Product details
Overview
MLX90371GVS-BCC-353-SP 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 throttle and pedal position sensing.
For engineers reviewing the MLX90371GVS-BCC-353-SP datasheet, pinout, applications, or equivalent options, key selection factors include its DMP-4 package footprint, 4.5–5.5 V supply range, 6–10 mA supply current in Standard/Legacy mode, ISO26262 ASIL-B safety qualification, and programmable 4/8-point or 16/32-segment transfer characteristic.
Technical Context
The MLX90371GVS-BCC-353-SP integrates on-chip DSP, ADC, and NVRAM to process Triaxis® Hall signals into calibrated position data without external microcontroller intervention. Its architecture includes a 12-bit analog output stage, 12-bit PWM generator, FIR or exponential moving average filtering, and programmable diagnostic modes including broken-wire detection.
This variant uses the DMP-4 package with dual ground pins (Pin 1 and Pin 4), single supply (Pin 2), and single output (Pin 3), configured for Standard/Legacy mode per BCC-353 option code - enabling backward compatibility with prior-generation MLX9036x sensors while supporting full 0–360° rotary or linear displacement decoding via external magnet geometry.

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90363KDC-ABA-000-SP | SOIC-8 package; fixed 4-point linearization; no PWM output; lower temperature grade (-40°C to +150°C) | Limited to legacy rotary potentiometer replacement; lacks stray-field immunity and ASIL-B certification | Only suitable where BCC-353's DMP-4 footprint, extended temperature range, or safety compliance are not required |
| MLX90372GVS-BCC-353-SP | Same DMP-4 package and BCC-353 configuration; adds enhanced diagnostic coverage and improved INL specification | Direct upgrade path for new designs requiring higher diagnostic confidence or tighter linearity (±0.3° vs ±0.5°) | Select when functional safety integrity beyond ASIL-B or sub-degree angular accuracy is mandated |
Compared with MLX90371GVS-BCC-353-SP, MLX90363KDC-ABA-000-SP offers simpler integration but lacks safety certification and modern features, while MLX90372GVS-BCC-353-SP extends diagnostic capability and accuracy at identical form factor - making the latter ideal for next-generation ASIL-B+ systems.

FAQ
What is the package type and lead configuration of MLX90371GVS-BCC-353-SP?
The MLX90371GVS-BCC-353-SP uses the DMP-4 (Dual Mold Package) with STD2 trim-and-form leads at 2.54 mm pitch, as indicated by the "BCC-353" option code. It has four terminals: two ground (VSS), one supply (VDD), and one programmable output (OUT). This PCB-less package is designed for direct soldering onto flex circuits or stamped metal carriers in space-constrained automotive modules.
Does MLX90371GVS-BCC-353-SP support both analog and PWM output modes?
Yes, MLX90371GVS-BCC-353-SP supports both ratiometric analog output (0–100% VDD) and programmable PWM output (150–2000 Hz). The output mode is user-configurable via on-chip NVRAM and does not require external components. In Standard/Legacy mode (BCC-353), the default behavior matches prior-generation MLX9036x timing and transfer characteristics for seamless migration.
What safety certification applies to MLX90371GVS-BCC-353-SP?
MLX90371GVS-BCC-353-SP is certified as an ISO26262 ASIL-B Safety Element out of Context (SEooC). This means it provides documented safety mechanisms-including internal diagnostics, watchdog timers, and memory ECC-that can be integrated into ASIL-B or ASIL-C systems without requiring additional hardware-level redundancy, provided system-level integration follows Melexis' safety manual.
How is stray magnetic field immunity implemented in MLX90371GVS-BCC-353-SP?
MLX90371GVS-BCC-353-SP achieves stray-field immunity in Standard/Legacy mode through Triaxis® signal processing algorithms that separate useful orthogonal field components (BX, BY, BZ) from interfering parallel fields. Unlike single-axis Hall sensors, it rejects uniform external fields up to ±1 T while maintaining full sensitivity to the target magnet's spatial orientation-critical for throttle and pedal sensors near motors or solenoids.
Can MLX90371GVS-BCC-353-SP be programmed in-system after soldering?
Yes, MLX90371GVS-BCC-353-SP supports full in-system programming via its dedicated TEST pin interface using Melexis' PTM (Programmable Triaxis® Module) protocol. Users can configure output mode, transfer curve (4/8-point or 16/32-segment), zero point, filter settings, and diagnostic thresholds without removing the device from the board - enabling final calibration and variant management during end-of-line testing.
