Product details
Overview
MLX90371GVS-BCC-250-SP from Melexis is a Triaxis® monolithic position processor IC that senses BX, BY, and BZ magnetic field components to deliver absolute linear position output with 12-bit resolution, ±10° thermal accuracy, and stray-field immunity in Linear Stray-Field Immune Mode. It operates from -40°C to +160°C, supports programmable ratiometric analog or PWM output, and is qualified per ISO 26262 ASIL-B as a Safety Element out of Context.
For engineers reviewing the MLX90371GVS-BCC-250-SP datasheet, pinout, applications, or equivalent options, this device enables robust non-contact position sensing in high-EMC automotive subsystems where magnetic interference rejection, functional safety compliance, and DMP-4 package integration are critical selection criteria.
Technical Context
The MLX90371GVS-BCC-250-SP implements on-chip DSP-based signal processing to decode absolute linear displacement from triaxial Hall measurements, using finite impulse response (FIR) filtering with selectable tap configurations (FIR1/FIR11/FIR1111) and exponential moving average options. Its internal architecture includes dual ADC channels, temperature compensation logic, and NVRAM for user-programmable transfer characteristics.
This variant uses the DMP-4 package with integrated decoupling capacitors, operates at 4.5–5.5 V supply, draws 6–10 mA typical current in Linear Stray-Field Immune Mode, and delivers 440–462 μs latency with step response up to 5.1 ms depending on filter configuration - all validated across its full -40°C to +160°C operating range.

FAQ
What is the operating temperature range of the MLX90371GVS-BCC-250-SP?
The MLX90371GVS-BCC-250-SP is qualified for continuous operation from -40°C to +160°C, meeting AEC-Q100 Grade 0 requirements. This range supports placement in high-temperature zones such as engine compartments, transmission housings, and brake modules without derating or external cooling.
Does the MLX90371GVS-BCC-250-SP require external decoupling capacitors?
No, the MLX90371GVS-BCC-250-SP uses the DMP-4 package with an integrated 10 nF capacitor (indicated by "-250" option code), eliminating the need for external VDEC or output filtering components. This reduces bill-of-materials count and PCB area versus SOIC-8 or TSSOP-16 variants.
How does the Linear Stray-Field Immune Mode function in the MLX90371GVS-BCC-250-SP?
The Linear Stray-Field Immune Mode (BCC-250) in the MLX90371GVS-BCC-250-SP applies differential signal processing to reject interfering magnetic fields orthogonal to the primary measurement axis, maintaining linearity and accuracy even when exposed to ±1 mT stray fields from nearby actuators or wiring harnesses.
Can the MLX90371GVS-BCC-250-SP output both analog and PWM signals simultaneously?
No, the MLX90371GVS-BCC-250-SP supports either ratiometric analog or PWM output - selected during programming - but not both concurrently. The output stage is configured at initialization and remains fixed until reprogrammed via the TEST pin interface.
Is the MLX90371GVS-BCC-250-SP certified to ISO 26262 ASIL-B?
Yes, the MLX90371GVS-BCC-250-SP is certified as an ASIL-B Safety Element out of Context per ISO 26262:2018 Part 5, with documented safety mechanisms including memory ECC, clock monitoring, and diagnostic output signaling - enabling its use in safety-related vehicle control systems without additional hardware redundancy.
