Product details
Overview
MLX90371GVS-BCC-150-RE from Melexis is a Triaxis® monolithic position processor IC that measures all three magnetic field components (BX, BY, BZ) to deliver absolute rotary position output with 12-bit resolution and ±1.5° angular accuracy in Rotary Stray-Field Immune Mode. It operates from -40°C to +160°C, supports ratiometric analog or PWM output, and integrates on-chip DSP for robust stray-field immunity-used in automotive throttle and steering wheel position sensing.
For engineers reviewing the MLX90371GVS-BCC-150-RE datasheet, pinout, applications, or equivalent options, this page provides verified package mapping (DMP-4), confirmed pin functions (VDD/VSS/OUT), real-world timing specs (462 µs latency), ISO26262 ASIL-B safety compliance, and validated alternatives for pedal, ride height, and float-level sensor designs.
Technical Context
The MLX90371GVS-BCC-150-RE implements Triaxis® Hall sensing with integrated IMC and 12-bit ADC, enabling simultaneous acquisition of BX, BY, and BZ for vector-based angle computation. Its programmable FIR filter (FIR1/FIR11/FIR1111) and exponential moving average filter allow configurable response time from 482 µs to 5.1 ms.
This variant uses Rotary Stray-Field Immune Mode with 100 mT Z-axis field requirement and 25 mT in-plane field tolerance. It features dual-ground architecture (VSS pins 1 & 4), internal regulator with VDEC not present in DMP-4, and push-pull output stage supporting 150–2000 Hz PWM frequency with ±5% tolerance.

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90372GVS-BCC-150-RE | Same DMP-4 package and Rotary Stray-Field Immune Mode, but adds EEPROM-based self-test and enhanced diagnostic coverage per ISO26262 Annex G. | Required where ASIL-C decomposition mandates higher diagnostic coverage (>90%) or periodic on-demand self-test capability. | Select MLX90372GVS-BCC-150-RE only if functional safety architecture requires diagnostic test triggers or extended fault memory logging. |
| TLE5012BE1000XUMA1 | Infineon's GMR-based 14-bit resolver-to-digital converter with SPI interface; no analog/PWM output; requires external MCU for signal conditioning. | Suitable for new designs with available microcontroller resources and need for multi-sensor fusion via digital bus. | Choose TLE5012BE1000XUMA1 when migrating to digital-only architectures and accepting added BOM cost for external processing. |
Compared with MLX90371GVS-BCC-150-RE, the MLX90372 offers higher diagnostic depth at same pinout and form factor, while the TLE5012B shifts system responsibility to the host MCU-making MLX90371GVS-BCC-150-RE optimal for analog/PWM-native ECUs needing minimal layout changes and proven field reliability.

FAQ
What is the operating temperature range for MLX90371GVS-BCC-150-RE?
The MLX90371GVS-BCC-150-RE is qualified for continuous operation from -40°C to +160°C, meeting AEC-Q100 Grade 0 requirements. This range covers under-hood locations such as throttle bodies and transmission housings. The device maintains 12-bit resolution and ±1.5° angular accuracy across the full span, with built-in thermal compensation algorithms implemented in its on-chip DSP firmware.
Does MLX90371GVS-BCC-150-RE support both analog and PWM outputs simultaneously?
No, MLX90371GVS-BCC-150-RE supports either ratiometric analog output or PWM output-not both at once. Output mode is selected during end-user programming via I²C or SENT interface before deployment. The analog output spans 0–100% VDD with 12-bit resolution, while PWM offers 150–2000 Hz frequency and 0.1% duty cycle resolution, both fully configurable per application needs.
How is stray-field immunity achieved in MLX90371GVS-BCC-150-RE?
MLX90371GVS-BCC-150-RE achieves stray-field immunity through hardware-level Triaxis® vector rejection in Rotary Stray-Field Immune Mode (BCC-150). It uses orthogonal magnetic field component subtraction (BX/BY vs. BZ) and proprietary on-die signal processing to suppress interference up to ±100 mT orthogonal to the sensing axis-validated per ISO11452-8 radiated immunity testing without external shielding.
What package type does MLX90371GVS-BCC-150-RE use, and what are its mounting requirements?
MLX90371GVS-BCC-150-RE uses the DMP-4 (Dual Mold Package), a PCB-less 4-lead surface-mount device with straight leads (STD4 2.54 mm pitch per ordering code -150). It requires reflow soldering per Melexis specification 004, with no external decoupling capacitor needed due to integrated 100 nF capacitance. Mounting must ensure mechanical stability and thermal path to heatsink or carrier plate for 160°C operation.
Is MLX90371GVS-BCC-150-RE certified for functional safety applications?
Yes, MLX90371GVS-BCC-150-RE is certified as an ISO26262 ASIL-B Safety Element out of Context (SEooC). Its safety manual (Rev. 004) documents diagnostic coverage, FIT rate (122 failures per billion hours), and safe failure fraction (92.3%). It supports systematic fault detection including broken-wire, overvoltage, and thermal shutdown-enabling integration into ASIL-B or decomposed ASIL-C systems without additional hardware redundancy.
