Product details
Overview
MLX90366LVS-ADS-253-RX from Melexis is an AEC-Q100 qualified Triaxis® absolute position sensor IC using Hall-effect 3D magnetic field sensing (Bx, By, Bz) to deliver 12-bit angular/linear position data via SENT output (SAE J2716-2010 Throttle format), with 17-point programmable transfer characteristic and automotive-grade thermal accuracy (10-bit over −40°C to +150°C). It enables non-contacting rotary and linear position sensing in throttle, pedal, and steering wheel applications.
For engineers reviewing the MLX90366LVS-ADS-253-RX datasheet, pinout, applications, or equivalent options, key selection criteria include SENT protocol compliance, 17-point LNR calibration capability, DMP-4 package integration for PCB-less module design, and diagnostic features including over-voltage protection and on-board diagnostics.
Technical Context
The MLX90366LVS-ADS-253-RX implements a 16-bit RISC DSP core running at 10 MHz (2.5 MIPS) to compute absolute angle from orthogonal and parallel magnetic flux components. Its internal architecture includes integrated magneto-concentrators (IMC®), configurable FIR filtering (FILTER=0/1/2), and dual VSS pins supporting robust grounding in noisy automotive environments.
It delivers SENT frames with 294-tick period (882 µs frame time), supports both fast-channel diagnostics and slow-channel enhanced serial messages, and features factory-trimmed intrinsic linearity error (±1° XY axis) plus user-programmable clamping, discontinuity point, and clock-wise rotation direction.
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 |
|---|---|---|---|
| MLX90366LVS-AEV-253-RX | Same DMP-4 package and ADS-253 option code, but AEV variant includes identical 17-point LNR calibration and same SENT protocol - differs only in internal firmware revision and EEPROM lock configuration. | Identical use cases (throttle, pedal, steering); AEV-253 supports full EEPROM locking (MEMLOCK=2), while ADS-253 does not implement lock functionality per datasheet section 14.3. | Select AEV-253 when permanent write-protection of calibration parameters is required; ADS-253 is appropriate for designs needing post-production calibration updates. |
| MLX90366LVS-AEX-253-RX | Includes thermal output offset correction (enabled in AxX-xxx variants), which ADS-253 lacks - adds dynamic compensation for temperature-induced zero-point drift beyond fixed calibration. | Suitable for ultra-high-accuracy applications like active suspension or steer-by-wire where <±0.1° thermal stability is mandatory; ADS-253 relies on static 17-point LNR and factory trim only. | Choose AEX-253 when operating ambient exceeds 125°C or when long-term thermal drift must be minimized below ±0.15°; ADS-253 suffices for standard engine bay applications. |
Compared with MLX90366LVS-AEV-253-RX, the MLX90366LVS-ADS-253-RX offers identical position accuracy and SENT timing but omits EEPROM lock capability - simplifying reprogramming workflows. Versus MLX90366LVS-AEX-253-RX, it lacks real-time thermal offset correction, trading some high-temperature precision for lower firmware complexity and cost.

FAQ
What is the SENT protocol configuration supported by MLX90366LVS-ADS-253-RX?
The MLX90366LVS-ADS-253-RX implements the SAE J2716-2010 Throttle position sensor format with 294-tick frames (882 µs period), including fast-channel diagnostics and slow-channel enhanced serial messages. It outputs calibrated position data in SENT frames with user-defined OEM fields and supports pause pulses per section 13.3.3 of the datasheet. The MLX90366LVS-ADS-253-RX does not support PWM or analog output modes.
Does MLX90366LVS-ADS-253-RX support thermal offset correction?
No, MLX90366LVS-ADS-253-RX does not include thermal output offset correction. That feature is exclusive to AxX-xxx option codes (e.g., AEX-xxx), as specified in datasheet section 14.1.6. The ADS-253 variant provides 17-point LNR calibration and factory-trimmed thermal drift compensation but relies on static calibration rather than real-time thermal correction algorithms.
What is the meaning of "ADS-253" in MLX90366LVS-ADS-253-RX?
"ADS-253" denotes the option code: "AD" indicates it is a standard version (not recommended for new design per Table 1 footnote), "S" specifies 17-point piecewise-linear (LNR) transfer characteristic programming, and "253" identifies the trim-and-form STD2 2.54 mm package variant with specific capacitance configuration and lead form. The MLX90366LVS-ADS-253-RX is fully functional and qualified, though Melexis recommends newer AEV/AEX variants for new designs.
Can MLX90366LVS-ADS-253-RX operate without a printed circuit board?
Yes, the MLX90366LVS-ADS-253-RX uses the DMP-4 package optimized for No-PCB module integration, where the die is directly mounted into plastic housings with wire-bonded interconnects. This eliminates PCB-related failure modes and improves mechanical robustness - confirmed in the datasheet description and section 19.5 pinout documentation.
What diagnostic capabilities does MLX90366LVS-ADS-253-RX provide?
The MLX90366LVS-ADS-253-RX includes on-board diagnostics such as broken-track detection (VDD/VSS open-circuit), SENT frame error reporting, watchdog timeout (118 ms typical), and EEPROM CRC checking. Diagnostic status is communicated via fast-channel SENT bits and slow-channel serial messages, with configuration enabled via DIAGSETTINGS register (0xFDFF default for ADS-xxx).
