensor IC in SOIC-8 package, delivering 12-bit resolution SENT output per SAE J2716-2010, with programmable 17-point linear transfer characteristic and ±150°C operating range. It decodes absolute rotary or linear position from orthogonal (BX, BY) and parallel (BZ) magnetic field components for non-contacting automotive sensing.
For engineers reviewing the MLX90367LDC-ACV-000-SP datasheet, pinout, applications, or equivalent options, key selection criteria include SENT protocol compliance, thermal offset correction capability, 17-point LNR programmability, and SOIC-8 footprint suitability for pedal, throttle, and steering wheel position systems.
Technical Context
The MLX90367LDC-ACV-000-SP integrates a 16-bit RISC DSP core running at 10 MHz (2.5 MIPS), performing real-time CoRDiC-based rectangular-to-polar conversion on raw sine/cosine ADC outputs. Its on-chip signal processing includes FIR filtering (FILTER=0/1/2), thermal offset correction, and dual-die redundancy support-though this specific variant uses single-die SOIC-8 packaging.
It implements SENT output in Throttle Sensor Format or Secure Sensor Format, delivering enhanced serial messages with diagnostic reporting, user-defined OEM data fields, and error codes. The 48-bit ID number enables full traceability, and EEPROM stores programmable parameters including clamping thresholds, discontinuity point, and 17-point LNR coefficients.

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90367LGO-ACV-000-RE | Dual-die TSSOP-16 variant with full hardware redundancy; higher pin count and isolation resistance (4 MΩ between dice). | Required for ASIL-D functional safety architectures where fault tolerance mandates redundant signal paths. | Select when dual-die redundancy and inter-die isolation are mandatory; not drop-in compatible due to different package and pinout. |
| MLX90367LDC-ACU-000-SP | Same SOIC-8 package but limited to 3-point LNR programmability; lacks 17-point curve and thermal offset correction features. | Suitable for cost-sensitive applications with simpler mechanical profiles and lower thermal stability requirements. | Choose for basic rotary/linear sensing where advanced calibration and thermal drift mitigation are unnecessary. |
Compared with MLX90367LDC-ACV-000-SP, the ACU variant reduces calibration flexibility and thermal compensation capability, while the GO dual-die version adds redundancy at the expense of board space and layout complexity-making the ACV-000-SP optimal for high-accuracy, thermally demanding single-die designs.

FAQ
What is the SENT frame period and latency specification for MLX90367LDC-ACV-000-SP?
The MLX90367LDC-ACV-000-SP delivers SENT frames every 882 µs. With FILTER=1 (recommended), total field-to-data latency is 1745 µs, including internal angle measurement (441 µs), first/second measurement latencies (1084 µs and 643 µs), and SENT transmission. This ensures deterministic timing for automotive ECU synchronization.
Does MLX90367LDC-ACV-000-SP support thermal offset correction, and how is it implemented?
Yes, MLX90367LDC-ACV-000-SP supports thermal output offset correction as part of its AxV option code functionality. It applies on-chip compensation using calibrated coefficients stored in EEPROM, reducing angular error caused by temperature-induced zero-point drift-critical for maintaining accuracy across −40°C to +150°C operation.
What magnetic field ranges does MLX90367LDC-ACV-000-SP support for reliable operation?
MLX90367LDC-ACV-000-SP operates reliably with BX/BY field magnitudes ≥70 mT (to avoid IMC saturation) and BZ ≥126 mT. The magnetic flux norm √[BX² + BY² + (BZ/1.2)²] should remain ≥20 mT to maintain signal-to-noise ratio; below this threshold, performance degrades slightly due to reduced SNR.
Can MLX90367LDC-ACV-000-SP be programmed in-system, and what parameters are user-configurable?
Yes, MLX90367LDC-ACV-000-SP supports full in-system programming via SENT interface. Users can configure 17-point LNR transfer characteristics, clamping limits (CLAMPHIGH/LOW), discontinuity point (DP), clock-wise direction (CW), filter settings (FILTER), diagnostic enable bits, and OEM serial message content-all stored in 128-byte EEPROM with >100k write cycles endurance.
What is the role of the IMC structure in MLX90367LDC-ACV-000-SP, and how does it affect sensitivity?
The Integrated Magneto-Concentrator (IMC®) enhances magnetic field sensitivity in MLX90367LDC-ACV-000-SP, providing gain factors of 1.2–1.8 for X/Y axes and 1.1–1.3 for Z axis. The k factor (IMCXY/IMCZ = 1–1.5) enables axis-specific trimming to correct orthogonality errors, directly improving intrinsic linearity and angular accuracy in both XY and XZ/YZ planes.
