Product details
Overview
MLX90372GVS-ACE-350-RE from Melexis is a monolithic Triaxis® Hall-based magnetic position processor IC for absolute rotary and linear position sensing. It delivers SENT output compliant with SAE J2716 APR2016, operates from -40°C to +160°C, features ISO26262 ASIL-C safety certification as a Safety Element out of Context, and uses the DMP-4 PCB-less package with Pinout-B configuration (VSS/VDD/OUT/Input). It enables non-contacting throttle, pedal, and steering wheel position sensing in automotive powertrain and chassis systems.
For engineers reviewing the MLX90372GVS-ACE-350-RE datasheet, pinout, applications, or equivalent options, this page provides verified functional context, DMP-4 Pinout-B terminal mapping, SENT/PWM dual-output timing behavior, stray-field-immune angular/linear measurement capability, and AEC-Q100 qualified operation up to 160°C ambient.
Technical Context
The MLX90372GVS-ACE-350-RE integrates a Triaxis® Hall front end sensitive to Bx, By, and Bz magnetic components, an analog-to-digital signal conditioner, and a DSP for real-time angle decoding. Its DMP-4 package with Pinout-B includes dedicated Input pin for NTC or analog/digital gateway functions, enabling temperature compensation or system-level diagnostics integration without external circuitry.
This variant supports SENT 3µs mode with standard capacitor configuration (Option Code ACE-350), operates across 4.5–5.5 V regulated supply or 6–18 V battery input, and implements programmable piecewise linear (PWL) transfer characteristics (up to 32 points) and configurable diagnostic cycle times for ASIL-C compliance in safety-critical applications.

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-RE | Same DMP-4 package and Pinout-B, but configured for legacy angular/linear mode without stray-field immunity optimization. | Lower cost for non-critical applications where external magnetic noise is absent; lacks enhanced stray-field rejection. | Select when operating in magnetically quiet environments and full ASIL-C decomposition is not required. |
| MLX90371GVS-ABD-100-RE | Predecessor Triaxis® device with fixed 16-point PWL, no SENT protocol support, and only PWM output. | Not suitable for new ASIL-C designs; lacks SENT error coding, 48-bit ID, and programmable diagnostics. | Use only for legacy redesigns where SENT is unnecessary and cost sensitivity outweighs functional safety requirements. |
Compared with MLX90372GVS-ACE-350-RE, the -300 variant offers identical hardware but reduced magnetic immunity tuning, while the MLX90371 lacks SENT, ASIL-C qualification, and advanced programmability - making the -350 the only option supporting full SAE J2716-compliant, safety-certified position feedback in compact DMP-4 form.

FAQ
What output protocols does the MLX90372GVS-ACE-350-RE support?
The MLX90372GVS-ACE-350-RE supports both SENT per SAE J2716 APR2016 and PWM output modes, selectable via end-user programming. SENT operation includes Secure Sensor format with CRC, error flags, and 48-bit ID; PWM supports configurable duty cycle and frequency. The MLX90372GVS-ACE-350-RE defaults to SENT 3µs mode per its ACE-350 option code.
What is the significance of the "ACE-350" option code in MLX90372GVS-ACE-350-RE?
The ACE-350 option code specifies three attributes: ACE = standard preferred chip revision, 3 = legacy/angular-linear position mode (not stray-field immune), and 50 = DMP-4 Pinout-B with STD3 2.00 mm trim/form and SENT 3µs mode. This distinguishes MLX90372GVS-ACE-350-RE from ACE-100 (stray-field immune) or ACE-300 (same function but STD1 1.27 mm form).
How does the MLX90372GVS-ACE-350-RE achieve ISO26262 ASIL-C compliance?
The MLX90372GVS-ACE-350-RE is certified as a Safety Element out of Context (SEooC) per ISO26262, meaning its internal safety mechanisms-including dual watchdogs (IWD/AWD), memory ECC, diagnostic cycle timers, and SENT error coding-are validated to support ASIL-C system integration. The MLX90372GVS-ACE-350-RE requires no additional hardware redundancy when used within a properly architected safety manager.
Can the MLX90372GVS-ACE-350-RE operate directly from a 12 V battery supply?
Yes, the MLX90372GVS-ACE-350-RE supports battery-supplied operation from 6 V to 18 V, with internal regulation generating stable 3.3 V analog and 1.85 V digital rails. Its PTC overvoltage detection triggers at 21.5–24.5 V, and undervoltage lockout activates below 3.75–4.25 V, ensuring robustness during cranking and load-dump events common in 12 V automotive systems.
What is the role of the "Input" pin on the MLX90372GVS-ACE-350-RE DMP-4 Pinout-B package?
The Input pin (Pin 4) on the MLX90372GVS-ACE-350-RE's DMP-4 Pinout-B package serves as an NTC thermistor interface or analog/digital gateway, enabling direct temperature compensation of magnetic measurements or injection of external signals for diagnostics. Unlike Pinout-A, Pinout-B exposes this pin explicitly-making MLX90372GVS-ACE-350-RE suitable for applications requiring integrated thermal correction without added components.
