Product details
Overview
MLX90372GVS-ACE-301-SP from Melexis is a monolithic Triaxis® Hall-based magnetic position processor IC in DMP-4 package (Pinout-B), delivering absolute rotary or linear position sensing with SENT 3µs output, ±0.5° angular accuracy in legacy mode, and operation from −40°C to +160°C. It decodes Bx/By/Bz magnetic field components for non-contacting throttle, pedal, and steering wheel position sensing in automotive powertrain and chassis systems.
For engineers reviewing the MLX90372GVS-ACE-301-SP datasheet, pinout, applications, or equivalent options, key selection factors include its DMP-4 Pinout-B configuration with integrated Input terminal for NTC/analog gateway, SENT compliance per SAE J2716 APR2016, ISO26262 ASIL-C safety element out of context, AEC-Q100 qualification, and programmable piecewise linear transfer characteristic.
Technical Context
The MLX90372GVS-ACE-301-SP implements a Triaxis® Hall front end with integrated magnetic concentrator, 12-bit ADC, DSP-based signal conditioning, and SENT/PWM output stage. Its DMP-4 Pinout-B configuration assigns Pin 4 as Input for NTC or analog/digital gateway functions, enabling temperature compensation or auxiliary sensor integration without external circuitry.
This variant operates in Standard/Legacy Mode (−300 option code), supports SENT 3µs timing with configurable frame structure, and delivers angle measurements at 588 µs typical acquisition period in asynchronous mode. Internal diagnostics include intelligent watchdog (20 ms timeout) and programmable error reporting via SENT secure sensor format.

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-SP | Same DMP-4 Pinout-B package and −300 legacy mode, but uses standard capacitor configuration (vs. config #2 in −301). | No Input terminal functionality - lacks NTC/gateway capability on Pin 4. | Select −300 when temperature compensation is handled externally or not required. |
| MLX90372GVS-ACE-200-SP | Same DMP-4 package but configured for Linear Strayfield Immune mode (−200), with different magnetic sensitivity and calibration. | Optimized for linear stroke measurement in high-stray-field environments (e.g., transmission shift actuators), not rotary applications. | Choose −200 only for linear position use cases requiring enhanced stray-field rejection beyond −301 specifications. |
Compared with MLX90372GVS-ACE-301-SP, the −300 variant omits Pin 4's NTC/gateway function but retains identical accuracy and timing; the −200 variant trades rotary flexibility for higher linear-mode stray-field immunity, making it unsuitable for throttle or steering applications.

FAQ
What is the pin configuration of the MLX90372GVS-ACE-301-SP?
The MLX90372GVS-ACE-301-SP uses DMP-4 Pinout-B: Pin 1 = OUT (SENT/PWM), Pin 2 = VSS (ground), Pin 3 = VDD (supply), Pin 4 = Input (NTC or analog/digital gateway). This differs from Pinout-A by relocating OUT to Pin 1 and assigning dedicated Input functionality to Pin 4, enabling on-chip temperature sensing or auxiliary signal routing without external components.
Does the MLX90372GVS-ACE-301-SP support both SENT and PWM output modes?
Yes, the MLX90372GVS-ACE-301-SP supports both SENT and PWM output protocols, programmable via on-chip NVM. In SENT mode, it complies with SAE J2716 APR2016 using 3 µs tick time and delivers secure sensor frames with CRC, error codes, and user-defined values. PWM mode provides pulse-width modulated output with configurable frequency and duty cycle, suitable for legacy ECU interfaces lacking SENT capability.
What safety certifications apply to the MLX90372GVS-ACE-301-SP?
The MLX90372GVS-ACE-301-SP is certified as an ISO26262 ASIL-C Safety Element out of Context (SEooC) and qualified to AEC-Q100 Grade 0 (−40°C to +160°C). These certifications confirm its suitability for integration into ASIL-C automotive safety architectures when combined with appropriate system-level mechanisms, and validate its reliability for under-hood applications including engine control and transmission systems.
How does the MLX90372GVS-ACE-301-SP achieve stray magnetic field immunity?
The MLX90372GVS-ACE-301-SP achieves stray-field immunity through Triaxis® Hall technology that measures all three orthogonal magnetic components (Bx, By, Bz), combined with on-chip DSP algorithms that reject common-mode interference. In Standard/Legacy Mode (−300/−301), it maintains specified accuracy in stray fields up to 1 mT - validated per IEC 61000-4-8 and automotive EMC test plans - enabling robust operation near motors, solenoids, and high-current wiring without external shielding.
What is the meaning of "ACE-301" in the MLX90372GVS-ACE-301-SP part number?
In MLX90372GVS-ACE-301-SP, "ACE" denotes the preferred chip revision (standard for new designs), "3" selects Standard/Legacy Mode (rotary/linear position), "0" specifies SENT 3µs mode, and "1" indicates capacitor configuration #2 for DMP-4 Pinout-B - a layout-optimized variant supporting specific external filtering networks defined in Section 15.3 of the datasheet.
