Product details
Overview
MLX90372GVS-ACE-203-RE 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, supports programmable 4–32-point piecewise linear transfer characteristics, and features ISO26262 ASIL-C safety compliance as a Safety Element out of Context (SEooC). It is used in automotive throttle, pedal, and steering wheel position sensing where stray-field immunity and functional safety are required.
For engineers reviewing the MLX90372GVS-ACE-203-RE datasheet, pinout, applications, or equivalent options, this page provides verified package mapping (DMP-4 Pinout-B), confirmed SENT/PWM timing modes, validated stray-field immune operation in legacy angular/linear mode (-203 option code), and real-world design meaning for diagnostics, startup behavior, and output drive capability.
Technical Context
The MLX90372GVS-ACE-203-RE implements a Triaxis® Hall front end sensitive to Bx, By, and Bz magnetic field components, enabling absolute angle decoding up to 360° or linear displacement without contact. Its on-chip DSP performs real-time signal conditioning, filtering (FIR/EMA), and programmable transfer function mapping using up to 32 PWL points.
This variant uses DMP-4 Pinout-B configuration (VSS/VDD/OUT/Input), supports SENT 3µs mode with built-in capacitors, and is factory-configured for legacy angular/linear position sensing (option -203) with standard stray-field robustness. It includes dual watchdogs (IWD/AWD), diagnostic cycle timing (DCTDIG = 20 ms), and failsafe state activation within 11.9–34.6 ms after digital fault detection.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar magnetic position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90371GVS-ABD-203-RE | Single-die predecessor; no ASIL-C SEooC certification; fixed 8-point PWL only; SENT 1.5 µs mode only. | Lacks diagnostic coverage and programmability needed for new ASIL-B/C designs; limited to legacy platforms. | Select only for cost-sensitive, non-safety-critical linear position applications where upgrade path to MLX90372 is not required. |
| AMS AS5055A-BQFT | Optical encoder IC; requires codewheel; no magnetic stray-field immunity; 12-bit resolution only; no SENT output. | Suitable for clean industrial encoders but fails automotive EMC and temperature requirements; no functional safety support. | Consider only for indoor, low-EMI environments where optical precision outweighs magnetic robustness and safety needs. |
Compared with MLX90372GVS-ACE-203-RE, the MLX90371 offers lower cost but no ASIL-C foundation or flexible transfer functions, while the AS5055A requires mechanical alignment and lacks automotive qualification - making MLX90372GVS-ACE-203-RE the only option supporting both functional safety and stray-field immunity in DMP-4 form factor.

FAQ
What is the package type and pin configuration of MLX90372GVS-ACE-203-RE?
The MLX90372GVS-ACE-203-RE uses the DMP-4 (Dual Mould Package) with Pinout-B configuration: Pin 1 = OUT, Pin 2 = VSS, Pin 3 = VDD, Pin 4 = Input. This variant supports NTC thermistor interfacing or analog/digital gateway functionality on the Input pin and is delivered in tape-and-reel (2500 pcs/reel). The STD2 2.54 mm trim & form matches standard SMT placement tooling.
Does MLX90372GVS-ACE-203-RE support SENT and PWM output simultaneously?
No - the MLX90372GVS-ACE-203-RE supports either SENT or PWM output, selected during programming. Factory default is SENT 3µs mode. PWM mode provides variable-duty-cycle signaling compatible with legacy ECU inputs, while SENT delivers richer diagnostics, CRC, and 48-bit ID. Switching requires reprogramming via Melexis PTC tools and cannot be changed dynamically in operation.
What does the "-203" option code signify for MLX90372GVS-ACE-203-RE?
The "-203" option code indicates Legacy / Angular Rotary / Linear position configuration with standard stray-field immunity (not high- or low-field variants). It corresponds to chip revision ACE (preferred for new designs), DMP-4 package (VS), and STD2 2.54 mm trim & form. This setting enables full 32-point PWL programmability and SENT 3µs timing mode with built-in capacitors per section 15.3 of the datasheet.
Is MLX90372GVS-ACE-203-RE qualified for automotive use?
Yes - MLX90372GVS-ACE-203-RE is AEC-Q100 Grade 0 qualified (-40°C to +160°C), certified to ISO26262 ASIL-C as a Safety Element out of Context (SEooC), and designed for automotive powertrain, chassis, and body applications. Its DMP-4 package meets humidity resistance and thermal cycling requirements per JESD22-A101 and JESD22-A108.
How is stray-field immunity implemented in MLX90372GVS-ACE-203-RE?
MLX90372GVS-ACE-203-RE achieves stray-field immunity through Triaxis® 3D Hall sensing combined with on-chip differential signal processing and adaptive filtering (FIR/EMA). In -203 mode, it rejects uniform external fields up to ±1 mT while maintaining ±0.5° angular accuracy - verified per section 8.4 of the datasheet and validated in engine bay EMC testing per ISO11452-8.
