Product details
Overview
MLX90372GVS-ACE-203-RX from Melexis is a monolithic Triaxis® Hall-based magnetic position processor IC for absolute rotary and linear position sensing. It delivers SENT or PWM output, operates from -40°C to +160°C, features ISO26262 ASIL-C safety certification, and uses a PCB-less DMP-4 package with Pinout-B configuration for compact automotive sensor modules.
For engineers reviewing the MLX90372GVS-ACE-203-RX datasheet, pinout, applications, or equivalent options, key selection factors include its DMP-4 Pinout-B interface (VDD/VSS/OUT/Input), SENT 3µs mode support, stray-field immune legacy-mode operation (-203 option code), and integrated diagnostics for pedal, throttle, and steering wheel position systems.
Technical Context
The MLX90372GVS-ACE-203-RX implements a Triaxis® front end that measures all three orthogonal magnetic field components (Bx, By, Bz) to compute absolute angular or linear position without mechanical contact. Its on-chip DSP supports programmable piecewise linear (PWL) transfer characteristics with up to 32 points and configurable filtering for robustness in high-EMI environments.
This variant uses DMP-4 Pinout-B (OUT/VSS/VDD/Input), enabling NTC temperature sensing or analog/digital gateway functionality via the Input pin. It operates in Standard/Legacy Mode (-203 option code), supporting both angular rotary and linear position applications with SENT 3µs timing and built-in decoupling capacitors per section 15.3 of the datasheet.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Temp | -40°C to +160°C - Enables under-hood and transmission-mounted deployment without external thermal derating. |
| Supply Voltage | 4.5 V to 5.5 V (regulated) or 6 V to 18 V (battery) - Supports direct battery connection with overvoltage protection at 21.5–24.5 V. |
| Output Interface | SENT (SAE J2716 APR2016) or PWM - SENT frames include error codes and user-defined values; PWM duty cycle encodes position. |
| Accuracy (Legacy Mode) | ±0.3° typical angular error - Validated across full 0–360° range with calibrated magnet assembly per datasheet section 9.5. |
| Supply Current | 8.0–10.5 mA - Optimized for low-power continuous operation in always-on vehicle subsystems. |

Key Features
| Feature | Design Value |
|---|---|
| Triaxis® 3D Hall Sensing | Measures Bx, By, Bz simultaneously to resolve absolute angle or displacement from a single moving magnet - eliminates need for multi-die or external concentrators. |
| Programmable PWL Transfer | Up to 32-point piecewise linear calibration - enables precise linearization of non-ideal magnetic circuits without host MCU intervention. |
| SENT Secure Sensor Format | Includes CRC, diagnostic flags, and 48-bit ID - allows secure ECU-level validation of sensor identity and health status in real time. |
| Stray-Field Immunity (Legacy Mode) | Validated operation under ±100 mT external DC fields - maintains accuracy in proximity to electric powertrain components. |
| DMP-4 Pinout-B Integration | Built-in decoupling capacitors and NTC-ready Input pin - reduces BOM count by 3–5 passive components and enables direct thermistor readout. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar magnetic position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90372GVS-ACE-300-RX | Same DMP-4 Pinout-B package and -203-compatible hardware; differs only in option code (-300 = Legacy Mode without stray-field immunity tuning) | Designed for general-purpose angular/linear sensing where stray-field immunity is not required | Select when magnetic environment is controlled and cost optimization is prioritized over field resilience |
| MLX90371GVS-ABD-100-RE | Predecessor Triaxis® IC in DMP-4; lacks SENT protocol, ISO26262 ASIL-C certification, and programmable PWL (fixed 8-point) | Targeted at legacy designs requiring PWM-only output and no functional safety compliance | Choose only for backward compatibility; not recommended for new ASIL-B/C designs per Melexis documentation |
Compared with MLX90372GVS-ACE-203-RX, the -300 variant offers identical packaging and interface but reduced stray-field tolerance, while the MLX90371 lacks SENT, safety certification, and advanced calibration-making the MLX90372GVS-ACE-203-RX the only option supporting ASIL-C-compliant SENT output in DMP-4 Pinout-B form factor.

This layout supports NTC temperature sensing or analog/digital gateway functionality and includes built-in decoupling capacitors per datasheet section 15.3.
Does MLX90372GVS-ACE-203-RX support SENT protocol, and what version is implemented?
Yes, MLX90372GVS-ACE-203-RX supports SENT output compliant with SAE J2716 APR2016, including Secure Sensor format with CRC, diagnostic flags, and 48-bit ID. It operates in SENT 3µs mode per its ACE-203 option code and DMP-4 Pinout-B configuration.
What does the "-203" option code signify for MLX90372GVS-ACE-203-RX?
The "-203" option code indicates Legacy / Angular Rotary / Linear position mode (digit '3') with STD2 2.54 mm trim and form (digit '3' in third position), per Table 2. It configures the device for standard magnetic field sensitivity without stray-field immunity tuning, and enables DMP-4 Pinout-B functionality including the Input pin for NTC or gateway use.
Is MLX90372GVS-ACE-203-RX certified for automotive functional safety standards?
Yes, MLX90372GVS-ACE-203-RX is certified to ISO26262 ASIL-C as a Safety Element out of Context (SEooC) and qualified to AEC-Q100 Grade 0. These certifications are documented in the official datasheet revision 8 and apply directly to this part number's silicon revision and package configuration.
Can MLX90372GVS-ACE-203-RX output PWM instead of SENT?
Yes, MLX90372GVS-ACE-203-RX supports selectable PWM output in addition to SENT. The output mode is programmable via end-user configuration; PWM provides pulse-width modulated position data with configurable frequency and filtering, serving as a fallback or alternative interface in systems lacking SENT-capable ECUs.
