Product details
Overview
MLX90371GVS-BCC-350-RE 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 operates from -40°C to +160°C, supports programmable analog (ratiometric) 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-350-RE datasheet, pinout, applications, or equivalent options, this device delivers ASIL-B safety compliance, on-chip DSP-based signal processing, and DMP-4 package integration for direct PCB mounting without external decoupling capacitors.
Technical Context
The MLX90371GVS-BCC-350-RE uses integrated magnetic concentrators (IMCs) and a 12-bit ADC to digitize triaxial Hall sensor outputs, feeding them into a dedicated DSP for real-time angle calculation using arctangent algorithms. Its firmware implements configurable FIR filtering, exponential moving average, and programmable clamping to suppress noise and transient errors.
This variant operates in Standard/Legacy Mode (BCC-350), delivering backward compatibility with prior-generation MLX9036x devices while maintaining full 12-bit analog/PWM output capability, 482 µs refresh rate, and diagnostic features including broken-wire detection on VDD/VSS and active diagnostics via OUT pin.

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90363GDC-ABB-100-SP | SOIC-8 package; legacy Triaxis® architecture; no ASIL-B certification; fixed 10-bit output resolution | Limited to non-safety-critical applications; lacks programmable PWL and advanced diagnostics | Select only for cost-sensitive legacy designs where ASIL-B and 12-bit resolution are not required |
| TLV493DW2B6HTSA1 | Infineon 3D Hall sensor IC; I²C digital interface; 12-bit output; no integrated DSP or ASIL-B qualification | Requires external microcontroller for angle computation; unsuitable for direct analog/PWM replacement | Choose when system-level flexibility and digital bus integration outweigh need for self-contained position output |
Compared with MLX90371GVS-BCC-350-RE, the MLX90363 offers lower cost but no functional safety certification or on-chip processing, while the TLV493DW2B6HTSA1 provides digital interface flexibility but shifts computational burden to host MCU and lacks automotive-grade diagnostic coverage.

FAQ
What is the operating temperature range of the MLX90371GVS-BCC-350-RE?
The MLX90371GVS-BCC-350-RE is qualified for continuous operation from -40°C to +160°C, meeting AEC-Q100 Grade 0 requirements. This range supports placement in high-heat zones such as engine compartments and transmission housings without thermal derating. The device maintains specified accuracy and latency performance across the full range, validated per Melexis qualification profile.
Does the MLX90371GVS-BCC-350-RE require external decoupling capacitors?
No, the MLX90371GVS-BCC-350-RE uses the DMP-4 package with integrated decoupling capacitance, eliminating the need for external VDD bypass capacitors. This simplifies PCB layout, reduces bill-of-materials count, and improves reliability by removing solder joint failure points associated with discrete capacitors.
How does the MLX90371GVS-BCC-350-RE achieve stray-field immunity in Standard/Legacy Mode?
In Standard/Legacy Mode (BCC-350), the MLX90371GVS-BCC-350-RE applies calibrated gain and offset correction to its triaxial measurements, rejecting common-mode magnetic interference while preserving the useful signal from the target magnet. This is implemented in firmware and requires no external hardware changes or magnetic shielding.
What output interfaces does the MLX90371GVS-BCC-350-RE support?
The MLX90371GVS-BCC-350-RE supports two configurable output modes: ratiometric analog voltage (0–100% VDD) and PWM (150–2000 Hz). Output mode selection is programmed into NVRAM during final test and remains persistent through power cycles. No external components are needed for either interface.
Is the MLX90371GVS-BCC-350-RE certified for functional safety applications?
Yes, the MLX90371GVS-BCC-350-RE is certified as an ASIL-B Safety Element out of Context (SEooC) per ISO 26262. It includes diagnostic features such as broken-wire detection on VDD/VSS, internal watchdog timers, and memory ECC, enabling integration into ASIL-B or ASIL-C systems when used with appropriate system-level safety mechanisms.
