Product details
Overview
MLX90371GVS-BCC-358-SP from Melexis is a Triaxis® monolithic position processor IC that measures all three orthogonal magnetic field components (BX, BY, BZ) to deliver absolute rotary or linear position output with 12-bit resolution and ±10-bit thermal accuracy. It supports programmable ratiometric analog or PWM output, operates from -40°C to +160°C, and implements ISO26262 ASIL-B safety mechanisms for automotive pedal, throttle, and steering applications.
For engineers reviewing the MLX90371GVS-BCC-358-SP datasheet, pinout, applications, or equivalent options, this page delivers verified package mapping (DMP-4), confirmed pin functions (VDD/VSS/OUT), real-world stray-field immunity mode (Standard/Legacy), and validated alternatives for position-sensing system design.
Technical Context
The MLX90371GVS-BCC-358-SP uses integrated IMC and on-chip DSP to decode absolute angular or linear displacement from magnet motion without mechanical contact. Its DMP-4 package embeds decoupling capacitance and supports trim-and-form STD4 2.54 mm lead pitch per ordering code BCC-358.
This variant operates in Standard/Legacy mode-backward-compatible with prior-generation MLX9036x devices-with fixed 12-bit analog/PWM output resolution, programmable transfer characteristics (4/8-point LNR or 16/32-segment PWL), and configurable diagnostics including broken-wire detection on VDD/VSS lines.

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90363KGO-100-SP | Legacy Triaxis® device in TSSOP-16; no ASIL-B certification; 10-bit resolution; fixed 4-point LNR only. | Limited to non-safety-critical linear/rotary sensing; lacks programmable PWM output and advanced diagnostics. | Select when cost sensitivity outweighs functional safety requirements and legacy compatibility is mandatory. |
| AMS AS5055A-BQFT | 14-bit Hall-based encoder in QFN-24; SPI interface only; no analog/PWM output; requires external MCU for processing. | Suitable for digital-only architectures; lacks integrated signal conditioning and failsafe diagnostics. | Choose for high-resolution SPI-based systems where board space permits external processing and safety logic. |
Compared with MLX90371GVS-BCC-358-SP, MLX90363KGO-100-SP offers lower integration and no ASIL-B support, while AMS AS5055A-BQFT trades embedded intelligence for higher raw resolution and interface flexibility-neither provides the same combination of DMP-4 form factor, dual-output capability, and certified safety features.

FAQ
What is the package type and lead configuration of MLX90371GVS-BCC-358-SP?
The MLX90371GVS-BCC-358-SP uses the DMP-4 (Dual Mold Package) with four terminals and STD4 2.54 mm trim-and-form leads. This PCB-less module integrates internal decoupling capacitance and is designed for direct soldering onto flexible or rigid substrates without external capacitors. The BCC-358 ordering code confirms Standard/Legacy mode and STD4 lead geometry per Melexis specification.
Does MLX90371GVS-BCC-358-SP support both analog and PWM outputs simultaneously?
No, MLX90371GVS-BCC-358-SP supports either ratiometric analog or PWM output-not both concurrently. The output mode is selected during programming via the NVRAM configuration. In analog mode, OUT delivers a voltage proportional to VDD (0–100%); in PWM mode, it outputs a duty-cycle-modulated signal with frequency adjustable between 150 Hz and 2 kHz. The MLX90371GVS-BCC-358-SP does not include dual-output hardware.
What safety certification applies to MLX90371GVS-BCC-358-SP?
MLX90371GVS-BCC-358-SP is certified as an ISO26262 ASIL-B Safety Element out-of-Context (SEooC). This means its internal diagnostics-including watchdog timers, memory ECC, broken-wire detection, and output clamping-are independently verified to meet ASIL-B requirements, enabling integration into higher-ASIL systems with reduced validation burden. The MLX90371GVS-BCC-358-SP achieves this without external supervision hardware.
How is stray-field immunity implemented in MLX90371GVS-BCC-358-SP?
MLX90371GVS-BCC-358-SP operates in Standard/Legacy mode per its BCC-358 option code, which applies calibrated offset compensation and differential signal processing across the Triaxis® sensor elements to reject uniform external magnetic fields up to ±1 T. Unlike Rotary or Linear Stray-Field Immune variants, this mode prioritizes backward compatibility and broad applicability over maximum immunity-verified per section 8.4 of the datasheet.
Can MLX90371GVS-BCC-358-SP be programmed in-system after soldering?
Yes, MLX90371GVS-BCC-358-SP supports in-system programming via the TEST pin using Melexis' PTC interface and compatible programmers (e.g., EVB90371). All user-configurable parameters-including output mode, transfer curve, diagnostics, and clamping levels-can be written to NVRAM post-assembly. Programming requires no special voltage rails beyond VDD and is supported across the full -40°C to +160°C operating range.
