Product details
Overview
MLX90371GVS-BCC-358-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 ratiometric analog or PWM output, and implements stray-field immunity in Standard/Legacy mode for automotive pedal and throttle position sensing.
For engineers reviewing the MLX90371GVS-BCC-358-RE datasheet, pinout, applications, or equivalent options, this device requires attention to its DMP-4 package layout, 4-pin terminal mapping, programmable transfer characteristic (up to 32-segment PWL), ISO26262 ASIL-B safety element out-of-context compliance, and magnetic configuration compatibility with legacy Hall-based systems.
Technical Context
The MLX90371GVS-BCC-358-RE integrates on-chip DSP, ADC, temperature sensor, and regulator to perform real-time 3D magnetic field processing and generate calibrated position data. Its architecture includes finite impulse response (FIR) filtering options (FIR1/FIR11/FIR1111), programmable clamping, and diagnostic modes including broken-wire detection on VDD/VSS lines.
This variant uses Standard/Legacy mode (BCC-358), meaning it maintains backward compatibility with prior-generation MLX9036x sensors while supporting full 12-bit analog/PWM output, 48-bit ID storage, and user-programmable scaling, discontinuity point, and gain parameters via NVRAM.

Applications
| Pedal Position Sensing | Throttle Position Sensing |
|---|---|
Use Scenario: Monitoring accelerator or brake pedal angular displacement in electric/hybrid powertrains with high EMC noise. IC Role / Device Role / Timing Role: Absolute position processor converting magnet rotation into calibrated analog/PWM signal for ECU torque demand calculation. Use Value: 12-bit resolution and ±10-bit thermal accuracy ensure <±0.1%FS linearity over -40°C to +160°C, critical for precise pedal travel mapping. | Use Scenario: Detecting throttle valve angle in gasoline/direct-injection engines where vibration and thermal cycling degrade potentiometer reliability. IC Role / Device Role / Timing Role: Contactless replacement for wear-prone potentiometers, delivering ratiometric output compatible with legacy ECU analog inputs. Use Value: Standard/Legacy mode (BCC-358) ensures drop-in compatibility with existing MLX9036x-based designs without firmware or hardware changes. |
| Ride Height Control | Steering Wheel Angle Sensing |
Use Scenario: Measuring suspension travel in adaptive damping systems using linear magnet motion along shock absorber shaft. IC Role / Device Role / Timing Role: Linear position decoder interpreting magnet displacement as absolute height value for real-time damper adjustment. Use Value: Programmable 32-segment PWL transfer curve compensates for non-uniform magnet field gradients, enabling sub-degree repeatability. | Use Scenario: Tracking steering wheel rotation for EPS assist torque calculation and lane-keeping assist functions. IC Role / Device Role / Timing Role: Rotary position sensor providing 0–360° absolute angle with <462 μs latency for time-critical vehicle dynamics control. Use Value: FIR filter selection (FIR1/FIR11/FIR1111) allows trade-off between step response speed (968–5099 μs) and noise rejection in high-vibration chassis environments. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90371GVS-BCC-300-RE | Same DMP-4 package and Standard/Legacy mode, but uses 100 nF internal decoupling capacitor (BCC-300 vs. BCC-358's 10 nF) | Requires different external decoupling strategy - BCC-300 integrates capacitor, BCC-358 mandates external 100 nF | Select BCC-358 when board-level decoupling is preferred for thermal management or cost optimization |
| MLX90363GDC-ABA-000-RE | Legacy SOIC-8 predecessor with fixed 10-bit resolution, no programmable PWL, and no ASIL-B certification | Lacks on-chip diagnostics, lower resolution, and no functional safety qualification - limited to non-safety-critical subsystems | Choose MLX90363 only for cost-sensitive legacy upgrades where ASIL-B and 12-bit resolution are not required |
Compared with MLX90371GVS-BCC-358-RE, the BCC-300 variant simplifies layout by integrating decoupling capacitance but sacrifices flexibility in thermal design; the MLX90363 offers lower BOM cost but omits safety certification, programmability, and resolution needed for modern ADAS and powertrain systems.
