Technical Context
The MLX90372GVS-ACC-303-RX implements a Triaxis® Hall front end that measures all three orthogonal magnetic field components (Bx, By, Bz), enabling robust absolute angle decoding without mechanical contact. Its on-chip DSP supports programmable piecewise linear (PWL) transfer characteristics-up to 32 points-and configurable SENT frame structure per SAE J2716 APR2016.
This variant uses the ACC chip revision in DMP-4 package with Pinout-B (VSS/VDD/OUT/Input), supporting NTC or analog/digital gateway functions on the Input pin. It operates in legacy mode (-300 option code), delivering 8–12.6 mA supply current across -40°C to +160°C at 4.5–5.5 V supply, with SENT 3 µs tick timing and fast startup (≤12.4 ms safe startup time).

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-303-RX | Uses ACE chip revision instead of ACC; improved startup timing (11.2 ms vs. 12.4 ms) and enhanced diagnostics coverage. | Same DMP-4 Pinout-B, legacy mode, and SENT/PWM capability - drop-in replacement where latest firmware and safety features are required. | Select ACE-303 for new designs; ACC-303 remains production-supported but not recommended for new projects per Melexis documentation. |
| MLX90371GVS-ACC-303-RX | Single-output SENT-only variant (no PWM support); identical DMP-4 Pinout-B and ACC-303 configuration. | Used where PWM is unnecessary and lower cost or reduced test complexity is prioritized - e.g., non-safety-critical float-level or basic rotary sensing. | Choose MLX90371 if PWM output is unused; MLX90372GVS-ACC-303-RX retains full flexibility for dual-protocol validation and future feature enablement. |
Compared with MLX90372GVS-ACE-303-RX, the ACC-303 variant offers identical functionality but with slightly longer safe startup and older silicon revision; versus MLX90371GVS-ACC-303-RX, it adds PWM output capability and broader diagnostic coverage - critical for ASIL-C system partitioning.

What output protocols does the MLX90372GVS-ACC-303-RX support?
The MLX90372GVS-ACC-303-RX supports both SENT (SAE J2716 APR2016 compliant) and PWM output modes, selectable via end-user programming. SENT frames include CRC, diagnostics, and 48-bit ID; PWM offers fixed-frequency duty-cycle modulation. The device defaults to SENT in factory configuration and maintains full protocol compatibility across its operating temperature range (-40°C to +160°C).
Is the MLX90372GVS-ACC-303-RX pin-compatible with other MLX90372 variants in DMP-4 package?
Yes - MLX90372GVS-ACC-303-RX uses DMP-4 Pinout-B (OUT/VSS/VDD/Input), matching all other VS-coded MLX90372 variants with Pinout-B configuration (e.g., ACE-303, ADE-303). Pinout-A variants (e.g., ACC-300) differ in terminal order and are not interchangeable without PCB redesign.
What is the functional safety qualification status of the MLX90372GVS-ACC-303-RX?
The MLX90372GVS-ACC-303-RX is certified as an ISO26262 ASIL-C Safety Element out of Context (SEooC), with built-in mechanisms including dual watchdogs (IWD/AWD), memory ECC, diagnostic cycle timing, and CRC-protected SENT output. It requires proper system-level integration to achieve full ASIL-C compliance in final ECU architecture.
Does the MLX90372GVS-ACC-303-RX require external decoupling capacitors?
No - the DMP-4 package integrates internal decoupling capacitance, eliminating the need for external VDEC capacitors. This simplifies layout, reduces bill-of-materials count, and improves reliability in space-constrained modules such as pedal or throttle sensor housings.
What magnetic configurations does the MLX90372GVS-ACC-303-RX support?
The MLX90372GVS-ACC-303-RX operates in legacy mode (-300 option code), supporting both absolute rotary (0–360°) and linear position sensing using appropriate magnet geometries and flux concentration. It does not support stray-field immune variants (-100/-200/-500 codes), which require different chip revisions and magnetic circuit designs.
