Product details
Overview
MLX90366LVS-ADU-253-SP from Melexis is an AEC-Q100 qualified Triaxis® absolute position sensor IC using Hall-effect technology to measure orthogonal (Bx, By) and parallel (Bz) magnetic flux components. It delivers 12-bit resolution with 10-bit thermal accuracy, SENT output per SAE J2716-2010, and programmable multi-point transfer characteristics. It serves as a non-contacting rotary or linear position transducer in automotive throttle and steering wheel sensing.
For engineers reviewing the MLX90366LVS-ADU-253-SP datasheet, pinout, applications, or equivalent options, key selection criteria include SENT protocol compliance, thermal offset correction capability, DMP-4 package integration, automotive-grade diagnostics, and programmable piecewise-linear transfer function for custom magnetic field mapping.
Technical Context
The MLX90366LVS-ADU-253-SP integrates a 16-bit RISC DSP core running at 10 MHz (2.5 MIPS), on-chip IMC® magneto-concentrator, and dual-stage signal processing (analog front-end + digital angle computation). Its CoRDiC-based coordinate rotation engine computes absolute angular position from raw Bx/By/Bz inputs with factory-trimmed orthogonality and sensitivity mismatch compensation.
It implements SENT frame transmission with Throttle Sensor Format or Secure Sensor Format, supporting fast-channel diagnostics and slow-channel enhanced serial messages. The ADU-253 variant includes 17-point LNR programmability and thermal output offset correction, enabling high-accuracy calibration across -40°C to +150°C ambient range.

FAQ
What is the SENT frame period and latency behavior of the MLX90366LVS-ADU-253-SP?
The MLX90366LVS-ADU-253-SP transmits SENT frames every 882 μs. Field change to SENT data average latency is 1745 μs when FILTER = 1 (recommended setting). First sync pulse appears within 1.8 ms of power-on, and first valid data is delivered within 6.3 ms. These timing values are fixed by internal clock (13.3 MHz typical) and firmware configuration, and are consistent across all ADU-xxx variants including MLX90366LVS-ADU-253-SP.
Does the MLX90366LVS-ADU-253-SP support both rotary and linear position sensing?
Yes, the MLX90366LVS-ADU-253-SP supports both absolute rotary and linear position sensing via its Triaxis® architecture. It measures Bx, By, and Bz components simultaneously, enabling angular computation (0–360°) from rotating magnets or linear displacement from axial magnet motion. The ADU-253 option includes 17-point programmable transfer characteristics to adapt the output curve to either geometry, and thermal offset correction ensures accuracy across the full -40°C to +150°C range for both use cases.
What diagnostics does the MLX90366LVS-ADU-253-SP provide, and how are they reported?
The MLX90366LVS-ADU-253-SP provides on-board diagnostics including broken VSS/VDD detection, output short-circuit monitoring, and SENT frame error reporting. Diagnostic status is embedded in the SENT fast channel (Throttle Sensor Format) as defined in SAE J2716-2010. Specific flags indicate supply faults, open-load conditions, and internal sensor errors. The MLX90366LVS-ADU-253-SP also supports enhanced serial messages in the slow channel for user-defined diagnostic data and EEPROM CRC validation.
Is the MLX90366LVS-ADU-253-SP pin-compatible with other MLX90366 variants in the DMP-4 package?
Yes, all MLX90366 variants in the DMP-4 package - including MLX90366LVS-ADU-253-SP, MLX90366LVS-AEV-253-SP, and MLX90366LVS-AEX-253-SP - share identical 4-pin pinout (VSS, VDD, OUT, VSS), mechanical dimensions, and solder footprint. This allows drop-in replacement during design iteration or qualification, provided firmware and EEPROM programming align with the specific feature set (e.g., thermal offset correction is enabled only in ADU and AEX variants).
What magnetic field strength is required for reliable operation of the MLX90366LVS-ADU-253-SP?
The MLX90366LVS-ADU-253-SP requires minimum magnetic flux densities of 70 mT for Bx/By and 126 mT for Bz under typical operating conditions. The integrated IMC® structure provides gain of 1.2–1.8× in X/Y and 1.1–1.3× in Z, allowing use with standard NdFeB magnets at air gaps up to 4 mm. Operation below 20 mT norm degrades SNR and increases noise (up to 0.2° pk-pk), while fields above 70 mT risk IMC saturation and increased linearity error - both thresholds are specified in the MLX90366LVS-ADU-253-SP datasheet Section 9.
