Product details
Overview
MLX90371GGO-BCC-100-SP from Melexis is a Triaxis® monolithic position processor IC that senses BX, BY, and BZ magnetic field components to deliver absolute rotary position output with 12-bit resolution, ±10-bit thermal accuracy, and programmable ratiometric analog or PWM output. It operates from -40°C to 160°C in TSSOP-16 package and supports stray-field immune operation for automotive pedal and throttle sensing.
For engineers reviewing the MLX90371GGO-BCC-100-SP datasheet, pinout, applications, or equivalent options, this page delivers verified specifications, functional safety context (ASIL-B SEooC), magnetic field immunity mode mapping, and real-world implementation guidance for high-reliability automotive position sensing.
Technical Context
The MLX90371GGO-BCC-100-SP implements Triaxis® Hall technology with on-chip DSP, ADC, and NVRAM to compute absolute angular position from 3D magnetic flux density. Its architecture includes dual-die isolation (TSSOP-16 only), integrated regulator, reverse-polarity and overvoltage protection, and configurable FIR/exponential filtering.
This variant is configured for Rotary Stray-Field Immune Mode – Low-Field Variant (BCC-100), requiring ≤25 mT in-plane field (BX/BY) and ≥100 mT axial field (BZ), with programmable 4-/8-point LNR or 16-/32-segment PWL transfer characteristics and ISO26262 ASIL-B Safety Element out of Context compliance.

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90372GGO-BCC-100-SP | Same package and magnetic mode, but adds EEPROM-based user-programmable ID and extended diagnostic logging. | Required when traceability, firmware version tracking, or enhanced fault recording is mandated by OEM safety requirements. | Select MLX90372GGO-BCC-100-SP if NVRAM write endurance >100k cycles or diagnostic data persistence across power cycles is needed. |
| AMS AS5055A-TS_EK_AB | 14-bit resolution, SPI interface only, no analog/PWM output; requires external MCU for signal conditioning. | Suitable for space-constrained PCBs where digital bus integration outweighs need for direct analog drive capability. | Choose AMS AS5055A-TS_EK_AB only when system already uses SPI infrastructure and can absorb added software overhead for interpolation and diagnostics. |
Compared with MLX90371GGO-BCC-100-SP, the MLX90372 variant extends field-programmability for safety-critical traceability, while the AS5055A shifts architectural responsibility to the host MCU-making the MLX90371 optimal for standalone, low-latency, dual-output automotive position sensing with minimal system dependencies.

FAQ
What magnetic configuration does MLX90371GGO-BCC-100-SP require?
The MLX90371GGO-BCC-100-SP is configured for Rotary Stray-Field Immune Mode – Low-Field Variant, requiring ≤25 mT in-plane (BX/BY) and ≥100 mT axial (BZ) magnetic flux density. This enables accurate 0–360° angle measurement using small, cost-effective magnets while rejecting interference from adjacent sources like motors or solenoids. The BCC-100 option code explicitly defines this magnetic operating point.
Does MLX90371GGO-BCC-100-SP support both analog and PWM outputs simultaneously?
Yes, MLX90371GGO-BCC-100-SP supports independent configuration of its two output channels (OUT1 and OUT2) in TSSOP-16 package: one can be set to ratiometric analog mode while the other operates in PWM mode. This dual-mode capability is enabled by on-chip DSP and NVRAM programming, allowing flexible interface options without external signal conversion circuitry.
Is MLX90371GGO-BCC-100-SP certified for functional safety applications?
Yes, MLX90371GGO-BCC-100-SP is qualified 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-and can be integrated into ASIL-B systems without requiring full re-qualification of the sensor subsystem, reducing development time and validation effort.
What is the purpose of the dual-die structure in the TSSOP-16 package of MLX90371GGO-BCC-100-SP?
The dual-die TSSOP-16 package in MLX90371GGO-BCC-100-SP provides physical isolation between analog and digital domains, achieving >4 MΩ inter-die isolation resistance. This architecture enhances EMC robustness, reduces crosstalk in high-noise automotive environments, and supports independent power sequencing and ground separation-critical for meeting stringent AEC-Q100 and ISO11452-4 emission requirements.
Can MLX90371GGO-BCC-100-SP be reprogrammed in-system after soldering?
Yes, MLX90371GGO-BCC-100-SP supports full in-system programming via its TEST pins using Melexis' PTM (Programmable Triaxis® Module) protocol. Users can configure output mode, transfer characteristic (4/8-point LNR or 16/32-segment PWL), clamping levels, diagnostic settings, and magnetic sensitivity-all without removing the device from the PCB, enabling late-stage calibration and design flexibility.
