Product details
Overview
MLX90372GVS-ACE-108-RX 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, consumes 9.0–12.6 mA, and uses a PCB-less DMP-4 package with Pinout-B (VSS/VDD/OUT/Input). It is used in automotive throttle and steering wheel position sensing where robustness against external magnetic interference is critical.
For engineers reviewing the MLX90372GVS-ACE-108-RX datasheet, pinout, applications, or equivalent options, this page provides verified functional context, validated DMP-4 Pinout-B terminal roles, confirmed stray-field-immune angular mode operation, SENT 3µs timing compliance, and AEC-Q100/ISO26262 ASIL-C safety implementation details.
Technical Context
The MLX90372GVS-ACE-108-RX implements Triaxis® sensing of Bx, By, and Bz magnetic field components to compute absolute angular position without mechanical contact. Its DSP performs real-time signal conditioning, piecewise linear (PWL) transfer function mapping, and SENT frame encoding with CRC and diagnostic fields.
This variant is configured for Angular Rotary Strayfield Immune mode (Option Code -100), uses DMP-4 Pinout-B (Input pin enabled for NTC or analog/digital gateway), and operates in SENT 3µs mode with standard capacitor configuration (STD4 2.54 trim & form). It supports fail-safe state duration of 9.8–34.6 ms after digital single-event faults.

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-100-RE | Same DMP-4 Pinout-B, identical -100 stray-field-immune angular mode, but shipped in standard tape-and-reel (RE) orientation | No face-down mounting requirement; lacks RX-specific handling for automated placement on curved surfaces | Select when board-level assembly does not require face-down orientation or vacuum nozzle compatibility |
| MLX90372GDC-ACE-100-RE | SOIC-8 package instead of DMP-4; same -100 angular mode and SENT functionality but requires PCB mounting and external decoupling | Used where legacy PCB layout exists or where thermal dissipation via copper pour is preferred over molded housing integration | Select when DMP-4's PCB-less integration is unnecessary and SOIC-8's manufacturability or test access is prioritized |
Compared with MLX90372GVS-ACE-108-RX, the RE-packaged ACE-100 offers identical sensing performance but standard tape orientation, while the SOIC-8 ACE-100 retains full functionality at the cost of added PCB area and external components - making the RX variant optimal for space-constrained, high-volume molded sensor assemblies requiring automated face-down placement.

FAQ
What is the package type and pin configuration of MLX90372GVS-ACE-108-RX?
The MLX90372GVS-ACE-108-RX uses the DMP-4 (Dual Mould Package) with Pinout-B configuration: Pin 1 = OUT, Pin 2 = VSS, Pin 3 = VDD, Pin 4 = Input. This enables NTC temperature sensing or analog/digital gateway functionality. The "RX" suffix indicates face-down tape-and-reel packaging for automated placement on curved or recessed surfaces.
Does MLX90372GVS-ACE-108-RX support both SENT and PWM output modes?
Yes, MLX90372GVS-ACE-108-RX supports both SENT (SAE J2716 APR2016 compliant) and PWM output modes. It is factory-configured for SENT 3µs mode, but end-user programming via I²C or dedicated programmer allows switching to PWM with programmable duty cycle and frequency. Output mode selection is stored in non-volatile memory.
What safety certifications apply to MLX90372GVS-ACE-108-RX?
MLX90372GVS-ACE-108-RX is certified to AEC-Q100 Grade 0 and ISO26262 ASIL-C as a Safety Element out of Context (SEooC). It includes dual watchdogs (IWD/AWD), memory ECC, diagnostic cycle timing, and fail-safe state activation - enabling its use in ASIL-B or ASIL-C subsystems when integrated with appropriate system-level mechanisms.
How does the stray-field immunity of MLX90372GVS-ACE-108-RX work in practice?
The MLX90372GVS-ACE-108-RX implements Angular Rotary Strayfield Immune mode (-100 code), using differential Triaxis® sensing and on-chip signal processing to reject common-mode magnetic interference from nearby actuators, motors, or wiring. This allows accurate angular measurement within ±0.5° even when exposed to 10–20 mT external stray fields - validated per ISO11452-8.
Can MLX90372GVS-ACE-108-RX be programmed in-system after soldering?
Yes, MLX90372GVS-ACE-108-RX supports in-system programming via its dedicated programming interface (using VDD, VSS, and Input pins in special mode). End users can configure output protocol, transfer function (up to 32-point PWL), diagnostics, and safety parameters without removing the device from the final assembly - essential for calibration and variant management in high-volume production.
