Product details
Overview
MLX90366LVS-ADU-250-SP from Melexis is an AEC-Q100 qualified Triaxis® absolute rotary and linear position sensor IC using Hall-effect 3D magnetic field sensing (Bx, By, Bz) with SENT output per SAE J2716-2010, 12-bit resolution, 10-bit thermal accuracy, and programmable piecewise-linear transfer characteristic. It operates across −40 °C to +150 °C and enables non-contacting potentiometer replacement in automotive throttle and steering wheel position sensing.
For engineers reviewing the MLX90366LVS-ADU-250-SP datasheet, pinout, applications, or equivalent options, this page delivers verified technical context, SENT timing compliance, thermal offset correction capability, DMP-4 package mapping, and validated automotive-grade alternatives for pedal, float-level, and ride height sensor designs.
Technical Context
The MLX90366LVS-ADU-250-SP integrates a 16-bit RISC DSP core running at 10 MHz (2.5 MIPS), co-located with analog front-end circuitry that measures orthogonal and parallel magnetic flux components. Its Triaxis® architecture computes absolute angular or linear position via CoRDiC-based rectangular-to-polar conversion of raw sine/cosine signals derived from integrated magneto-concentrators (IMC).
It implements SENT protocol with Throttle Sensor Format frames, delivering 12-bit position data plus diagnostics in fast channel and user-defined values in slow channel. The ADU-250 variant supports 3-point piecewise-linear (LNR) transfer function programming and includes on-board diagnostics such as over-voltage protection, under-voltage detection, and broken-track reporting.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90367LVS-AEU-250-SP | 17-point LNR programmability, same DMP-4 package and SENT interface - adds higher-resolution calibration flexibility. | Preferred for applications requiring tighter linearity after mechanical tolerance stack-up (e.g., high-precision steering angle feedback). | Select when enhanced post-calibration accuracy is needed; requires updated EEPROM programming flow for 17-point tables. |
| TLV493DW2B6HTSA1 | 3D Hall sensor with I²C output, 12-bit resolution, −40 °C to +125 °C - lacks SENT compliance and AEC-Q100 Grade 0 qualification. | Suitable for non-safety-critical industrial position sensing where I²C bus integration is preferred over SENT. | Choose only for cost-sensitive non-automotive designs; not drop-in replaceable due to interface and qualification mismatch. |
Compared with MLX90366LVS-ADU-250-SP, MLX90367LVS-AEU-250-SP offers finer transfer curve granularity for improved mechanical error compensation, while TLV493DW2B6HTSA1 provides I²C convenience at the expense of automotive qualification and SENT compatibility - making the original optimal for production-grade throttle and pedal modules.

FAQ
What is the SENT frame structure used by MLX90366LVS-ADU-250-SP?
The MLX90366LVS-ADU-250-SP transmits SENT frames per SAE J2716-2010 Throttle Sensor Format, containing 12-bit position data in the fast channel and diagnostic flags or OEM-defined values in the slow channel. Frame period is fixed at 882 μs, with sync pulse latency of 1.084 ms for first measurement. Each frame includes CRC and error reporting capability, and the MLX90366LVS-ADU-250-SP supports both pause and non-pause variants depending on configuration.
Does MLX90366LVS-ADU-250-SP support thermal output offset correction?
No, MLX90366LVS-ADU-250-SP does not include thermal output offset correction - that feature is exclusive to AxX-xxx option codes (e.g., ADX-xxx or AEX-xxx). The ADU-250 variant provides standard thermal offset drift performance of ±60 LSB15 over −40 °C to +125 °C and ±90 LSB15 up to +150 °C, compensated via factory-trimmed IMC gain and DSP algorithms within the MLX90366LVS-ADU-250-SP architecture.
What is the magnetic field range supported by MLX90366LVS-ADU-250-SP?
The MLX90366LVS-ADU-250-SP supports magnetic flux densities up to ±70 mT in XY plane (Bx, By) and ±126 mT in Z-axis (Bz), with optimal operation between 20 mT and 70 mT for XY sensing. Below 20 mT, signal-to-noise ratio degrades; above 70 mT, IMC saturation increases linearity error. These values are confirmed in the MLX90366LVS-ADU-250-SP datasheet Section 9 and apply directly to this specific option code.
Can MLX90366LVS-ADU-250-SP be used without a printed circuit board?
Yes, MLX90366LVS-ADU-250-SP is designed for "NoPCB" module integration using its DMP-4 package - the die is pre-mounted on a leadframe with integrated magneto-concentrator and wire-bonded, allowing direct encapsulation into plastic housings. This eliminates PCB-related failure modes and enhances mechanical robustness in vibration-prone automotive applications, as specified in the MLX90366LVS-ADU-250-SP functional description and package documentation.
Is MLX90366LVS-ADU-250-SP pin-compatible with other MLX90366 variants?
Yes, all MLX90366 variants - including MLX90366LVS-ADU-250-SP - share identical DMP-4 4-pin pinout (VSS, VDD, OUT, VSS) and mechanical footprint. Electrical behavior (e.g., SENT timing, programmability, diagnostics) varies by option code, but PCB layout, soldering, and interconnect remain fully interchangeable across the MLX90366 family, enabling flexible qualification and revision management without hardware redesign.
