Product details
Overview
MLX90371GVS-BCC-250-RE from Melexis is a Triaxis® monolithic position processor IC that measures all three orthogonal 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-250 configuration for automotive pedal and throttle sensing.
For engineers reviewing the MLX90371GVS-BCC-250-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 control modules.
Technical Context
The MLX90371GVS-BCC-250-RE uses integrated IMC and Hall elements to capture BX, BY, BZ simultaneously, feeding a dedicated DSP for real-time angle or displacement calculation. Its BCC-250 option configures it for Linear Stray-Field Immune Mode, enabling robust operation under external magnetic interference up to ±1 mT.
It features a 12-bit analog output with 0.5–98% VDD saturation range and a programmable 150–2000 Hz PWM output with ±5% frequency tolerance. Internal diagnostics include broken-wire detection on VDD/VSS and clamped output levels configurable via NVRAM.

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-250-RE | Same DMP-4 package and BCC-250 linear mode, but adds EEPROM-based user-programmable ID and extended diagnostic reporting | Required where traceability or enhanced fault logging is mandated by OEM functional safety requirements | Select when end-user programmability of 48-bit ID and additional diagnostic flags is needed beyond base MLX90371 functionality |
| AMS AS5055A-DSO | SOIC-8 package, 12-bit SPI output only, no analog/PWM dual-mode support, lower stray-field immunity (no BCC-250 equivalent) | Suitable for cost-sensitive non-safety-critical industrial encoders, not certified for ASIL-B automotive use | Choose only for non-automotive applications where SPI interface and lower EMI immunity suffice |
Compared with MLX90371GVS-BCC-250-RE, MLX90372GVS-BCC-250-RE extends programmability while maintaining pinout and timing; AMS AS5055A-DSO offers SPI simplicity but lacks ASIL-B qualification, analog output, and stray-field resilience required for automotive pedal/throttle systems.

FAQ
What is the operating temperature range of the MLX90371GVS-BCC-250-RE?
The MLX90371GVS-BCC-250-RE is qualified for continuous operation from -40°C to +160°C, meeting AEC-Q100 Grade 0 requirements for under-hood automotive placement. This range is validated across all electrical parameters including supply current, output accuracy, and latency time, ensuring reliable performance in engine bay and transmission control modules.
Does the MLX90371GVS-BCC-250-RE support both analog and PWM outputs simultaneously?
No, the MLX90371GVS-BCC-250-RE supports either ratiometric analog voltage or PWM output-not both concurrently. The output mode is selected during programming via its NVRAM configuration; switching requires reprogramming the device. The OUT pin delivers one defined signal type per configuration, with full 12-bit resolution preserved in either mode.
How does the BCC-250 option affect the MLX90371GVS-BCC-250-RE's magnetic performance?
The BCC-250 option configures the MLX90371GVS-BCC-250-RE for Linear Stray-Field Immune Mode, which modifies internal gain and filtering to maintain ±0.1% full-scale accuracy under external magnetic fields up to ±1 T-critical for placement near EV inverters or starter motors. This mode is factory-trimmed and cannot be changed post-production.
Is the MLX90371GVS-BCC-250-RE pin-compatible with other MLX90371 variants in DMP-4 package?
Yes, all MLX90371 variants in DMP-4 package-including MLX90371GVS-BCC-100-RE, MLX90371GVS-BCC-250-RE, and MLX90371GVS-BCC-300-RE-share identical 4-pin DMP-4 pinout (VSS-VDD-OUT-VSS), same mechanical footprint, and identical solder pad layout, enabling hardware reuse across rotary, linear, and legacy configurations.
What safety certification does the MLX90371GVS-BCC-250-RE hold?
The MLX90371GVS-BCC-250-RE is certified as an ASIL-B Safety Element out of Context per ISO 26262, with documented safety mechanisms covering memory ECC, clock monitoring, signal path diagnostics, and watchdog timers. Its safety manual (Rev. 004) provides FMEDA data, diagnostic coverage metrics, and integration guidance for system-level ASIL decomposition.
