Product details
Overview
MLX90372GDC-ACE-100-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 per SAE J2716 APR2016, operates from -40°C to +160°C, consumes 9.0–12.6 mA, and uses SOIC-8 package with integrated signal conditioning and DSP for robust non-contact angular measurement in automotive throttle and pedal systems.
For engineers reviewing the MLX90372GDC-ACE-100-RE datasheet, pinout, applications, or equivalent options, this page provides verified functional context, SOIC-8 pin mapping, stray-field-immune accuracy specs, SENT/PWM output configuration options, and AEC-Q100/ISO26262 ASIL-C safety implementation details.
Technical Context
The MLX90372GDC-ACE-100-RE implements Triaxis® Hall sensing to measure Bx, By, and Bz magnetic field components simultaneously, enabling high-accuracy absolute angle decoding without mechanical contact. Its on-chip DSP supports programmable piecewise linear (PWL) transfer characteristics-up to 32 points-and configurable SENT frame structure with 48-bit ID support.
This variant is factory-configured for Angular Rotary Strayfield Immune operation (-100 option code), optimized for low-field magnetic environments with enhanced immunity to external stray fields. It uses a single-die SOIC-8 package and supports both SENT (3 µs tick) and PWM output modes via end-user programming, with built-in diagnostics including intelligent watchdog (TIWD = 19–21 ms) and analog/digital diagnostic cycle times.

Equivalent & Alternatives
The following parts are listed as comparable options for similar magnetic position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90371GDC-ABF-100-RE | Legacy Triaxis® device with fixed 16-point PWL; no SENT v2.0 support; lower diagnostic coverage | Limited to legacy designs requiring backward compatibility; lacks ASIL-C SEooC documentation | Select only for cost-sensitive, non-safety-critical industrial applications where SENT v1.0 suffices |
| AMS AS5055A-BQFT | 14-bit SPI-output magnetic encoder; no integrated SENT; requires external MCU for protocol handling | Requires additional microcontroller resources and PCB area; not AEC-Q100 qualified | Consider only for non-automotive embedded systems needing higher resolution but accepting added software overhead |
Compared with MLX90372GDC-ACE-100-RE, the MLX90371 offers reduced safety compliance and older protocol support, while the AS5055A demands external processing and lacks automotive qualification - making the MLX90372GDC-ACE-100-RE the optimal choice for new ASIL-B/C automotive designs requiring integrated SENT and stray-field resilience.

FAQ
What is the primary magnetic sensing architecture used in the MLX90372GDC-ACE-100-RE?
The MLX90372GDC-ACE-100-RE employs Melexis' proprietary Triaxis® Hall technology, which measures all three orthogonal components (Bx, By, Bz) of the applied magnetic flux density. This enables precise absolute angular position calculation without mechanical contact or external magnetic concentrators, and is specifically calibrated in the -100 variant for stray-field-immune rotary applications.
Does the MLX90372GDC-ACE-100-RE support both SENT and PWM output modes?
Yes, the MLX90372GDC-ACE-100-RE supports both SENT (SAE J2716 APR2016 compliant) and PWM output modes, selectable via end-user programming. The default factory configuration uses SENT with 3 µs tick timing, but PWM can be enabled to provide a duty-cycle-modulated signal compatible with legacy ECUs lacking SENT receivers.
What safety certifications apply to the MLX90372GDC-ACE-100-RE?
The MLX90372GDC-ACE-100-RE is certified as an ISO26262 ASIL-C Safety Element out of Context (SEooC) and qualified to AEC-Q100 Grade 0. These certifications confirm its suitability for integration into ASIL-B and ASIL-C automotive systems, with documented safety mechanisms including dual watchdogs, memory ECC, and diagnostic cycle timers.
What package type and pin count does the MLX90372GDC-ACE-100-RE use?
The MLX90372GDC-ACE-100-RE uses an 8-pin SOIC-8 package (Package Code DC), RoHS-compliant and rated for operation from -40°C to +160°C. Pinout includes dedicated VDD, VSS (digital and analog), OUT, VDEC, and internally grounded Input/Test terminals - with NC pin tied to ground per EMC guidelines.
How is stray-field immunity implemented in the MLX90372GDC-ACE-100-RE?
Stray-field immunity in the MLX90372GDC-ACE-100-RE is achieved through factory-programmed magnetic front-end calibration specific to the -100 option code (Angular Rotary Strayfield Immune – Low Field Variant). This includes optimized gain settings, differential signal processing, and algorithmic rejection of orthogonal interference fields - validated per IEC 61000-4-8 testing protocols.
