Product details
Overview
MLX90372GVS-ACE-303-RE 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 certification, and uses a PCB-less DMP-4 package with Pinout-B configuration for compact automotive sensor modules.
For engineers reviewing the MLX90372GVS-ACE-303-RE datasheet, pinout, applications, or equivalent options, this page provides verified functional context, DMP-4 Pinout-B terminal roles, SENT/PWM timing compliance (SAE J2716 APR2016), stray-field robustness in legacy mode, and direct alternative part guidance for pedal, throttle, and steering wheel position systems.
Technical Context
The MLX90372GVS-ACE-303-RE implements a Triaxis® Hall front end sensitive to Bx, By, and Bz magnetic field components, enabling absolute angle or linear displacement decoding via on-chip DSP and analog signal conditioning. Its DMP-4 package (Pinout-B) integrates an Input pin for NTC or analog/digital gateway functions, supporting system-level diagnostics and temperature compensation.
This variant uses ACE chip revision with option code -303: legacy angular/linear mode (-3xx), DMP-4 Pinout-B configuration (-0xx), and STD2 2.54 mm trim & form (-x3). It supports SENT 3µs mode with built-in capacitors and operates across 4.5–5.5 V (regulated) or 6–18 V (battery), with supply current of 8.0–10.5 mA at -40°C to +160°C.
Key Specifications

|---|---|
| Operating Temp | -40°C to +160°C - Validated for under-hood automotive environments without derating. |
| Supply Voltage | 4.5–5.5 V (regulated) or 6–18 V (battery) - Dual-mode operation enables direct battery connection in vehicle power domains. |
| Supply Current | 8.0–10.5 mA - Enables low-power operation in always-on sensor applications like ride height monitoring. |
| Output Protocol | SENT (SAE J2716 APR2016) or PWM - Configurable via programming; SENT supports error codes and user-defined values. |
| Magnetic Sensing | Bx, By, Bz triaxial detection - Enables absolute position measurement without mechanical contact or potentiometer wear. |
| Safety Certification | ISO26262 ASIL-C Safety Element out of Context - Supports integration into ASIL-B/C system architectures without additional hardware redundancy. |
| Package | DMP-4, Pinout-B, STD2 2.54 mm - PCB-less dual-mold package reduces assembly cost and footprint; Input pin enables NTC integration. |
Pinout & Package
DMP-4 (PCB-less dual mold) package with Pinout-B configuration, optimized for compact, high-reliability automotive sensors. Dimensions per STD2 2.54 mm trim & form (Section 18.11).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT | SENT or PWM output signal - Drives ECU input directly; supports open-drain or push-pull modes per configuration. |
| 2 | VSS | Analog/digital ground reference - Shared ground plane required for noise immunity in high-EMC environments. |
| 3 | VDD | Primary supply input - Accepts regulated 4.5–5.5 V or battery 6–18 V; internal regulation generates 3.3 V analog rail. |

| Stray-field immunity (legacy mode) | Validated performance in -300/-303 configurations - Maintains accuracy in proximity to motors, solenoids, or high-current traces. |
| SENT Secure Sensor format | Embedded CRC, error flags, and user-defined payload - Reduces ECU-side validation overhead and supports diagnostic traceability. |
| Dual supply mode | Configurable 5 V regulated or 6–18 V battery operation - Eliminates need for external LDO in 12 V vehicle architectures. |
Applications
| Throttle Position Sensing | Pedal Position Sensing |
|---|---|
|
Use Scenario: Real-time detection of accelerator pedal angle in gasoline/diesel powertrains for engine torque control. IC Role / Device Role / Timing Role: Absolute rotary position processor delivering SENT frames at 100 Hz with <10 µs jitter for closed-loop fuel mapping. Use Value: Eliminates potentiometer wear and contact bounce; ASIL-C compliance enables direct integration into powertrain control units. |
Use Scenario: Monitoring brake or clutch pedal travel in electronic braking systems (EBS) and automated manual transmissions. IC Role / Device Role / Timing Role: Linear position sensor with programmable PWL transfer function, outputting SENT frames synchronized to vehicle CAN bus timing. Use Value: Enables fail-operational redundancy via dual-die alternatives while maintaining same DMP-4 footprint for design reuse. |
| Steering Wheel Position Sensing | Ride Height Position Sensing |
|

