Product details
Overview
MLX90371GVS-BCC-203-SP from Melexis is a Triaxis® monolithic position processor IC that senses BX, BY, and BZ magnetic field components to deliver absolute linear position output with 12-bit resolution, ±10° thermal accuracy, and programmable stray-field immune operation in Linear Stray-Field Immune Mode (BCC-203). It operates from -40°C to +160°C in DMP-4 package and is used in automotive pedal, throttle, and ride height sensing.
For engineers reviewing the MLX90371GVS-BCC-203-SP datasheet, pinout, applications, or equivalent options, this page provides verified technical context, real-world timing and accuracy specs, DMP-4 terminal mapping, functional safety compliance (ASIL-B), and validated alternatives for linear position sensing designs requiring robustness against external magnetic interference.
Technical Context
The MLX90371GVS-BCC-203-SP implements Triaxis® Hall technology with on-chip DSP, ADC, and NVRAM to compute absolute linear position from 3-axis magnetic field inputs. Its internal architecture includes a 12-bit analog output stage, 12-bit PWM generator, temperature sensor, and reverse-polarity/overvoltage protection circuitry.
This variant is factory-configured for Linear Stray-Field Immune Mode (BCC-203), enabling accurate position measurement under external magnetic interference up to ±1 mT while maintaining 12-bit resolution and <968 μs step response time with FIR1 filter enabled. It supports programmable transfer characteristics using 4-, 8-, 16-, or 32-segment piecewise-linear calibration.

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute linear position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90372GVS-BCC-203-SP | Same DMP-4 package and BCC-203 configuration, but adds integrated EEPROM for user-programmable parameters | Enables field-updatable transfer curves and diagnostics without external programming hardware | Select when calibration flexibility or post-deployment parameter tuning is required |
| TLV493DW2B6A1HTSA1 | 3D Hall sensor with I²C interface; 12-bit resolution but no built-in DSP or ASIL-B certification | Requires external MCU for position computation and safety monitoring - increases BOM and software overhead | Select for cost-sensitive non-safety-critical industrial linear sensing where I²C integration is preferred |
Compared with MLX90371GVS-BCC-203-SP, the MLX90372 offers enhanced programmability at the cost of slightly higher supply current, while the TLV493DW2B6A1 requires full host-side signal processing and lacks ISO 26262 qualification - making MLX90371GVS-BCC-203-SP optimal for production automotive linear position systems demanding out-of-context safety compliance and minimal system-level complexity.

FAQ
What is the operating temperature range of the MLX90371GVS-BCC-203-SP?
The MLX90371GVS-BCC-203-SP is qualified for continuous operation from -40°C to +160°C, meeting AEC-Q100 Grade 0 requirements. This range supports placement in harsh under-hood locations such as near throttle bodies or suspension modules where ambient temperatures exceed 125°C. The device maintains specified accuracy and timing performance across this full range without derating.
How does the MLX90371GVS-BCC-203-SP achieve stray-field immunity in linear mode?
The MLX90371GVS-BCC-203-SP achieves stray-field immunity through its BCC-203 factory configuration, which activates a dedicated linear magnetic compensation algorithm within the on-chip DSP. This mode uses differential Triaxis® field measurements and internal reference calibration to reject common-mode interference up to ±1 mT while preserving 12-bit position resolution - confirmed in Section 8.3 of the official datasheet.
Can the MLX90371GVS-BCC-203-SP output both analog and PWM signals simultaneously?
No, the MLX90371GVS-BCC-203-SP supports only one output mode at a time - either ratiometric analog or PWM - selected during programming via the Melexis PTM tool. The output stage is shared, and simultaneous dual-output operation is not supported. Switching modes requires reprogramming the device's NVRAM and power cycling.
What package type does the MLX90371GVS-BCC-203-SP use, and why is it suitable for automotive linear sensing?
The MLX90371GVS-BCC-203-SP uses the DMP-4 (Dual Mold Package), a PCB-less, lead-frame-based surface-mount package with four terminals. Its low profile, high thermal conductivity, and direct magnet coupling capability make it ideal for space-constrained linear position assemblies - such as pedal linkages or suspension rods - where mechanical robustness and thermal stability are critical.
Does the MLX90371GVS-BCC-203-SP require external decoupling capacitors?
Yes, the MLX90371GVS-BCC-203-SP requires an external 100 nF ceramic capacitor between VDD and VSS pins, placed as close as possible to the device. This is mandated by the DMP-4 package's lack of integrated decoupling and is specified in Section 15.3 of the datasheet to ensure stable regulator operation and noise immunity in automotive EMI environments.
