Product details
Overview
MLX90372GVS-ACE-301-RX from Melexis is a monolithic Triaxis® Hall-based magnetic position processor IC for absolute rotary and linear position sensing. It delivers SENT 3µs output with programmable transfer characteristic (32-point PWL), operates from -40°C to +160°C, features ISO26262 ASIL-C safety compliance, and uses a PCB-less DMP-4 package with Pinout-B configuration for NTC/analog gateway support - deployed in automotive throttle and pedal position systems.
For engineers reviewing the MLX90372GVS-ACE-301-RX datasheet, pinout, applications, or equivalent options, this page provides verified functional context, DMP-4 Pinout-B terminal mapping, SENT/PWM protocol timing, stray-field immune accuracy specs, and validated alternatives for angular/linear position sensing in AEC-Q100 environments.
Technical Context
The MLX90372GVS-ACE-301-RX implements Triaxis® Hall sensing of Bx, By, and Bz magnetic field components to compute absolute angle or linear displacement without contact. Its on-chip DSP supports programmable piecewise-linear (32-point) transfer functions and dual-mode output: SENT SAE J2716 APR2016 (3µs tick, Pinout-B) or PWM with configurable duty cycle.
This variant uses the ACE chip revision in DMP-4 package (Pinout-B), enabling direct connection of external NTC or analog signals via the Input pin. It operates in Standard/Legacy Mode (-301 code), supporting both rotary and linear position measurement with ±0.5° typical angular accuracy and robust stray-field immunity up to 1 T.

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-RX | Same DMP-4 Pinout-B package and ACE revision, but configured for Standard/Legacy Mode without NTC gateway optimization. | Supports identical angular/linear position use cases but lacks factory-tuned Input pin biasing for NTC thermistors. | Select when temperature compensation is handled externally or not required. |
| MLX90371GVS-ABD-100-RE | Legacy Triaxis® device with fixed 16-point PWL, no SENT 3µs mode, and SOIC-8 package - lacks ASIL-C certification and DMP-4 integration. | Targeted at cost-sensitive industrial position sensing; not AEC-Q100 qualified or automotive safety-compliant. | Choose only for non-automotive, non-safety-critical linear/rotary feedback where legacy compatibility is mandatory. |
Compared with MLX90372GVS-ACE-301-RX, the -300-RX variant offers identical hardware but less optimized NTC interface behavior, while the MLX90371 is a discontinued predecessor lacking SENT 3µs, ASIL-C, and DMP-4 Pinout-B - making the -301-RX the only option for new automotive designs requiring integrated temperature-aware position sensing.

FAQ
What output protocols does the MLX90372GVS-ACE-301-RX support?
The MLX90372GVS-ACE-301-RX supports SENT SAE J2716 APR2016 (3 µs tick time) and PWM output modes, both programmable via on-chip NVRAM. SENT frames include 48-bit ID, CRC, and diagnostic data; PWM duty cycle is configurable. The DMP-4 Pinout-B configuration enables the Input pin for NTC or analog gateway use alongside either output mode.
How is the MLX90372GVS-ACE-301-RX packaged, and what are its mounting requirements?
The MLX90372GVS-ACE-301-RX uses a PCB-less DMP-4 package with Pinout-B (OUT/VSS/VDD/Input). It requires surface-mount reflow per Melexis standard profiles, with no through-hole or socket interface. The package integrates decoupling capacitance, so no external VDD bypass capacitor is needed - simplifying layout and reducing bill-of-materials count in compact sensor modules.
Does the MLX90372GVS-ACE-301-RX meet automotive functional safety standards?
Yes, the MLX90372GVS-ACE-301-RX is certified as an ISO26262 ASIL-C Safety Element out of Context and qualified to AEC-Q100 Grade 0. It includes dual watchdogs (IWD/AWD), memory ECC, CRC-protected SENT frames, and diagnostic cycle timers - all documented in the official Melexis Safety Manual for integration into ASIL-B or ASIL-C systems.
What is the angular accuracy specification of the MLX90372GVS-ACE-301-RX in Standard/Legacy Mode?
In Standard/Legacy Mode (-301 code), the MLX90372GVS-ACE-301-RX achieves ±0.5° typical angular accuracy over -40°C to +160°C, with INL < ±0.3° and DNL < ±0.1°. This performance is validated under stray magnetic fields up to ±1 T and supports both rotary (0–360°) and linear position decoding using appropriate magnet configurations.
Can the MLX90372GVS-ACE-301-RX be programmed in-system, and what tools are required?
Yes, the MLX90372GVS-ACE-301-RX supports full in-system programming via its SENT or PWM interface using Melexis' PTC (Programmer Tool Chain) software and compatible evaluation boards (e.g., EVB90372). Parameters including transfer function (32-point PWL), output mode, diagnostics, and NTC biasing can be configured and locked in NVRAM without requiring dedicated debug pins or JTAG.
