Product details
Overview
MLX90372GVS-ACC-301-SP 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 built-in capacitors in DMP-4 package, operates from -40°C to +160°C, supports programmable piecewise linear transfer characteristics (up to 32 points), and meets ISO 26262 ASIL-C as a safety element out of context. It is used in automotive throttle and pedal position sensing.
For engineers reviewing the MLX90372GVS-ACC-301-SP datasheet, pinout, applications, or equivalent options, key selection criteria include DMP-4 PCB-less packaging, SENT 3µs timing compliance per SAE J2716 APR2016, stray-field immune legacy mode (-301 option), and integrated decoupling for simplified layout.
Technical Context
The MLX90372GVS-ACC-301-SP implements a Triaxis® front end sensitive to Bx, By, and Bz magnetic field components, enabling robust absolute angle decoding without mechanical contact. Its on-chip DSP performs real-time signal conditioning, filtering, and piecewise linear interpolation using up to 32 user-programmable breakpoints.
It operates in continuous asynchronous acquisition mode by default (TangleMeas = 588 µs typ), outputs SENT frames with Secure Sensor format including error codes and user-defined values, and supports fail-safe state entry within 11.9 ms after digital fault detection. The DMP-4 package uses Pinout-B configuration with dedicated Input pin for NTC or analog/digital gateway functions.

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-301-RE | ACE revision replaces ACC; includes enhanced memory ECC, tighter timing tolerances, and updated safety mechanism implementation | Same DMP-4 Pinout-B, -301 legacy mode, and SENT 3 µs output; intended for new designs per Melexis guidance | Select ACE-301 for production releases requiring full lifecycle support and latest safety certification documentation |
| MLX90371GVS-ACC-301-SP | Single-die variant with identical DMP-4 Pinout-B and -301 option; lacks dual-die redundancy and isolation features of MLX90372 | Matches form, fit, and function for non-safety-critical linear/rotary sensing where ASIL-C is not mandated | Choose MLX90371GVS-ACC-301-SP only when functional safety certification is unnecessary and cost optimization is primary |
Compared with MLX90372GVS-ACC-301-SP, the ACE-301 alternative offers improved long-term reliability and updated safety documentation but requires revalidation of programming files; the MLX90371GVS-ACC-301-SP provides identical mechanical integration and basic functionality at lower cost but omits ASIL-C mechanisms and dual-die fault tolerance.

FAQ
What is the package type and pin configuration of MLX90372GVS-ACC-301-SP?
The MLX90372GVS-ACC-301-SP uses the DMP-4 PCB-less dual-mold package with Pinout-B configuration (VDD, VSS, OUT, Input). It integrates decoupling capacitors and supports NTC or gateway functions on the Input pin. This matches STD1 2.54 trim/form per datasheet section 18.10 and ordering code definition.
Does MLX90372GVS-ACC-301-SP support both SENT and PWM output modes?
Yes, MLX90372GVS-ACC-301-SP supports selectable SENT or PWM output. By default it is configured for SENT 3 µs mode per option code -301. PWM mode can be enabled via end-user programming (section 13.1), with timing defined in Table 11 and Figure 4 of the datasheet. Output drive strength differs between modes.
What does the "ACC-301" option code signify for MLX90372GVS-ACC-301-SP?
The "ACC-301" option code indicates: ACC = legacy chip revision (not recommended for new designs), 3 = legacy/angular rotary/linear position mode, and 01 = SENT 3 µs mode with capacitor configuration #2 for DMP-4 Pinout-B. This defines magnetic configuration, output protocol, and internal capacitor setup per Table 2 and section 15.3.
Is MLX90372GVS-ACC-301-SP certified for automotive functional safety standards?
Yes, MLX90372GVS-ACC-301-SP is qualified to ISO 26262 ASIL-C as a Safety Element out of Context (SEooC) and AEC-Q100 Grade 0. It includes hardware safety mechanisms such as dual watchdogs (IWD/AWD), memory ECC, and diagnostic cycle timing validation, documented in sections 14.1–14.2 of the datasheet.
Can MLX90372GVS-ACC-301-SP operate directly from a 12 V automotive battery?
No, MLX90372GVS-ACC-301-SP requires a regulated 4.5–5.5 V supply. While the datasheet lists battery usage (6–18 V) for other variants, the ACC-301 configuration is specified for regulated mode only (Table 10). An external voltage regulator is mandatory to avoid damage and ensure SENT timing compliance.
