Product details
Overview
MLX90371GVS-BCC-201-RE from Melexis is a Triaxis® monolithic position processor IC that senses all three magnetic field components (BX, BY, BZ) to deliver absolute linear position output with 12-bit resolution and ±1.5° thermal accuracy over −40°C to +160°C. It operates from 4.5–5.5 V, draws 6–10 mA, and supports programmable PWM or ratiometric analog output in Linear Stray-Field Immune Mode for automotive pedal and throttle sensing.
For engineers reviewing the MLX90371GVS-BCC-201-RE datasheet, pinout, applications, or equivalent options, this device delivers ISO26262 ASIL-B safety compliance, stray-field immunity, and user-programmable transfer characteristics-critical for high-reliability automotive position feedback systems requiring functional safety and EMC robustness.
Technical Context
The MLX90371GVS-BCC-201-RE implements Triaxis® Hall sensing with on-chip DSP, ADC, and NVRAM to decode absolute linear displacement from magnet motion using integrated IMC structures. Its DMP-4 package embeds decoupling capacitance and enables PCB-less mounting directly onto flex or metal substrates.
This variant is configured for Linear Stray-Field Immune Mode (BCC-201), featuring programmable 4-/8-point LNR or 16-/32-segment PWL transfer curves, selectable analog/PWM output, and active diagnostics including broken-wire detection on VDD/VSS and clamped output levels-all validated per ISO26262 ASIL-B as a Safety Element out of Context.

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-201-RE | Same DMP-4 package and Linear Stray-Field Immune Mode, but adds integrated EEPROM for factory calibration data storage | Required when end-of-line calibration parameters must be stored on-device rather than in host ECU memory | Select MLX90372 if calibration traceability or post-assembly tuning is needed; otherwise MLX90371GVS-BCC-201-RE reduces BOM cost |
| TLV493DW2B6HTSA1 | 3-axis Hall sensor with I²C interface; no on-chip DSP, PWM, or ASIL-B safety features; 12-bit resolution but only ±2.5° thermal accuracy | Suitable for non-safety-critical consumer or industrial linear/rotary sensing where host MCU handles signal processing | Choose TLV493DW2B6HTSA1 only for cost-sensitive designs without functional safety requirements; not drop-in compatible due to interface and safety architecture differences |
Compared with MLX90371GVS-BCC-201-RE, the MLX90372 offers enhanced data retention but higher unit cost, while the TLV493DW2B6HTSA1 lacks integrated safety mechanisms and requires external processing-making MLX90371GVS-BCC-201-RE the optimal choice for ASIL-B automotive linear position sensing with minimal system-level overhead.

FAQ
What is the operating temperature range of the MLX90371GVS-BCC-201-RE?
The MLX90371GVS-BCC-201-RE is qualified for continuous operation from −40°C to +160°C, meeting AEC-Q100 Grade 0 requirements. This range supports placement in demanding locations such as engine compartments, transmission housings, and brake modules where ambient temperatures exceed 125°C. The device maintains specified accuracy and latency performance across the full range without derating.
Does the MLX90371GVS-BCC-201-RE support both analog and PWM outputs?
Yes, the MLX90371GVS-BCC-201-RE supports both ratiometric analog (0–100% VDD) and programmable PWM outputs. Output mode is selected via end-user programming of the NVRAM; PWM frequency is adjustable from 150 Hz to 2 kHz. No hardware change is required-the same MLX90371GVS-BCC-201-RE die supports either interface through configuration.
How does the Linear Stray-Field Immune Mode (BCC-201) differ from Standard Mode?
The Linear Stray-Field Immune Mode (BCC-201) configures the MLX90371GVS-BCC-201-RE's internal signal processing to reject orthogonal magnetic interference up to ±1 T while preserving sensitivity to the target linear motion axis. Standard Mode (BCC-300) offers higher raw sensitivity but reduced immunity-making BCC-201 essential for under-hood applications near motors, solenoids, or alternators.
Is the MLX90371GVS-BCC-201-RE certified to ISO26262?
Yes, the MLX90371GVS-BCC-201-RE is certified as an ASIL-B Safety Element out of Context (SEooC) per ISO26262-5:2018. This includes documented fault detection coverage, memory ECC, watchdog timers, and diagnostic test routines-enabling its use in ASIL-B systems without requiring additional hardware safety mechanisms.
What package type does the MLX90371GVS-BCC-201-RE use, and what are its mounting advantages?
The MLX90371GVS-BCC-201-RE uses the DMP-4 (Dual Mold Package) with STD4 2.54 mm lead pitch and integrated 100 nF decoupling capacitor. It is PCB-less and designed for direct soldering onto flexible circuits or metal carriers-reducing system size, eliminating solder joint reliability concerns from thermal cycling, and simplifying mechanical integration in tight spaces like pedal assemblies.
