Product details
Overview
MLX90371GVS-BCC-203-RE 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 and ±10-bit thermal accuracy. It operates from -40°C to +160°C, supports programmable analog (ratiometric) or PWM output, and implements stray-field immune linear mode per BCC-203 configuration for automotive pedal and throttle sensing.
For engineers reviewing the MLX90371GVS-BCC-203-RE datasheet, pinout, applications, or equivalent options, this device delivers ASIL-B safety compliance, on-chip DSP-based signal processing, and DMP-4 package integration for direct PCB mounting in space-constrained automotive sensor modules.
Technical Context
The MLX90371GVS-BCC-203-RE implements a Triaxis® Hall sensor front-end with integrated IMC, 12-bit ADC, and digital signal processor executing piecewise-linear (16- or 32-segment) transfer function interpolation. Its BCC-203 option configures it for Linear Stray-Field Immune Mode, enabling robust operation under external magnetic interference up to ±1 mT while maintaining <±1.5° angular error over temperature.
It features dual ground pins (VSS), single supply (VDD), and a push-pull output stage supporting either ratiometric analog voltage (0–100% VDD) or 150–2000 Hz PWM with ±5% frequency tolerance. Internal diagnostics include broken-wire detection, intelligent watchdog, and configurable clamping levels aligned to ISO26262 ASIL-B requirements.

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-203-RE | Same DMP-4 package and BCC-203 linear mode, but adds 48-bit unique ID and enhanced diagnostic logging | Required where end-of-line traceability or extended fault history is mandated by OEM safety audits | Select MLX90372GVS-BCC-203-RE only if 48-bit ID or extended diagnostic memory is explicitly required; otherwise MLX90371GVS-BCC-203-RE offers identical core functionality at lower cost |
| TLE5012BE1000XUMA1 | Infineon GMR-based resolver replacement; 16-bit resolution, SPI interface, no analog/PWM output; requires external MCU for signal conditioning | Suitable for designs already using SPI-based sensor networks and needing higher resolution, but not drop-in compatible due to interface and output architecture differences | Choose TLE5012BE1000XUMA1 only when migrating to SPI-based architectures or requiring >12-bit resolution; MLX90371GVS-BCC-203-RE remains optimal for analog/PWM ECU interfaces and minimal BOM count |
Compared with MLX90372GVS-BCC-203-RE, the MLX90371GVS-BCC-203-RE omits 48-bit ID and advanced diagnostics but retains identical position accuracy, latency, and stray-field immunity-making it ideal for cost-sensitive automotive Tier 2 suppliers. Versus TLE5012BE1000XUMA1, it avoids SPI dependency and external signal conditioning, reducing system-level validation effort for analog/PWM ECUs.

FAQ
What is the operating temperature range of the MLX90371GVS-BCC-203-RE?
The MLX90371GVS-BCC-203-RE is qualified for continuous operation from -40°C to +160°C, meeting AEC-Q100 Grade 0 requirements. This range covers under-hood environments such as transmission control units, throttle bodies, and suspension modules where ambient temperatures exceed 125°C. The device maintains specified accuracy and latency performance across this full range without derating.
Does the MLX90371GVS-BCC-203-RE require external decoupling capacitors?
No, the MLX90371GVS-BCC-203-RE does not require external decoupling capacitors. Its DMP-4 package integrates internal decoupling, and the VDEC function is embedded within the die. The datasheet confirms that no external capacitor is needed for stable operation-reducing BOM count and PCB area versus SOIC-8 or TSSOP-16 variants.
How does the BCC-203 option affect the MLX90371GVS-BCC-203-RE's magnetic performance?
The BCC-203 option configures the MLX90371GVS-BCC-203-RE for Linear Stray-Field Immune Mode, which guarantees operation under orthogonal magnetic interference up to ±1 mT while maintaining <±1.5° angular error. This mode uses dedicated internal compensation algorithms and optimized gain settings-distinct from BCC-100 (rotary) or BCC-300 (legacy) configurations-and is validated per section 8.3 of the datasheet.
Can the MLX90371GVS-BCC-203-RE output both analog and PWM signals simultaneously?
No, the MLX90371GVS-BCC-203-RE supports either ratiometric analog voltage output or PWM output-not both simultaneously. The output mode is selected during programming via NVRAM configuration (USEROPTION_OUTMODE). Once set, the device operates exclusively in the chosen mode until reprogrammed using Melexis' PTM or EVK tools.
Is the MLX90371GVS-BCC-203-RE compliant with ISO26262 functional safety standards?
Yes, the MLX90371GVS-BCC-203-RE is certified as an ASIL-B Safety Element out of Context (SEooC) per ISO26262-5:2018. It includes on-chip diagnostics such as memory ECC, watchdog timers, and broken-wire detection, and its safety manual (document MLX90371-SM) defines integration requirements for achieving ASIL-B system compliance-without requiring external safety monitors.
