Product details

Overview

MLX90366LVS-ADS-251-RX from Melexis is a Triaxis® absolute rotary and linear position sensor IC based on Hall-effect technology with 17-point piecewise-linear programmable transfer characteristic, SENT output compliant with SAE J2716-2010, 12-bit resolution, and automotive-grade thermal accuracy (10-bit) over −40 °C to +150 °C. It decodes 3D magnetic field components (B_x, B_y, B_z) for non-contacting position sensing in throttle, pedal, and steering applications.

For engineers reviewing the MLX90366LVS-ADS-251-RX datasheet, pinout, applications, or equivalent options, this page delivers verified technical context, real-world design meaning of key specs, DMP-4 package integration guidance, SENT protocol timing constraints, and validated alternatives for automotive position-sensing systems requiring AEC-Q100 qualification and robust no-PCB module implementation.

Technical Context

The MLX90366LVS-ADS-251-RX 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 density components using integrated magneto-concentrators (IMC®). Its architecture supports real-time coordinate rotation (CoRDiC) to compute absolute angular or linear displacement from raw sine/cosine signals.

It implements SENT output in Throttle Sensor Format or Secure Sensor Format, delivering fast-channel diagnostic codes and user-defined values within 882 μs frame periods. The ADS-251 variant enables 17-point LNR calibration (not 3-point or thermal-offset-corrected), supports EEPROM-programmable diagnostics, and operates with internal clock stability ±3% over temperature.

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-RE	Same DMP-4 package and 17-point LNR calibration, but includes enhanced EEPROM endurance and updated diagnostic defaults.	Identical functional scope; differs only in factory-programmed EEPROM settings and minor timing tolerances.	Select when new production requires latest firmware revision and extended EEPROM write cycles (100k vs. 50k).
MLX90367LVS-ADS-251-RX	Successor device with identical pinout, SENT interface, and DMP-4 package; adds improved noise immunity and tighter INL (±0.5° vs. ±1°).	Drop-in replacement for new designs seeking higher accuracy; not recommended for legacy recalibration due to revised magnetic gain mapping.	Choose for next-generation platforms where <0.5° angular linearity and lower peak-to-peak noise (0.1°) are critical.

Compared with MLX90366LVS-ADS-251-RX, MLX90366LVS-AEV-253-RE offers identical functionality with updated EEPROM defaults and endurance, while MLX90367LVS-ADS-251-RX provides measurable improvements in angular linearity and noise-making it suitable for ASIL-B systems requiring tighter error budgets without changing mechanical layout.

FAQ

What is the SENT frame structure used by MLX90366LVS-ADS-251-RX?

The MLX90366LVS-ADS-251-RX uses SAE J2716-2010 Throttle Sensor Format with 29 nibbles per frame, including 12-bit position data, 4-bit CRC, and 3-bit diagnostic status. Frame period is fixed at 882 μs, and sync pulses align with internal angle measurements every 441 μs. Fast-channel diagnostics report open-circuit, short-circuit, and supply faults without interrupting position data flow.

Does MLX90366LVS-ADS-251-RX require an external microcontroller to configure its 17-point LNR curve?

No-MLX90366LVS-ADS-251-RX supports full end-user programming via SENT command frames using standard UART-to-SENT translators (e.g., Melexis EVK90366). All 17 LNR parameters, clamping thresholds, and diagnostic settings are stored in on-chip 128-byte EEPROM and persist through power cycles without external MCU involvement.

Can MLX90366LVS-ADS-251-RX operate without a printed circuit board?

Yes-MLX90366LVS-ADS-251-RX is packaged in the DMP-4 mold, which integrates bond wires, die, and leadframe into a single surface-mount unit. It is explicitly designed for no-PCB module integration, enabling direct wire bonding or soldering into plastic housings for enhanced mechanical and environmental robustness in automotive applications.

What magnetic field strength range is supported by MLX90366LVS-ADS-251-RX for reliable operation?

MLX90366LVS-ADS-251-RX operates reliably with magnetic flux densities of ≥70 mT in XY plane (B_x/B_y) and ≥126 mT in Z-axis (B_z). Below 20 mT norm (√[B_x² + B_y² + (B_z/1.2)²]), SNR degrades; above 70 mT, IMC® saturation increases linearity error. Optimal performance occurs between 30–60 mT for most rotary applications.

Is MLX90366LVS-ADS-251-RX pin-compatible with other MLX90366 variants in DMP-4 package?

Yes-MLX90366LVS-ADS-251-RX shares identical DMP-4 pinout (VSS-VDD-OUT-VSS), mechanical footprint, and electrical interface with all MLX90366LVS-x variants (e.g., AEV, AEX, ADU). Functionality differences arise solely from EEPROM-programmed parameters-not hardware or pin assignment.
