Product details
Overview
MLX90372GVS-ACE-103-RE 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 compliant with SAE J2716 APR2016, operates from -40°C to +160°C, consumes 9.0–12.6 mA supply current, and integrates on-chip DSP for robust angle decoding in automotive throttle and steering wheel applications.
For engineers reviewing the MLX90372GVS-ACE-103-RE datasheet, pinout, applications, or equivalent options, this page provides verified package mapping (DMP-4 Pinout-B), confirmed stray-field immunity for angular rotary use, SENT timing compliance, functional safety ASIL-C classification, and validated alternative options for high-reliability automotive sensor design.
Technical Context
The MLX90372GVS-ACE-103-RE implements Triaxis® sensing architecture that measures all three orthogonal magnetic field components (Bx, By, Bz) to compute absolute angular position without mechanical contact. Its dual-die isolation is not applicable-this variant uses single-die DMP-4 packaging with built-in capacitors and Pinout-B configuration (OUT/VSS/VDD/Input).
It supports SENT 3 µs mode with programmable frame structure and includes integrated diagnostics (Intelligent Watchdog timeout: 19–21 ms), configurable transfer characteristics (PWL up to 32 points), and robust EMC behavior via grounded unused pins. The -103 option code specifies Angular Rotary Strayfield Immune operation with low-field variant calibration and STD2 2.54 mm trim/form.

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute magnetic position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90372GVS-ACE-100-RE | Same DMP-4 Pinout-B package and -100 code: Angular Rotary Strayfield Immune Low Field Variant, STD1 1.27 mm trim/form | Identical functional scope but differs in mechanical footprint and internal capacitor configuration | Select when legacy board layout uses STD1 1.27 mm lead pitch and standard capacitor implementation |
| MLX90372GVS-ACE-101-RE | Same DMP-4 Pinout-B package and -101 code: Angular Rotary Strayfield Immune Low Field Variant, STD1 2.54 mm trim/form (capacitor config #2) | Matches mechanical envelope of ACE-103 but uses alternate internal capacitor network for EMI filtering | Choose for enhanced EMC performance in high-noise chassis domains where capacitor configuration #2 improves noise rejection |
Compared with MLX90372GVS-ACE-103-RE, ACE-100 offers identical sensing and safety features but requires different PCB land pattern due to STD1 1.27 mm lead spacing, while ACE-101 shares the same STD2 2.54 mm footprint but modifies internal capacitor topology to improve transient immunity-neither is pin-compatible without layout revision.

Does MLX90372GVS-ACE-103-RE support SENT or PWM output?
MLX90372GVS-ACE-103-RE supports both SENT and PWM output modes, but is factory-configured for SENT 3 µs mode per SAE J2716 APR2016. The Output pin delivers secure SENT frames with CRC, diagnostic flags, and 48-bit ID. PWM mode is user-programmable via EEPROM and supports duty-cycle modulation for analog-like interface in legacy systems.
What functional safety level does MLX90372GVS-ACE-103-RE achieve?
MLX90372GVS-ACE-103-RE is certified as an ISO 26262 ASIL-C Safety Element out of Context (SEooC). It includes integrated diagnostics such as Intelligent Watchdog (19–21 ms timeout), configurable diagnostic cycle times, and hardware-level error detection-enabling its use as a safety-critical component in ASIL-B or ASIL-C automotive systems when integrated per Melexis safety manual.
How does the stray-field immunity of MLX90372GVS-ACE-103-RE benefit automotive applications?
The stray-field immunity of MLX90372GVS-ACE-103-RE is calibrated for Angular Rotary Low Field Variant (-100 series), allowing accurate 0–360° position measurement even in magnetically noisy environments-such as near electric motors, solenoids, or high-current cables in throttle bodies or steering columns-without external shielding or recalibration.
Can MLX90372GVS-ACE-103-RE interface with an NTC thermistor?
Yes, MLX90372GVS-ACE-103-RE supports NTC thermistor interfacing via its Input pin (Pin 4 in DMP-4 Pinout-B). This enables real-time temperature compensation of magnetic transfer characteristics, improving angular accuracy across the full -40°C to +160°C operating range-critical for precision applications like electronic throttle control and EPS.
