Product details
Overview
MLX90372GVS-ACE-101-RE from Melexis is a Triaxis® monolithic magnetic position processor IC for absolute rotary position sensing in stray-field-immune configurations. It integrates a 3-axis Hall front end, DSP-based signal conditioning, and SENT 3µs output with Secure Sensor format. Operating from -40°C to +160°C, it delivers ±0.3° angular accuracy in low-field rotary mode and supports PCB-less DMP-4 packaging for automotive pedal and throttle position sensing.
For engineers reviewing the MLX90372GVS-ACE-101-RE datasheet, pinout, applications, or equivalent options, this page provides verified package mapping (DMP-4 Pinout-B), SENT/PWM output configuration, stray-field immunity validation, ISO26262 ASIL-C safety architecture, and AEC-Q100 qualification details critical for automotive sensor design.
Technical Context
The MLX90372GVS-ACE-101-RE implements Triaxis® technology to measure Bx, By, and Bz magnetic components simultaneously, enabling robust absolute angle decoding without mechanical contact. Its on-chip DSP supports programmable piecewise linear (PWL) transfer characteristics with up to 32 points and real-time diagnostics including CRC, watchdog timers (IWD/AWD), and analog/digital diagnostic cycle times (34 µs / 20 ms).
This variant uses DMP-4 Pinout-B configuration (VSS–VDD–OUT–Input), where the Input pin serves as NTC or analog/digital gateway. It operates in Rotary Stray-field Immune Mode (-100 code), optimized for low-field environments with enhanced immunity to external magnetic interference and factory-trimmed for ±0.3° total angular error over temperature.

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-100-RE | Same DMP-4 Pinout-B package and -100 stray-field immune mode, but uses capacitor configuration #1 instead of #2 | Identical angular accuracy and temperature range; differs only in internal RC network tuning for EMI filtering | Select ACE-100-RE if legacy board layout uses configuration #1; ACE-101-RE requires updated capacitor selection per section 15.3 |
| MLX90372GVS-ACE-103-RE | Same DMP-4 Pinout-B and -100 mode, but uses STD2 2.54 trim/form instead of STD1 2.54 | Identical electrical performance; differs in mechanical footprint and mold compound geometry for alternate assembly processes | Choose ACE-103-RE for compatibility with STD2-form pick-and-place tooling; ACE-101-RE matches STD1 2.54 standard reel packaging |
Compared with MLX90372GVS-ACE-100-RE and MLX90372GVS-ACE-103-RE, the MLX90372GVS-ACE-101-RE offers identical core sensing functionality and safety certification but is specifically tuned for capacitor configuration #2 and STD1 2.54 mechanical form-making it optimal for new designs requiring enhanced EMI resilience and standard SMT placement alignment.

FAQ
What is the operating temperature range of the MLX90372GVS-ACE-101-RE?
The MLX90372GVS-ACE-101-RE operates from -40°C to +160°C ambient temperature, fully qualified per AEC-Q100 Grade 0. This range covers under-hood automotive locations including throttle bodies and brake pedals, with no derating required up to maximum junction temperature of +175°C as specified in the absolute maximum ratings table.
Does the MLX90372GVS-ACE-101-RE support both SENT and PWM outputs?
Yes, the MLX90372GVS-ACE-101-RE supports both SENT and PWM output modes via end-user programming. By default, it is configured for SENT 3µs mode (SAE J2716 APR2016) with Secure Sensor format. PWM mode can be enabled through memory programming, delivering pulse-width modulated signals with configurable frequency and duty cycle resolution.
What does the "-101" option code signify in MLX90372GVS-ACE-101-RE?
The "-101" option code identifies three attributes: (1) "1" = Angular Rotary Stray-field Immune – Low Field Variant, (2) "0" = SENT 3µs mode with capacitor configuration #2, and (3) "1" = STD1 2.54 trim & form for DMP-4 packaging. This distinguishes it from ACE-100 (capacitor #1) and ACE-103 (STD2 2.54 form).
Is the MLX90372GVS-ACE-101-RE pin-compatible with earlier Triaxis® generations?
No - MLX90372GVS-ACE-101-RE uses DMP-4 Pinout-B (OUT–VSS–VDD–Input), which differs from Pinout-A (VSS–VDD–OUT–VSS) used in legacy Triaxis® devices. While both are 4-pin DMP-4 packages, the pin order and function assignment require PCB layout revision; direct replacement is not supported without hardware modification.
How is stray-field immunity achieved in the MLX90372GVS-ACE-101-RE?
The MLX90372GVS-ACE-101-RE achieves stray-field immunity through its Triaxis® architecture combined with factory-programmed low-field rotary mode (-100 code). This mode applies differential signal processing across Bx, By, and Bz channels and uses advanced on-chip filtering to reject common-mode magnetic interference exceeding ±10 mT, validated per section 8.1 of the datasheet.
