Product details
Overview
MLX90372GVS-ACE-100-SP 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, draws 9.0–12.6 mA supply current, and uses a PCB-less DMP-4 package with Pinout-A. It enables non-contacting throttle and steering wheel position sensing in automotive powertrain and chassis systems.
For engineers reviewing the MLX90372GVS-ACE-100-SP datasheet, pinout, applications, or equivalent options, key selection criteria include its angular stray-field immunity (-100 option code), SENT 3µs timing mode, DMP-4 STD1 1.27 trim & form configuration, and AEC-Q100 qualification for automotive use.
Technical Context
The MLX90372GVS-ACE-100-SP implements a Triaxis® Hall front end sensitive to Bx, By, and Bz magnetic field components, enabling robust absolute angle decoding without mechanical wear. Its on-chip DSP performs real-time signal conditioning, including programmable piecewise linear (PWL) transfer characteristics with up to 32 points and configurable filtering.
It supports SENT output with Secure Sensor format encoding (48-bit ID optional), error codes, and user-defined values; PWM output is selectable via programming. The device integrates dual watchdogs (IWD/AWD), undervoltage/overvoltage detection, and PTC protection - all aligned with ISO 26262 ASIL-C safety requirements as a Safety Element out of Context.
Key Specifications

| Package | DMP-4 (Pinout-A) - PCB-less dual-mold package with 4 terminals (VSS/VDD/OUT/VSS), reducing system cost and footprint. |
Pinout & Package
DMP-4 package (PCB-less dual mold) with Pinout-A: compact 4-terminal surface-mount configuration designed for direct integration into molded housings or sensor assemblies. No PCB required; terminals are formed for solder or press-fit mounting.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VSS | Analog/digital ground reference; must be connected to system ground for stable bias and EMC performance. |
| 2 | VDD | Main supply input (4.5–5.5 V); internal regulator generates 3.3 V analog rail (VDEC). |
| 3 | OUT | SENT/PWM output driver; push-pull capable; supports open-drain configuration with external pull-up. |

| Programmable PWL Transfer | Up to 32-point piecewise linear calibration - supports custom mechanical linkage compensation and non-linear actuator response. |
| SENT Secure Sensor Format | Embedded CRC, status flags, and 48-bit ID - enables traceability, fault isolation, and secure ECU-level diagnostics in ASIL-B/C systems. |
| AEC-Q100 Grade 0 | Qualified per AEC-Q100 Rev G - validated for automotive life cycles including temperature cycling, humidity, and mechanical shock. |
Applications
| Throttle Position Sensing | Pedal Position Sensing |
|---|---|
Use Scenario: Monitoring accelerator pedal angle in gasoline/diesel powertrains for precise air-fuel ratio and torque control. IC Role / Device Role / Timing Role: Absolute rotary position processor delivering SENT frames every 960 µs (two-angle synchronous mode) with <20 ms watchdog timeout. Use Value: ±0.3° accuracy and stray-field immunity ensure consistent throttle mapping despite proximity to starter motor EMI. | Use Scenario: Detecting brake or accelerator pedal displacement in electronic braking and drive-by-wire systems. IC Role / Device Role / Timing Role: Linear-to-rotary position transducer using integrated IMC; outputs SENT with diagnostic status flags per frame. Use Value: DMP-4 package enables direct integration into pedal assembly housing - no PCB, no connectors, reduced BOM cost. |
| Steering Wheel Angle Sensing | Ride Height Control |
Use Scenario: Measuring absolute steering angle for EPS assist, lane-keeping, and stability control algorithms. IC Role / Device Role / Timing Role: High-reliability rotary sensor with dual watchdogs and ASIL-C safety mechanisms; SENT output synchronized to vehicle CAN bus timing.

IC Role / Device Role / Timing Role: Absolute linear position sensor using off-axis magnet configuration; SENT output includes temperature-compensated raw angle data. Use Value: Programmable transfer characteristic compensates for nonlinear spring rate and lever geometry - improves height control resolution by >3× vs fixed-gain sensors. |
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-ABF-100-SP | Legacy Triaxis® device; single-die architecture; no ASIL-C support; SENT only (no PWM option); lower accuracy (±0.5°) | Limited to non-safety-critical linear/rotary sensing; lacks diagnostic coverage for ASIL-B systems | Select only for cost-sensitive legacy designs where functional safety certification is not required. |
| AMS AS5055A-BQFT | 360° contactless angle sensor; SPI/I²C interface; no SENT output; ±0.15° typical accuracy; requires external MCU for diagnostics | Requires host processor for protocol translation and safety monitoring; unsuitable for direct ECU connection in SENT-only architectures | Prefer when SPI interface and highest angular resolution are prioritized over automotive serial bus compatibility and integrated safety features. |
Compared with MLX90371GVS-ABF-100-SP and AMS AS5055A-BQFT, the MLX90372GVS-ACE-100-SP uniquely combines SENT compliance, ASIL-C readiness, stray-field immunity, and DMP-4 integration - making it the only drop-in solution for new AEC-Q100-compliant throttle and pedal modules requiring zero-PCB design.

FAQ
What is the operating temperature range of the MLX90372GVS-ACE-100-SP?
The MLX90372GVS-ACE-100-SP is rated for continuous operation from -40°C to +160°C, meeting AEC-Q100 Grade 0 requirements. This range covers under-hood automotive locations such as throttle bodies, transmission shifters, and suspension control arms where ambient temperatures exceed 125°C.
Does the MLX90372GVS-ACE-100-SP support both SENT and PWM output modes?
Yes, the MLX90372GVS-ACE-100-SP supports both SENT (SAE J2716 APR2016) and PWM output protocols, but only one can be active at a time. SENT is factory-default; PWM mode is enabled via end-user programming using Melexis' PTM software and compatible programming hardware.
What does the "-100" in MLX90372GVS-ACE-100-SP signify?
The "-100" suffix denotes the Rotary Stray-field Immune – Low Field Variant configuration. It specifies optimized magnetic sensitivity and internal compensation for applications requiring immunity to orthogonal stray fields up to ±1 T, such as throttle position sensing near starter motors or alternators.
Is the DMP-4 package of the MLX90372GVS-ACE-100-SP lead-free and RoHS-compliant?
Yes, the DMP-4 package used in the MLX90372GVS-ACE-100-SP is RoHS-compliant and lead-free, as confirmed in the official Melexis datasheet revision 8 (March 2019). It meets JEDEC J-STD-020 moisture sensitivity level MSL3 and supports standard reflow profiles.
Can the MLX90372GVS-ACE-100-SP be programmed in-system after soldering?
Yes, the MLX90372GVS-ACE-100-SP supports in-system programming via its Input pin (Pin 4 in DMP-4 Pinout-B) or through dedicated test pins in SOIC-8/TSSOP-16 packages. Programming requires Melexis PTM software, a compatible programmer (e.g., EVK-PTM), and correct voltage sequencing per section 12 of the datasheet.
