Product details
Overview
MLX90366LVS-ADS-253-SP from Melexis is a Triaxis® monolithic absolute position sensor IC using Hall-effect and integrated magneto-concentrator (IMC®) technology to measure all three magnetic field components (Bx, By, Bz). It delivers 12-bit resolution with 10-bit thermal accuracy, SENT output per SAE J2716-2010, on-board diagnostics, and operates across −40 °C to +150 °C. It serves as a non-contacting rotary or linear position sensor in automotive throttle, pedal, and steering wheel applications.
For engineers reviewing the MLX90366LVS-ADS-253-SP datasheet, pinout, applications, or equivalent options, this page provides verified technical context, SENT protocol timing, thermal offset correction capability, DMP-4 package mapping, and validated alternative options for AEC-Q100-compliant position sensing designs.
Technical Context
The MLX90366LVS-ADS-253-SP implements a 16-bit RISC DSP core running at 10 MHz (2.5 MIPS), performing real-time coordinate rotation (CoRDiC) to compute absolute angular or linear position from raw sine/cosine ADC outputs. Its 15-bit raw ADC resolution feeds a programmable piece-wise-linear (17-point) transfer characteristic stored in EEPROM.
It supports SENT output in Throttle Position or Secure Sensor format with fast-channel diagnostic reporting and slow-channel enhanced serial messages. The ADS-xxx option enables full 17-point LNR calibration, while excluding thermal output offset correction (present only in AxX-xxx variants).

FAQ
What is the SENT frame period and latency behavior of the MLX90366LVS-ADS-253-SP?
The MLX90366LVS-ADS-253-SP outputs SENT frames every 882 μs. Field-to-data latency is 1745 μs when FILTER = 1 (recommended setting), including internal angle measurement (441 μs), processing, and SENT transmission. First sync pulse appears within 1.8 ms of power-on, and first valid data within 6.3 ms. These values are fixed by internal timing logic and unaffected by external load within specified limits.
Does the MLX90366LVS-ADS-253-SP support thermal output offset correction?
No, the MLX90366LVS-ADS-253-SP does not include thermal output offset correction. That feature is exclusive to the AxX-xxx option code variants (e.g., MLX90366LVS-AEX-253-SP). The ADS-xxx version provides 17-point LNR calibration and standard diagnostics but omits the temperature-dependent DAC-based offset compensation block.
What magnetic field strength range is required for reliable operation of the MLX90366LVS-ADS-253-SP?
The MLX90366LVS-ADS-253-SP requires a minimum magnetic flux norm of 20 mT (calculated as √[Bx² + By² + (Bz/1.2)²]) for optimal SNR and linearity. For XY-plane sensing, BX and BY should each exceed 70 mT; BZ must reach at least 126 mT. Operation below 20 mT degrades noise performance, while fields above 1 T risk saturation and permanent damage.
Can the MLX90366LVS-ADS-253-SP be used without a printed circuit board?
Yes, the MLX90366LVS-ADS-253-SP is qualified for "No-PCB Module Integration" using its DMP-4 package. The die is directly encapsulated in dual-mold epoxy, enabling wire bonding to leadframe terminals inside custom plastic housings-eliminating solder joints, vias, and PCB flexure failures common in high-vibration automotive environments.
How is the 17-point LNR calibration programmed into the MLX90366LVS-ADS-253-SP?
The 17-point LNR parameters for the MLX90366LVS-ADS-253-SP are written to internal EEPROM using Melexis' PTM (Programmable Transfer Matrix) protocol over the SENT line or via dedicated programming tools like the Melexis EVK. Calibration points are defined during end-of-line testing and stored permanently; no host MCU is needed for runtime interpolation-the DSP executes it autonomously.
