Product details
Overview
MLX90371GVS-BCC-303-SP from Melexis is a Triaxis® monolithic position processor IC that senses BX, BY, and BZ magnetic field components to deliver absolute rotary or linear position output with 12-bit resolution, ±10° angular accuracy over -40°C to +160°C, and programmable ratiometric analog or PWM output. It operates from 4.5–5.5 V, draws 6–10 mA, and supports ISO26262 ASIL-B functional safety in Standard/Legacy mode.
For engineers reviewing the MLX90371GVS-BCC-303-SP datasheet, pinout, applications, or equivalent options, this page delivers verified specifications, DMP-4 package terminal mapping, real-world use cases in automotive pedal/throttle sensing, and two validated alternative parts for legacy-mode position sensing designs.
Technical Context
The MLX90371GVS-BCC-303-SP implements a Triaxis® Hall sensor front-end with integrated ADC, DSP, and NVRAM to compute absolute angle or displacement from 3-axis magnetic flux density. Its on-chip signal processing includes configurable FIR filtering (FIR1/FIR11/FIR1111), programmable clamping, and diagnostic monitoring for broken-wire detection.
This variant uses Standard/Legacy Mode firmware (BCC-3xx), supports 4/8-point linearization or 16/32-segment piecewise-linear transfer functions, and delivers 440–462 µs latency with 482 µs refresh rate at 18 MHz main clock. Output is selectable between ratiometric analog (0–100% VDD) or PWM (150–2000 Hz).
Key Specifications

Pinout & Package
DMP-4 (Dual Mold Package, PCB-less) with 4 terminals: compact 3.2 × 2.5 mm footprint, no external decoupling required due to integrated VDEC capacitor, designed for direct soldering onto flex or rigid PCBs with STD2 2.54 mm lead pitch (BCC-303).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VSS | Ground reference for analog and digital domains; must be connected to system ground for EMC compliance. |

The MLX90371GVS-BCC-303-SP is qualified for continuous operation from -40°C to +160°C ambient temperature, meeting AEC-Q100 Grade 0 requirements. This range supports under-hood automotive placements such as throttle bodies and brake pedals. The device maintains specified accuracy and latency across the full range, with thermal drift compensated by on-chip temperature sensing and DSP algorithms. MLX90371GVS-BCC-303-SP does not require external thermal derating or heatsinking in compliant layouts.
Does the MLX90371GVS-BCC-303-SP support both analog and PWM outputs?
Yes, the MLX90371GVS-BCC-303-SP supports either ratiometric analog output (0–100% VDD) or PWM output (150–2000 Hz) via end-user programming. The output mode is selected during configuration using Melexis' PTC software and stored in NVRAM. Analog mode features 12-bit resolution and 200 V/ms slew rate with no load; PWM mode offers ±5% frequency tolerance and push-pull drive capability. MLX90371GVS-BCC-303-SP retains its selected mode after power cycle without reprogramming.
What package type is used by the MLX90371GVS-BCC-303-SP?
The MLX90371GVS-BCC-303-SP uses the DMP-4 (Dual Mold Package) with four terminals and STD2 2.54 mm lead pitch. This PCB-less package integrates decoupling capacitance internally, eliminating external VDEC capacitors. Its 3.2 × 2.5 mm footprint enables direct mounting on flex circuits or compact rigid boards. MLX90371GVS-BCC-303-SP is not available in SOIC-8 or TSSOP-16 variants-the "VS" in the part number explicitly denotes DMP-4.
Is the MLX90371GVS-BCC-303-SP certified for functional safety applications?
Yes, the MLX90371GVS-BCC-303-SP is certified as an ISO26262 ASIL-B Safety Element out of Context (SEooC) in Standard/Legacy Mode (BCC-303). This includes documented safety mechanisms such as watchdog timers, memory ECC, diagnostic coverage for sensor front-end and output stage, and fault reporting via output clamping. MLX90371GVS-BCC-303-SP requires integration into a larger ASIL-B system but provides all necessary safety evidence for qualification.
How is the magnetic transfer function programmed on the MLX90371GVS-BCC-303-SP?
The MLX90371GVS-BCC-303-SP supports user-programmable transfer characteristics via Melexis' PTC programming tool and a compatible interface (e.g., PTCLink adapter). Users can configure 4- or 8-point linearization tables or 16-/32-segment piecewise-linear curves to match mechanical travel profiles. Calibration data is written to on-chip NVRAM and persists across power cycles. MLX90371GVS-BCC-303-SP also allows setting discontinuity points, clockwise/counter-clockwise direction, and clamping thresholds-all stored permanently without external memory.
