Product details
Overview
MLX90372GVS-ACE-350-RX from Melexis is a Triaxis® monolithic magnetic position processor IC for absolute rotary and linear position sensing. It integrates a 3-axis Hall front end, DSP-based signal conditioning, SENT/PWM output stage, and operates from -40°C to +160°C with AEC-Q100 qualification and ISO 26262 ASIL-C safety certification. Used in throttle, pedal, and steering wheel position sensing where stray-field immunity and robust non-contact measurement are required.
For engineers reviewing the MLX90372GVS-ACE-350-RX datasheet, pinout, applications, or equivalent options, this page delivers verified package mapping (DMP-4 Pinout-B), SENT/PWM timing specs, stray-field immune angular/linear mode configuration, and real-world automotive sensor design context - all confirmed from Melexis Revision 8 datasheet (Mar 2019).
Technical Context
The MLX90372GVS-ACE-350-RX implements Triaxis® technology to measure Bx, By, and Bz magnetic field components simultaneously, enabling absolute angle decoding up to 360° or linear displacement without mechanical wear. Its on-chip DSP supports programmable piecewise linear (PWL) transfer characteristics with up to 32 points and configurable filtering for noise suppression in harsh EMI environments.
This variant uses DMP-4 package with Pinout-B (VSS–VDD–OUT–Input), where the Input pin serves as NTC or analog/digital gateway interface. It operates in Standard/Legacy Mode (-350 option code), supporting both SENT (SAE J2716 APR2016) and PWM output with SENT frame tick time of 3 µs and built-in decoupling capacitors per section 15.3.
Key Specifications

IC Role / Device Role / Timing Role: Absolute linear position sensor using calibrated magnetic field gradient, outputting PWM or SENT with user-defined scaling. Use Value: Replaces LVDTs and potentiometers with solid-state reliability; DMP-4 package allows direct mounting on shock absorber housings with no PCB required. |
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-RX | Same DMP-4 Pinout-B package and -350 functionality, but factory-configured for Standard/Legacy Mode without high-field variant tuning. | Identical use in throttle/pedal sensing; differs only in default magnetic sensitivity calibration. | Select ACE-300 if legacy magnetic circuit design is unchanged; ACE-350 adds minor field-range optimization for new layouts. |
| MLX90371GVS-ABD-100-RE | Predecessor Triaxis® IC with fixed 16-point PWL, no SENT support (PWM-only), and no ASIL-C certification. | Limited to non-safety-critical linear/rotary sensing; lacks diagnostic messaging and secure sensor format. | Use only for cost-sensitive legacy designs where SENT, safety certification, or advanced diagnostics are unnecessary. |
Compared with MLX90372GVS-ACE-300-RX, the -350 variant offers identical pinout and core functionality but ships with updated magnetic calibration for broader field tolerance in new mechanical assemblies; versus MLX90371, it adds SENT, ASIL-C, and 32-point PWL - making it suitable for next-generation ASIL-B/C automotive ECUs requiring traceable diagnostics and flexible transfer curve programming.

What is the meaning of the "-350" option code in MLX90372GVS-ACE-350-RX?
The "-350" option code indicates Standard/Legacy Mode (3) with DMP-4 Pinout-B (5) and STD3 2.00 mm trim & form (0), per Table 2 and Section 18.12 of the datasheet. It configures the MLX90372GVS-ACE-350-RX for angular/linear position sensing with default magnetic sensitivity and SENT 3 µs timing, distinguishing it from stray-field immune variants (-100/-200) or alternate capacitor configurations (-301/-303).
Is MLX90372GVS-ACE-350-RX qualified for automotive applications, and what safety standards does it meet?
Yes, MLX90372GVS-ACE-350-RX is AEC-Q100 qualified (Grade 0) and certified as an ISO 26262 ASIL-C Safety Element out of Context (SEooC). This enables its use in safety-related systems such as electronic throttle control and brake-by-wire without requiring additional hardware redundancy, as documented in datasheet Sections 1 and 14.
Can MLX90372GVS-ACE-350-RX output PWM instead of SENT, and how is it configured?
Yes, MLX90372GVS-ACE-350-RX supports selectable PWM output alongside SENT. Configuration is performed via end-user programmable memory (NVRAM) using Melexis' PTC software tool. The PWM duty cycle is linearly proportional to measured position, with timing parameters including period and resolution fully configurable per datasheet Section 13.1.2 and Table 11.
