Product details
Overview
MLX90372GVS-ACE-303-SP 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 compliance, and supports programmable transfer characteristics (up to 32-point PWL) in a PCB-less DMP-4 package with Pinout-B configuration.
For engineers reviewing the MLX90372GVS-ACE-303-SP datasheet, pinout, applications, or equivalent options, this page provides verified functional context, validated DMP-4 Pinout-B terminal roles, confirmed SENT/PWM timing modes, stray-field-immune legacy-mode accuracy specs, and direct alternative options for automotive pedal, throttle, and steering position sensing.
Technical Context
The MLX90372GVS-ACE-303-SP implements Triaxis® sensing-measuring Bx, By, and Bz components-to compute absolute angular or linear position without mechanical contact. Its on-chip DSP enables real-time signal conditioning, programmable piecewise-linear (PWL) transfer functions, and dual diagnostics paths (analog and digital) with configurable watchdog timeouts.
This variant uses DMP-4 Pinout-B (VSS/VDD/OUT/Input), supports SENT 3µs mode with built-in capacitors, and is configured for legacy angular/linear applications (-303 option code). It integrates a 24 MHz main clock (±5% drift), 1 MHz watchdog clock, and failsafe state activation within 11.9–34.6 ms after digital fault detection.
Key Specifications
| Parameter | Value and Actual Design Meaning |

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-SP | Same DMP-4 Pinout-B package and -300 legacy option code; differs only in trim/form (STD1 1.27 vs STD2 2.54). | Identical angular/linear position functionality; same SENT/PWM interface and accuracy spec. | Select ACE-300 for standard 1.27 mm pitch; ACE-303 specifies STD2 2.54 mm trim/form for improved mechanical mounting rigidity. |
| MLX90371GVS-ACE-303-SP | Single-die predecessor with identical DMP-4 Pinout-B and -303 option; lacks dual diagnostics and ASIL-C certification. | Supports same legacy applications but not suitable for ASIL-B/C systems requiring certified safety mechanisms. | Use only in non-safety-critical industrial position sensing where cost sensitivity outweighs functional safety requirements. |
Compared with MLX90372GVS-ACE-303-SP, ACE-300 offers identical electrical behavior but different mechanical trim, while MLX90371GVS-ACE-303-SP omits ASIL-C diagnostics and failsafe state-making it unsuitable for automotive safety architectures despite matching pinout and output protocol.

The MLX90372GVS-ACE-303-SP uses the DMP-4 (Dual Mould Package) with Pinout-B configuration: Pin 1 = OUT, Pin 2 = VSS, Pin 3 = VDD, Pin 4 = Input (NTC/gateway). This PCB-less package integrates decoupling capacitance and supports direct magnet mounting in high-vibration environments.
Does MLX90372GVS-ACE-303-SP support both SENT and PWM outputs?
Yes, MLX90372GVS-ACE-303-SP supports both SENT (SAE J2716 APR2016) and PWM outputs, selectable via end-user programming. Factory default is SENT 3µs mode; PWM mode provides pulse-width modulated position data compatible with legacy analog-input ECUs.
What safety certifications apply to MLX90372GVS-ACE-303-SP?
MLX90372GVS-ACE-303-SP is certified to ISO26262 ASIL-C as a Safety Element out of Context (SEooC) and qualified to AEC-Q100 Grade 0. These certifications validate its use in safety-critical automotive systems such as electronic throttle control and brake-by-wire.
How does the -303 option code differ from other MLX90372 variants?
The -303 option code indicates Legacy / Angular Rotary / Linear position configuration with STD2 2.54 mm trim-and-form in DMP-4 package. It enables standard position decoding (not stray-field immune) and matches the electrical behavior of -300, differing only in mechanical footprint and mounting rigidity.
Can MLX90372GVS-ACE-303-SP operate directly from a 12 V battery supply?
Yes, MLX90372GVS-ACE-303-SP supports battery-supply operation (6–18 V) with internal regulation. The WARM_ACT_HIGH parameter selects battery mode, enabling undervoltage lockout at 3.9 V and overvoltage protection up to 24.5 V-critical for automotive 12 V system compatibility.
