For engineers reviewing the MLX90372GVS-ACE-100-RX datasheet, pinout, applications, or equivalent options, this page provides verified pin definitions, real-world automotive use cases, functional alternatives, and supply-chain-ready procurement details for pedal, throttle, and steering position sensing designs.
Technical Context
The MLX90372GVS-ACE-100-RX integrates a Triaxis® Hall front end sensitive to Bx, By, and Bz magnetic field components, enabling true 3D magnetic vector decoding for absolute angle or linear displacement. Its on-chip DSP implements programmable piecewise-linear (PWL) transfer characteristics with up to 32 points and configurable filtering for robust stray-field immunity.
This DMP-4 packaged variant uses Pinout-A (VSS–VDD–OUT–VSS), supports SENT 3µs mode by default, and embeds decoupling capacitors per section 15.3. It is factory-configured for Angular Rotary Strayfield Immune – Low Field Variant (-100 code), delivering enhanced immunity against external magnetic interference without external shielding.

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute magnetic position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90371GVS-ABD-100-RX | Single-die predecessor; lacks ASIL-C certification and SENT v4.0 support; lower accuracy (±0.5°) | Legacy designs requiring cost reduction where ASIL-C is not mandated | Select only for non-safety-critical industrial controls with existing MLX90371 qualification |
| AMS AS5055A-BQFT | 12-bit SPI output only; no SENT/PWM; requires external MCU for diagnostics; ±0.4° accuracy | Space-constrained consumer or industrial encoders where serial interface flexibility outweighs automotive compliance | Choose when SPI integration simplifies host architecture and stray-field immunity is less critical than in automotive use |
Compared with MLX90372GVS-ACE-100-RX, the MLX90371GVS-ABD-100-RX offers lower cost but omits ASIL-C and advanced SENT diagnostics, while the AMS AS5055A-BQFT trades automotive robustness for compact SPI interface - making MLX90372GVS-ACE-100-RX the sole choice for new ASIL-B/C throttle or pedal designs requiring stray-field immunity and SENT compliance.

FAQ
What is the primary magnetic sensing architecture used in the MLX90372GVS-ACE-100-RX?
The MLX90372GVS-ACE-100-RX employs Melexis' proprietary Triaxis® Hall technology, which simultaneously measures all three orthogonal components (Bx, By, Bz) of the applied magnetic flux density. This 3D vector sensing enables precise absolute angular or linear position decoding without mechanical contact, and is fundamental to the device's stray-field immunity in the -100 configuration.
Does the MLX90372GVS-ACE-100-RX support both SENT and PWM outputs simultaneously?
No - the MLX90372GVS-ACE-100-RX supports either SENT or PWM output, selected during programming via its non-volatile memory. The -100 option code configures it for SENT 3µs mode by default, and reprogramming to PWM requires Melexis' PTC software and compatible programmer. Dual-output operation is not supported in hardware.
What does the "-RX" suffix indicate in MLX90372GVS-ACE-100-RX?
The "-RX" suffix denotes tape-and-reel packaging with parts oriented face-down - a handling specification specific to the DMP-4 package. It ensures consistent orientation during automated pick-and-place assembly and is functionally identical to the "-RE" variant except for part orientation on the reel; both share identical electrical, thermal, and reliability specifications.
Is external decoupling required when using the MLX90372GVS-ACE-100-RX in DMP-4 package?
No - the MLX90372GVS-ACE-100-RX in DMP-4 Pinout-A configuration includes built-in decoupling capacitors per section 15.3 of the datasheet. This eliminates the need for an external 100 nF ceramic capacitor, reducing BOM count and PCB footprint while maintaining stable operation across temperature and vibration.
How is stray-field immunity achieved in the MLX90372GVS-ACE-100-RX?
Stray-field immunity in the MLX90372GVS-ACE-100-RX is achieved through a combination of on-die differential sensing topology, adaptive digital filtering, and factory-programmed calibration for the low-field variant (-100). It rejects common-mode external magnetic interference up to ±1 mT without external shielding, as validated per ISO 11452-8 test methods.
