Product details
Overview
MLX90371GVS-BCC-350-SP from Melexis is a Triaxis® monolithic position processor IC that senses all three magnetic field components (BX, BY, BZ) to deliver absolute rotary or linear position output with 12-bit resolution, ±10° angular accuracy over -40°C to +160°C, and programmable ratiometric analog or PWM output for automotive throttle and pedal sensing.
For engineers reviewing the MLX90371GVS-BCC-350-SP datasheet, pinout, applications, or equivalent options, this device supports ISO26262 ASIL-B functional safety compliance, stray-field immune operation in Standard/Legacy mode, and DMP-4 package integration for compact PCB-less mounting in space-constrained automotive sensor assemblies.
Technical Context
The MLX90371GVS-BCC-350-SP implements on-chip DSP-based signal processing of triaxial Hall sensor data to compute absolute angle or displacement without external microcontroller intervention. Its architecture includes a 12-bit ADC, FIR filtering (configurable up to 4-stage), temperature compensation, and NVRAM-programmable transfer characteristics including 4/8-point LNR or 16/32-segment PWL mapping.
This variant uses the DMP-4 package with dual mold construction and built-in decoupling capacitance, operates from 4.5–5.5 V supply, draws 6–10 mA typical current in Standard/Legacy mode, and delivers latency of 440–462 µs with step response under 2.6 ms depending on filter configuration.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5–5.5 V - compatible with standard automotive 5 V rail; reverse polarity protection to -14 V. |
| Operating Temperature | -40°C to +160°C - qualified for under-hood automotive environments including engine bay and transmission mounts. |
| Output Resolution | 12-bit - enables 0.0879° angular resolution over 360° full scale for high-precision position feedback. |
| Angular Accuracy | ±10° (thermal, magnetic, and linearity combined) - specified for Standard/Legacy mode per datasheet Section 9.1.5. |
| Latency Time | 440–462 µs - deterministic delay between magnetic change and output update, critical for real-time closed-loop control. |
| PWM Frequency Range | 150–2000 Hz - configurable for ECU sampling synchronization; ±5% tolerance over temperature and aging. |
| Stray-Field Immunity | Standard/Legacy mode (BCC-350) - backward-compatible operation without active stray-field cancellation circuitry. |
Pinout & Package
DMP-4 package: 4-pin, dual-mold, PCB-less surface-mount module with integrated decoupling capacitors; dimensions 3.1 × 2.6 × 0.9 mm (L × W × H); leads pre-formed per STD4 2.54 mm pitch (BCC-350 suffix).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VSS | Ground reference for analog and digital sections; must be connected to system ground plane for EMC stability. |
| 2 | VDD | Main power supply input; accepts 4.5–5.5 V with internal regulator and reverse-voltage protection. |
| 3 | OUT | Programmable output terminal supporting ratiometric analog voltage (0–100% VDD) or PWM (150–2000 Hz). |
| 4 | VSS | Dedicated ground return path; dual VSS pins reduce impedance and improve noise immunity in high-EMI environments. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90371GVS-BCC-300-SP | Same DMP-4 package and Standard/Legacy mode, but BCC-300 uses straight leads (STD0) instead of STD4 2.54 mm pitch. | Requires different mechanical mounting fixture; not drop-in compatible due to lead form difference. | Select BCC-300 only if existing tooling supports straight-lead insertion or wave soldering. |
| MLX90372GVS-BCC-350-SP | Successor IC with enhanced ASIL-B diagnostics, improved thermal accuracy (±5°), and extended magnetic range; pinout and firmware interface identical. | Enables higher functional safety integrity without hardware redesign; requires updated calibration and diagnostic software. | Choose MLX90372GVS-BCC-350-SP for new designs targeting ASIL-B compliance with tighter accuracy budgets. |
Compared with MLX90371GVS-BCC-350-SP, the BCC-300 variant offers identical electrical performance but incompatible mechanical mounting, while the MLX90372GVS-BCC-350-SP provides measurable accuracy and diagnostic improvements within the same DMP-4 STD4 footprint-making it the preferred upgrade path for next-generation automotive sensors.

FAQ
What is the operating temperature range of the MLX90371GVS-BCC-350-SP?
The MLX90371GVS-BCC-350-SP is qualified for continuous operation from -40°C to +160°C, meeting AEC-Q100 Grade 0 requirements for under-hood automotive applications. This range covers engine compartment, transmission, and brake system environments where thermal stability is critical. The device maintains specified accuracy and timing performance across this full range without derating.
Does the MLX90371GVS-BCC-350-SP support both analog and PWM output modes?
Yes, the MLX90371GVS-BCC-350-SP supports both ratiometric analog voltage output (0–100% VDD) and programmable PWM output (150–2000 Hz). Output mode selection is configured via on-chip NVRAM programming using Melexis' PTM interface; no external components are required to switch between modes after initial setup.
What package type does the MLX90371GVS-BCC-350-SP use, and how is it mounted?
The MLX90371GVS-BCC-350-SP uses the DMP-4 (Dual Mold Package) with four terminals and pre-formed STD4 2.54 mm pitch leads. It is a PCB-less module designed for direct soldering onto metal housings, flex circuits, or custom substrates-eliminating traditional PCB routing and reducing system-level EMI susceptibility.
Is the MLX90371GVS-BCC-350-SP certified for automotive functional safety standards?
Yes, the MLX90371GVS-BCC-350-SP is designed to support ISO26262 ASIL-B as a Safety Element out of Context (SEooC). It includes integrated diagnostics such as broken-wire detection, memory ECC, watchdog timers, and configurable output clamping-all documented in the official Melexis safety manual for MLX90371.
How does the BCC-350 option code differ from other MLX90371 variants like BCC-100 or BCC-200?
The BCC-350 option code specifies Standard/Legacy mode operation in the DMP-4 package with STD4 2.54 mm lead form. Unlike BCC-100 (Rotary Stray-Field Immune) or BCC-200 (Linear Stray-Field Immune), BCC-350 disables active stray-field compensation-ensuring backward compatibility with legacy calibration routines and magnetic assemblies used in prior-generation systems.
