Product details
Overview
MLX90372GVS-ACE-103-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 per SAE J2716 APR2016, operates from -40°C to +160°C, features ISO26262 ASIL-C safety compliance as a Safety Element out of Context, and uses the PCB-less DMP-4 package with Pinout-B configuration (VSS/VDD/OUT/Input).
For engineers reviewing the MLX90372GVS-ACE-103-SP datasheet, pinout, applications, or equivalent options, this page provides verified functional context, validated DMP-4 Pinout-B terminal roles, confirmed stray-field-immune angular rotary operation, and real-world automotive sensor design considerations including SENT timing, NTC gateway support, and thermal robustness up to 160°C.
Technical Context
The MLX90372GVS-ACE-103-SP implements a Triaxis® Hall front end sensitive to Bx, By, and Bz magnetic field components, enabling high-accuracy absolute angle decoding from 0° to 360° using external magnet assemblies. Its on-chip DSP performs real-time signal conditioning, piecewise linear (PWL) transfer function mapping, and SENT frame encoding with error codes and user-defined values.
This variant is configured for Angular Rotary Strayfield Immune mode (Option Code -103), uses the DMP-4 Pinout-B package (Input pin enabled for NTC or analog/digital gateway functions), and supports SENT 3µs timing with built-in decoupling capacitors - eliminating external passive components in the signal path.

Pinout & Package
DMP-4 (Dual Mould Package) is a PCB-less, surface-mount package with molded leads and integrated decoupling capacitors. Pinout-B configuration enables the Input pin for NTC thermistor interface or analog/digital gateway functionality - critical for temperature compensation and multi-sensor integration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Digital output driver | SENT or PWM signal output; push-pull or open-drain configurable; supports pull-up to 5–18 V. |
| 2 (VSS) | Analog/digital ground reference | Common return for supply and signal paths; must be connected to low-impedance system ground. |
| 3 (VDD) | Power 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) | Configurable analog/digital input | Supports NTC thermistor biasing, analog voltage monitoring, or digital gateway signals - used for temperature compensation in rotary applications. |
Key Features
| Feature | Design Value |
|---|---|

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 | Single-die architecture; no ASIL-C certification; SENT-only output (no PWM); lower accuracy (±0.5° typ). | Limited to non-safety-critical linear/rotary applications; lacks Input pin for NTC integration. | Select when cost sensitivity outweighs functional safety and temperature compensation needs. |
| TLV493DW2B6HTSA1 | 3D Hall sensor with I²C output; no SENT/PWM; no ASIL-C; -40°C to +125°C rating; SOIC-8 package. | Suitable for consumer/industrial position sensing only; requires external microcontroller for protocol translation and diagnostics. | Choose for space-constrained I²C-based designs where SENT infrastructure is unavailable. |
Compared with MLX90372GVS-ACE-103-SP, the MLX90371 offers reduced safety assurance and no NTC gateway, while the TLV493DW2B6HTSA1 lacks automotive temperature range, SENT compliance, and ASIL-C support - making MLX90372GVS-ACE-103-SP the only option meeting full AEC-Q100 Grade 0 and ISO26262 ASIL-C requirements for stray-field-immune rotary sensing.

FAQ
What is the operating temperature range of the MLX90372GVS-ACE-103-SP?
The MLX90372GVS-ACE-103-SP is rated for operation from -40°C to +160°C, fully compliant with AEC-Q100 Grade 0 requirements. This extended range enables reliable deployment in under-hood locations such as throttle bodies, transmission shifters, and suspension modules where ambient temperatures exceed 125°C.
Does the MLX90372GVS-ACE-103-SP support both SENT and PWM output modes?
The MLX90372GVS-ACE-103-SP supports SENT output per SAE J2716 APR2016 as standard; PWM output is programmable but not factory-default for this -103 variant. Configuration requires Melexis' PTC software and compatible programming hardware - SENT remains the recommended and validated interface for ASIL-C applications.
What is the function of the Input pin on the MLX90372GVS-ACE-103-SP DMP-4 Pinout-B package?
The Input pin on the MLX90372GVS-ACE-103-SP serves as a configurable analog/digital gateway: it supports NTC thermistor biasing for temperature compensation, analog voltage monitoring, or digital signal injection. In rotary position applications, it enables real-time thermal correction of magnetic drift without external circuitry.
Is the MLX90372GVS-ACE-103-SP pin-compatible with earlier MLX90372 revisions?
The MLX90372GVS-ACE-103-SP uses DMP-4 Pinout-B, which is not pin-compatible with SOIC-8 or TSSOP-16 variants. However, it maintains functional equivalence with other ACE-revision MLX90372 devices. Migration from ACC or earlier ACE versions requires layout revision due to differing package geometry and terminal assignment.
How does the stray-field immunity of the MLX90372GVS-ACE-103-SP improve system reliability?
The MLX90372GVS-ACE-103-SP's stray-field immunity (validated per -100 code spec) rejects magnetic interference up to ±1 T from adjacent motors, solenoids, or wiring harnesses. This ensures consistent angular accuracy in throttle, pedal, and steering applications - eliminating false-trigger events and reducing ECU diagnostic false positives in safety-critical systems.
