Product details
Overview
MLX90371GVS-BCC-158-RX 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 and ±10° thermal accuracy over –40°C to +160°C. It operates in Rotary Stray-Field Immune Mode with programmable linear transfer characteristic (up to 32-segment PWL), ratiometric analog or PWM output, and ISO 26262 ASIL-B safety certification - deployed in automotive throttle and steering wheel position sensing.
For engineers reviewing the MLX90371GVS-BCC-158-RX datasheet, pinout, applications, or equivalent options, key selection criteria include stray-field immunity mode configuration, DMP-4 package mechanical constraints, 4-pin terminal layout, 4.5–5.5 V supply operation, and programmable diagnostic behavior for functional safety compliance.
Technical Context
The MLX90371GVS-BCC-158-RX implements a Triaxis® Hall sensor front-end with integrated IMC, on-chip DSP for real-time angle computation, and configurable FIR/exponential moving average filtering. Its architecture supports user-programmable scaling, discontinuity point (zero-degree) definition, and 4/8/17/32-point piecewise-linear transfer functions.
It delivers dual-output capability via selectable ratiometric analog (0–100% VDD) or PWM (150–2000 Hz) modes, with active diagnostics including broken-wire detection on VDD/VSS and clamped output levels. The device integrates reverse-polarity and overvoltage protection, internal regulator with VDEC decoupling, and 48-bit unique ID storage in NVRAM.

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute rotary position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90372GVS-BCC-158-RX | Enhanced ASIL-B compliance with extended diagnostic coverage; identical DMP-4 pinout and BCC-158 configuration | Required where higher diagnostic coverage metrics (DC) are mandated by OEM safety goals | Select MLX90372GVS-BCC-158-RX when upgrading legacy designs to meet ASIL-B DC > 90% targets |
| TLV493DW2B6HTSA1 | 3D Hall sensor with I²C interface only; no analog/PWM output; lower resolution (12-bit but no thermal accuracy spec) | Suitable for low-cost non-safety applications requiring digital bus communication instead of analog/PWM | Choose TLV493DW2B6HTSA1 only for non-automotive or non-ASIL contexts where I²C readout suffices |
Compared with MLX90371GVS-BCC-158-RX, the MLX90372 variant adds diagnostic coverage depth for stricter ASIL-B decomposition, while TLV493DW2B6HTSA1 trades analog/PWM flexibility and safety qualification for I²C simplicity - neither offers drop-in replacement due to interface and certification gaps.

FAQ
What is the operating temperature range of the MLX90371GVS-BCC-158-RX?
The MLX90371GVS-BCC-158-RX is qualified for continuous operation from –40°C to +160°C ambient temperature, meeting AEC-Q100 Grade 0 requirements. This range supports placement in high-heat zones such as engine compartments and transmission housings. The device maintains specified accuracy and latency performance across this full range, with thermal drift compensated in firmware. MLX90371GVS-BCC-158-RX uses on-die temperature sensing and adaptive calibration to sustain 12-bit resolution and ±10° angular accuracy.
Does the MLX90371GVS-BCC-158-RX require external decoupling capacitors?
No, the MLX90371GVS-BCC-158-RX does not require external decoupling capacitors. Its DMP-4 package integrates a 10 nF output capacitor, as confirmed by the '5' digit in the BCC-158 option code (per datasheet Table 1). The internal regulator and VDEC functionality are fully self-contained. MLX90371GVS-BCC-158-RX achieves stable operation with only the four DMP-4 terminals connected - simplifying PCB layout and reducing bill-of-materials cost in space-constrained modules.
How is stray-field immunity implemented in the MLX90371GVS-BCC-158-RX?
The MLX90371GVS-BCC-158-RX implements stray-field immunity through a dedicated algorithmic mode activated by its BCC-158 configuration. This mode processes BX, BY, and BZ components to reject orthogonal magnetic interference while preserving sensitivity to the intended rotary motion axis. It does not rely on shielding alone - instead, it uses differential field vector analysis and adaptive gain control. MLX90371GVS-BCC-158-RX achieves this without hardware modifications, making it suitable for environments near electric motors or high-current cables where competing sensors fail.
Can the MLX90371GVS-BCC-158-RX output both analog and PWM signals simultaneously?
No, the MLX90371GVS-BCC-158-RX supports either ratiometric analog or PWM output - not both simultaneously. Output mode is selected during programming via the USEROPTION_OUTMODE parameter. Once configured, the single OUT pin delivers the chosen signal type. MLX90371GVS-BCC-158-RX provides flexibility for ECU interface compatibility but requires pre-deployment selection based on system architecture - e.g., analog for legacy controllers, PWM for noise-immune digital capture.
What safety documentation accompanies the MLX90371GVS-BCC-158-RX?
The MLX90371GVS-BCC-158-RX ships with ISO 26262 ASIL-B Safety Element out of Context (SEooC) documentation, including safety manual, FMEDA report, and diagnostic coverage analysis. These materials support integration into ASIL-B or ASIL-C systems when combined with appropriate system-level mechanisms. MLX90371GVS-BCC-158-RX is not certified as a standalone ASIL-B system, but its SEooC status enables reuse in multiple vehicle architectures with documented assumptions of use (AoU) and fault reaction strategies.
