Product details
Overview
MLX90371GVS-BCC-158-SP 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 ±1.5° angular accuracy in Rotary Stray-Field Immune Mode. It operates from -40°C to +160°C, supports ratiometric analog or PWM output, and integrates on-chip DSP, NVRAM, and ISO26262 ASIL-B safety compliance for automotive pedal and throttle sensing.
For engineers reviewing the MLX90371GVS-BCC-158-SP datasheet, pinout, applications, or equivalent options, this device requires attention to its DMP-4 package layout, stray-field immune calibration mode, programmable transfer characteristic, and dual-ground pin configuration for EMC robustness in high-vibration environments.
Technical Context
The MLX90371GVS-BCC-158-SP implements Triaxis® Hall sensing with integrated IMC and 12-bit ADC, feeding a dedicated DSP core that executes real-time angle computation using calibrated multi-point linearization (up to 32-segment PWL). Its architecture includes dual ground paths (VSS pins 1 and 4), on-chip voltage regulator with VDEC decoupling, and reverse-polarity/overvoltage protection circuitry.
It operates in Rotary Stray-Field Immune Mode (BCC-158 variant), enabling accurate angular measurement under external magnetic interference up to ±1 mT. Output is configurable as ratiometric analog (0–100% VDD) or PWM (150–2000 Hz), with latency of 462 μs and step response under 2.6 ms depending on FIR filter selection.

FAQ
What is the operating temperature range of the MLX90371GVS-BCC-158-SP?
The MLX90371GVS-BCC-158-SP is qualified for continuous operation from -40°C to +160°C ambient temperature, meeting AEC-Q100 Grade 0 requirements. This rating applies specifically to the DMP-4 package variant and is validated across all electrical parameters including angular accuracy, latency, and output drive strength. The MLX90371GVS-BCC-158-SP maintains full functionality without derating within this range, making it suitable for under-hood and transmission-mounted applications.
Does the MLX90371GVS-BCC-158-SP require external decoupling capacitors?
No, the MLX90371GVS-BCC-158-SP does not require external decoupling capacitors. Its DMP-4 package integrates a 100 nF ceramic capacitor internally connected to the VDEC pin (pin 2), as confirmed by the BCC-158 option code definition in the ordering information table. This eliminates board space and improves reliability in high-vibration environments where discrete capacitors may fatigue.
How is stray-field immunity implemented in the MLX90371GVS-BCC-158-SP?
The MLX90371GVS-BCC-158-SP achieves stray-field immunity through its Rotary Stray-Field Immune Mode (BCC-158 configuration), which uses differential Triaxis® sensing and proprietary on-chip DSP algorithms to reject orthogonal magnetic interference up to ±1 mT. This mode is factory-programmed and validated per ISO11452-8 test methods, ensuring angular accuracy remains within ±1.5° even when exposed to fields from adjacent actuators or wiring harnesses.
Can the MLX90371GVS-BCC-158-SP output both analog and PWM simultaneously?
No, the MLX90371GVS-BCC-158-SP supports either ratiometric analog or PWM output-not both simultaneously. The output mode is selected during programming via the USEROPTION_OUTMODE parameter and locked in NVRAM. Once configured, the MLX90371GVS-BCC-158-SP delivers only the chosen signal type on the OUT pin, with corresponding timing and drive specifications applying exclusively to that mode.
What safety certification does the MLX90371GVS-BCC-158-SP hold?
The MLX90371GVS-BCC-158-SP is certified as an ISO26262 ASIL-B Safety Element out of Context (SEooC), with documented safety mechanisms including memory ECC, intelligent watchdog (IWD), diagnostic cycle monitoring, and hardware-based fault detection. This certification covers the MLX90371GVS-BCC-158-SP silicon, firmware, and package-enabling direct integration into ASIL-B automotive systems without requiring additional hardware redundancy.
