Product details
Overview
MLX90371GVS-BCC-101-RE from Melexis is a Triaxis® monolithic position processor IC that senses all three magnetic field components (BX, BY, BZ) to deliver absolute rotary position output with 12-bit resolution, ±0.5° angular accuracy in Rotary Stray-Field Immune Mode, and programmable ratiometric analog or PWM output. It operates from -40°C to +160°C in the DMP-4 package and is used in automotive throttle and pedal position sensing.
For engineers reviewing the MLX90371GVS-BCC-101-RE datasheet, pinout, applications, or equivalent options, this page provides verified technical context, pin-level design meaning, real-world application cards, and two validated alternative parts for ASIL-B-compliant position sensing designs.
Technical Context
The MLX90371GVS-BCC-101-RE implements Triaxis® Hall technology with on-chip DSP, ADC, and NVRAM to compute absolute angle from 3D magnetic flux vectors. Its architecture includes integrated temperature compensation, FIR filtering, and programmable transfer characteristics (4/8-point LNR or 16/32-segment PWL).
This variant is configured for Rotary Stray-Field Immune Mode – Low-Field Variant (BCC-101), enabling robust operation under stray-field interference with magnetic field requirements of BX/BY ≤ 25 mT and BZ ≥ 100 mT, and supports ISO 26262 ASIL-B Safety Element out of Context compliance.

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-101-RE | Same DMP-4 package and BCC-101 configuration, but adds EEPROM-based user-programmable ID and extended diagnostic logging. | Required where end-user identification or traceability beyond 48-bit ID is mandated (e.g., Tier-1 OEM serialization). | Select MLX90372GVS-BCC-101-RE only if enhanced NVRAM features are needed; otherwise MLX90371GVS-BCC-101-RE offers identical core sensing performance at lower cost. |
| TLV493DW2B6A1HALR | 3D Hall sensor with I²C interface, 12-bit output, but no on-chip DSP, no programmable transfer curve, and no ASIL-B certification. | Suitable for non-safety-critical consumer or industrial position feedback where host MCU handles linearization and diagnostics. | Choose TLV493DW2B6A1HALR only for cost-sensitive, non-automotive applications lacking functional safety requirements; not a drop-in replacement for ASIL-B systems. |
Compared with MLX90371GVS-BCC-101-RE, MLX90372GVS-BCC-101-RE adds traceability features without altering sensing behavior, while TLV493DW2B6A1HALR requires external processing and lacks safety qualification-making MLX90371GVS-BCC-101-RE the optimal choice for production automotive position sensing.

FAQ
What is the operating temperature range of the MLX90371GVS-BCC-101-RE?
The MLX90371GVS-BCC-101-RE is qualified for continuous operation from -40°C to +160°C, matching under-hood automotive environments. This rating is validated per AEC-Q100 Grade 0 and applies to all electrical and magnetic specifications in the datasheet, including angular accuracy and latency time, without derating.
Does the MLX90371GVS-BCC-101-RE require external decoupling capacitors?
No, the MLX90371GVS-BCC-101-RE does not require external decoupling capacitors. Its DMP-4 package integrates an on-die regulator with internal VDEC functionality, and the datasheet explicitly states "built-in capacitors" for DMP-4 wiring diagrams. External capacitance is unnecessary unless specified for custom EMC filtering.
How is the MLX90371GVS-BCC-101-RE configured for Rotary Stray-Field Immune Mode?
The MLX90371GVS-BCC-101-RE is factory-configured for Rotary Stray-Field Immune Mode – Low-Field Variant (BCC-101), as indicated by its option code. This mode is programmed into NVRAM during test and enables rejection of in-plane stray fields ≤25 mT while maintaining ±0.5° angular accuracy using dedicated DSP algorithms and magnetic front-end tuning.
Can the MLX90371GVS-BCC-101-RE output both analog and PWM simultaneously?
No, the MLX90371GVS-BCC-101-RE supports either ratiometric analog or PWM output-not both simultaneously. The output mode is selected during programming via the USEROPTION_OUTMODE parameter and fixed at startup; switching requires reprogramming the device's NVRAM using Melexis' PTM or EVK tools.
Is the MLX90371GVS-BCC-101-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-101-RE, and MLX90371GVS-BCC-103-RE-share identical 4-pin DMP-4 pinout (VSS, VDD, OUT, VSS), mechanical footprint, and soldering profile, enabling hardware reuse across different magnetic configurations.
