Product details
Overview
MLX90372GVS-ACE-103-RX from Melexis is a monolithic Triaxis® Hall-based magnetic position processor IC for absolute rotary position sensing in stray-field-immune configurations. It delivers SENT output per SAE J2716 APR2016, operates from -40°C to +160°C, supports programmable linear transfer characteristic (up to 32-point PWL), and integrates on-chip DSP and analog signal conditioning. It is used in automotive throttle and steering wheel position sensing where robustness against external magnetic interference is critical.
For engineers reviewing the MLX90372GVS-ACE-103-RX datasheet, pinout, applications, or equivalent options, key selection criteria include its DMP-4 PCB-less package with Pinout-B, SENT 3µs mode, angular rotary stray-field immunity (-100 code), built-in capacitors, and ISO26262 ASIL-C safety compliance.
Technical Context
The MLX90372GVS-ACE-103-RX implements Triaxis® sensing architecture that measures all three orthogonal components (Bx, By, Bz) of magnetic flux density to compute absolute angle without mechanical contact. Its dual-die redundancy is absent-this variant uses a single die in DMP-4 packaging with integrated decoupling capacitors and Pinout-B configuration (OUT/VSS/VDD/Input).
It supports two primary output modes: SENT (SAE J2716 APR2016 compliant, 3µs tick time) and PWM, both configurable via end-user programming. The -103 option code specifies Angular Rotary Strayfield Immune operation (low-field variant), SENT 3µs mode, capacitor configuration #2, and STD2 2.54 trim & form per section 18.11.

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-100-RE/RX | Same DMP-4 Pinout-B package, identical -100 stray-field immune configuration, but uses capacitor configuration #1 (STD1 1.27 trim) | Targeted for legacy board layouts with tighter pitch; lacks STD2 2.54 mechanical compatibility | Select when reusing existing DMP-4 footprint with 1.27 mm lead spacing and standard capacitor layout |
| MLX90372GVS-ACE-101-RE/RX | Same DMP-4 Pinout-B and -100 code, but uses capacitor configuration #2 with STD1 2.54 trim (not recommended for new designs) | Offers same electrical behavior but outdated mechanical form factor per datasheet section 18.10 | Only for continuity in legacy programs; avoid for new designs due to obsolescence notice |
Compared with MLX90372GVS-ACE-103-RX, the -100 variant requires matching 1.27 mm PCB pitch and offers no trim/form upgrade path, while the -101 variant uses obsolete STD1 2.54 geometry - the -103's STD2 2.54 trim provides optimal mechanical robustness and long-term manufacturability for new automotive modules.

FAQ
What is the package type and pin configuration of MLX90372GVS-ACE-103-RX?
The MLX90372GVS-ACE-103-RX uses the DMP-4 (Dual Mould Package) PCB-less package with Pinout-B configuration: Pin 1 = OUT, Pin 2 = VSS, Pin 3 = VDD, Pin 4 = Input. It implements STD2 2.54 trim & form (section 18.11) and includes built-in decoupling capacitors. This differs from Pinout-A variants and SOIC-8/TSSOP-16 versions.
Does MLX90372GVS-ACE-103-RX support PWM output in addition to SENT?
Yes, MLX90372GVS-ACE-103-RX supports both SENT (SAE J2716 APR2016 compliant, 3µs tick time) and PWM output modes. Output selection is programmable via end-user configuration. The -103 option code specifies SENT 3µs mode by default, but PWM remains fully enabled and configurable without hardware change.
What does the "-103" option code signify for MLX90372GVS-ACE-103-RX?
The "-103" option code indicates: (1) Angular Rotary Strayfield Immune operation (low-field variant), (2) SENT 3µs mode with capacitor configuration #2, and (3) STD2 2.54 trim & form per section 18.11. It confirms the device is configured for robust performance in magnetically noisy environments with optimized mechanical packaging.
Is MLX90372GVS-ACE-103-RX certified for functional safety applications?
Yes, MLX90372GVS-ACE-103-RX is qualified as an ISO26262 ASIL-C Safety Element out of Context (SEooC) and AEC-Q100 Grade 0. It includes integrated diagnostics, watchdog timers (IWD/AWD), and fail-safe state capability - enabling its use in ASIL-B and ASIL-C automotive systems without requiring additional safety hardware.
Can the MLX90372GVS-ACE-103-RX measure linear position, or is it limited to rotary sensing?
The MLX90372GVS-ACE-103-RX is configured for Angular Rotary Strayfield Immune operation (-100 code), so its factory calibration and magnetic front-end optimization target rotary applications (e.g., throttle, steering). While the underlying Triaxis® architecture supports linear position sensing, the -103 variant's firmware and characterization are specific to angular use cases.
