Product details
Overview
MLX90371GGO-BCC-300-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 MLX90371GGO-BCC-300-SP datasheet, pinout, applications, or equivalent options, this page provides verified package mapping (TSSOP-16), confirmed pin functions, real-world stray-field immune operation in Standard/Legacy mode, and validated alternatives for position-sensing designs requiring functional safety compliance.
Technical Context
The MLX90371GGO-BCC-300-SP uses integrated IMC and on-chip DSP to decode absolute angular or linear displacement from triaxial magnetic field vectors. Its architecture includes dual-die TSSOP-16 isolation (≥4 MΩ), programmable FIR filtering (FIR1/FIR11/FIR1111), and configurable diagnostic modes including active PWM diagnostics and passive broken-wire detection.
This variant implements Standard/Legacy mode (BCC-300), delivering 482 µs refresh rate, 440–462 µs latency, and 150–2000 Hz PWM frequency with ±5% tolerance. It features 48-bit user-programmable ID, 12-bit analog/PWM output, and clamping levels programmable across 0–100% VDD.

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-300-SP | Same TSSOP-16 package and BCC-300 mode, but adds enhanced diagnostic coverage and extended PWM frequency range (100–5000 Hz). | Required where higher diagnostic fault coverage or wider ECU sampling flexibility is mandated by system-level ASIL-C decomposition. | Select MLX90372GGO-BCC-300-SP only if upgraded diagnostics or broader PWM tuning are explicitly needed; otherwise MLX90371GGO-BCC-300-SP offers identical baseline functionality at lower cost. |
| AMS AS5055A-BQFT | Single-die TSSOP-16 Hall sensor with 12-bit SPI output; no analog/PWM dual-mode support; lacks ASIL-B certification and stray-field immunity validation. | Suitable for non-safety-critical industrial encoders or consumer devices where cost and SPI interface dominate over automotive qualification. | Choose AMS AS5055A-BQFT only for cost-sensitive, non-automotive applications without functional safety or high-EMI requirements; not a drop-in replacement for MLX90371GGO-BCC-300-SP. |
Compared with MLX90371GGO-BCC-300-SP, MLX90372GGO-BCC-300-SP extends diagnostic capability and PWM flexibility for higher-ASIL systems, while AMS AS5055A-BQFT offers lower-cost SPI-based position reporting without automotive safety or stray-field immunity guarantees.

FAQ
What is the operating temperature range of the MLX90371GGO-BCC-300-SP?
The MLX90371GGO-BCC-300-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 calipers where conventional potentiometers fail.
Does the MLX90371GGO-BCC-300-SP support both analog and PWM output simultaneously?
No, the MLX90371GGO-BCC-300-SP supports either ratiometric analog output or PWM output-not both concurrently. Output mode is selected during programming via the NVRAM configuration; OUT1 and OUT2 pins can be independently assigned to analog or PWM based on BCC-300 mode settings.
How does the MLX90371GGO-BCC-300-SP achieve stray-field immunity in Standard/Legacy mode?
In BCC-300 Standard/Legacy mode, the MLX90371GGO-BCC-300-SP applies proprietary signal processing algorithms to suppress in-plane magnetic interference up to ±10 mT while preserving Z-axis field sensitivity. This is validated per section 8.4 of the datasheet and does not require external shielding or differential magnet configurations.
What package type is used by the MLX90371GGO-BCC-300-SP?
The MLX90371GGO-BCC-300-SP uses the TSSOP-16 package (GO suffix), featuring dual-die construction with isolated analog/digital domains, 0.65 mm pitch, and an exposed thermal pad. It is distinct from SOIC-8 (DC) and DMP-4 (VS) variants in pin count, isolation capability, and thermal performance.
Is the MLX90371GGO-BCC-300-SP certified for functional safety applications?
Yes, the MLX90371GGO-BCC-300-SP is certified as an ISO26262 ASIL-B Safety Element out-of-Context (SEooC), with documented safety mechanisms including memory ECC, watchdog timers, and diagnostic coverage metrics provided in the safety manual. It is intended for integration into ASIL-B or decomposed ASIL-C systems.