IC Role / Device Role / Timing Role: Rotary position processor with stray-field immunity, operating in legacy mode (-303) to reject interference from EPS motor currents. Use Value: Achieves ±0.5° accuracy over lifetime without recalibration; DMP-4 package withstands vibration and thermal cycling in column-mounted assemblies. |
Use Scenario: Detecting suspension compression/expansion in adaptive air suspension systems for automatic ride leveling. IC Role / Device Role / Timing Role: Linear position sensor with SENT output, interfacing directly with body control module (BCM) via dedicated sensor bus. Use Value: Replaces LVDTs with lower cost, smaller size, and higher reliability; operates continuously at 160°C ambient near exhaust components. |
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-RE | Same DMP-4 Pinout-B package and ACE revision, but -300 option code lacks Pinout-B-specific configuration bits for Input pin use. | Supports legacy angular/linear mode but does not enable NTC gateway functionality on Pin 4. | Select when NTC integration is unnecessary and factory-default SENT timing suffices. |
| MLX90372GGO-ACE-300-RE | TSSOP-16 dual-die package with full redundancy; isolation resistance >4 MΩ between dice; supply current ~2× higher (16–21 mA). | Required for ASIL-D system decomposition or where hardware redundancy is mandated by OEM safety architecture. | Choose for full fault-tolerant designs where DMP-4 footprint cannot be retained and PCB space allows TSSOP-16. |
Compared with MLX90372GVS-ACE-303-RE, the -300 variant omits Pinout-B Input pin functionality, while the GO package adds hardware redundancy at the cost of doubled current draw and larger footprint-making the -303 optimal for cost-sensitive, space-constrained ASIL-C applications requiring NTC support.

FAQ
What is the package type and pin configuration of MLX90372GVS-ACE-303-RE?
The MLX90372GVS-ACE-303-RE 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 matches STD2 2.54 mm trim & form per datasheet Section 18.11 and enables compact, PCB-less integration in automotive sensor housings.
Does MLX90372GVS-ACE-303-RE support both SENT and PWM output protocols?
Yes, MLX90372GVS-ACE-303-RE supports both SENT (SAE J2716 APR2016 compliant) and PWM output modes, configurable via end-user programming. SENT mode delivers secure frames with CRC, error flags, and user-defined data; PWM mode provides duty-cycle-modulated position signals compatible with legacy ECU inputs.
What is the meaning of the option code "ACE-303" in MLX90372GVS-ACE-303-RE?
In MLX90372GVS-ACE-303-RE, "ACE" denotes the preferred chip revision, and "303" breaks down as: "3" = legacy angular/linear position mode, "0" = DMP-4 Pinout-B configuration (supporting Input pin functionality), and "3" = STD2 2.54 mm trim & form. This ensures compatibility with NTC integration and specified mechanical mounting dimensions.
Is MLX90372GVS-ACE-303-RE qualified for automotive applications?
Yes, MLX90372GVS-ACE-303-RE is AEC-Q100 qualified and certified to ISO26262 ASIL-C as a Safety Element out of Context. It operates across -40°C to +160°C, supports battery voltage ranges up to 18 V, and includes built-in diagnostics such as watchdog timers and supply monitoring for automotive-grade reliability.
How does the Input pin (Pin 4) function in MLX90372GVS-ACE-303-RE?
In MLX90372GVS-ACE-303-RE's DMP-4 Pinout-B configuration, Pin 4 serves as an Input terminal for NTC thermistors or analog/digital gateway signals. This enables real-time temperature compensation of magnetic measurements or transmission of auxiliary sensor data without external circuitry, reducing BOM count and board area.
