Product details
Overview
MLX90372GVS-ACE-308-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, supports programmable 4–32-point piecewise linear transfer characteristics, and features ISO26262 ASIL-C safety compliance for automotive applications such as throttle and steering wheel position sensing.
For engineers reviewing the MLX90372GVS-ACE-308-RE datasheet, pinout, applications, or equivalent options, key selection criteria include DMP-4 package compatibility, SENT 3µs mode configuration (ACE-308), stray-field immune operation in legacy angular/linear mode, and built-in decoupling capacitor support per section 15.3.
Technical Context
The MLX90372GVS-ACE-308-RE implements Triaxis® sensing architecture that simultaneously measures Bx, By, and Bz magnetic field components to compute absolute angle or linear displacement. Its on-chip DSP enables real-time signal conditioning, including configurable FIR filtering and exponential moving average (EMA) noise suppression.
This variant uses the DMP-4 package with Pinout-B (VSS/VDD/OUT/Input), supports SENT SAE J2716 APR2016 with Secure Sensor format (48-bit ID option), and is factory-configured for ACE-308 - meaning STD4 2.54 mm trim & form, SENT 3µs mode, and standard angular/linear legacy application mode (-300).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Temp | -40°C to +160°C - qualified for under-hood automotive environments without external thermal derating. |
| Supply Voltage | 4.5 V to 5.5 V (regulated) or 6 V to 18 V (battery) - dual-mode supply supports direct battery connection with overvoltage protection at 21.5–24.5 V. |
| Output Interface | SENT (SAE J2716 APR2016) or PWM - SENT frame includes CRC, diagnostics, and user-defined values; PWM duty cycle encodes position. |
| Accuracy | ±0.3° typical angular error in legacy mode - specified per Table 9.5 for ACE-300/308 variants under defined magnetic circuit conditions. |
| Package | DMP-4 (PCB-less dual mold), Pinout-B - 4-pin surface-mount with integrated capacitors, STD4 2.54 mm trim & form (section 18.13). |
| Safety Certification | ISO26262 ASIL-C Safety Element out of Context - enables integration into ASIL-B/C systems with appropriate system-level decomposition. |
| Stray-Field Immunity | Legacy mode (-300) - optimized for standard angular/linear applications without enhanced stray-field rejection (unlike -100/-200 variants). |
Pinout & Package
DMP-4 package (PCB-less dual mold) with Pinout-B configuration: compact 4-pin surface-mount footprint supporting direct magnet coupling and built-in decoupling capacitance per section 15.3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT | Digital output terminal for SENT or PWM signal - push-pull or open-drain configurable; supports pull-up to 18 V. |
| 2 | VSS | Analog/digital ground reference - must be connected to low-impedance PCB ground plane for EMC robustness. |
| 3 | VDD | Main supply input - accepts regulated 4.5–5.5 V or battery 6–18 V; internal regulator generates 3.3 V analog rail (VDEC). |
| 4 | Input | NTC or analog/digital gateway input - used for temperature compensation or auxiliary sensor interface; voltage range -3 V to +6 V. |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® 3D Hall Sensing | Simultaneous Bx/By/Bz measurement enables true absolute position decoding without mechanical cams or gears. |
| Programmable Transfer Curve | Up to 32-point piecewise linear (PWL) mapping allows precise calibration to non-linear mechanical motion profiles. |
| SENT Secure Sensor Format | Includes embedded CRC, diagnostic flags, and 48-bit unique ID - supports traceability and fault detection in safety-critical ECUs. |
| DMP-4 Integrated Capacitors | Built-in decoupling eliminates external capacitors (section 15.3), reducing BOM count and PCB area in space-constrained modules. |
| AEC-Q100 Grade 0 | Qualified for automotive use up to +160°C ambient - validated for engine bay, transmission, and chassis applications. |

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 STD1 1.27 mm trim & form (not STD4); identical SENT 3µs mode and legacy -300 application config. | No functional difference in sensing or output - differs only in mechanical footprint and capacitor layout per section 18.9 vs 18.13. | Select ACE-300 if legacy PCB layout uses 1.27 mm pitch; ACE-308 requires updated stencil and placement for 2.54 mm STD4 form factor. |
| MLX90371GVS-ACE-308-RE | Single-die predecessor with identical DMP-4 Pinout-B and ACE-308 coding, but lacks ISO26262 ASIL-C certification and advanced diagnostics (no Secure Sensor SENT). | Not suitable for ASIL-B/C systems; limited to non-safety-critical linear/rotary sensing where cost is prioritized over functional safety. | Choose MLX90371 only for cost-sensitive industrial applications without automotive safety requirements. |
Compared with MLX90372GVS-ACE-300-RE, the MLX90372GVS-ACE-308-RE offers identical electrical performance but mandates updated PCB assembly for STD4 2.54 mm trim; versus MLX90371GVS-ACE-308-RE, it adds ASIL-C compliance, enhanced SENT diagnostics, and improved stray-field tolerance in legacy mode.

FAQ
What is the package type and pin configuration of MLX90372GVS-ACE-308-RE?
The MLX90372GVS-ACE-308-RE uses the DMP-4 (Dual Mould Package) with Pinout-B configuration: pins are OUT, VSS, VDD, and Input in that order. This matches section 3.4 of the datasheet and supports built-in decoupling capacitors per section 15.3. The "VS" in the part number explicitly denotes the DMP-4 package, and ACE-308 specifies STD4 2.54 mm trim & form.
Does MLX90372GVS-ACE-308-RE support both SENT and PWM outputs?
Yes, MLX90372GVS-ACE-308-RE supports both SENT (SAE J2716 APR2016) and PWM output modes. It is factory-configured for SENT 3µs mode per ACE-308 coding, but end users can reprogram it to PWM via the MLX90372 programming interface described in section 12. The output stage supports push-pull or open-drain drive with configurable load conditions.
What safety certifications apply to MLX90372GVS-ACE-308-RE?
MLX90372GVS-ACE-308-RE is certified to ISO26262 ASIL-C as a Safety Element out of Context (SEooC) and qualified to AEC-Q100 Grade 0. These certifications are documented in sections 14 and 2 of the datasheet. The device provides hardware-level safety mechanisms including watchdog timers (IWD/AWD), memory ECC, and diagnostic cycles - all active in the ACE-308 configuration.
How does the MLX90372GVS-ACE-308-RE achieve stray-field immunity?
The MLX90372GVS-ACE-308-RE operates in legacy mode (-300), which provides baseline stray-field resilience through Triaxis® 3D sensing and on-chip signal processing, but not the enhanced immunity of -100/-200 variants. Its differential front-end and digital filtering suppress common-mode interference, and the DMP-4 package's magnetic shielding further improves robustness - confirmed in section 8.4 and figure 2 of the datasheet.
Can MLX90372GVS-ACE-308-RE be programmed in-system?
Yes, MLX90372GVS-ACE-308-RE supports in-system programming via its Input pin (Pin 4 in DMP-4 Pinout-B) using Melexis' standard UART-based protocol. Users can configure output mode, transfer characteristic (up to 32-point PWL), filtering, diagnostics, and identification fields without removing the device from the PCB - detailed in sections 12 and 13.3 of the datasheet.
