Product details
Overview
MLX90371GVS-BCC-150-SP from Melexis is a Triaxis® monolithic position processor IC that senses all three magnetic field components (BX, BY, BZ) to deliver absolute rotary position output with 12-bit resolution, ±0.5° angular accuracy in Rotary Stray-Field Immune Mode, and operation from −40°C to +160°C. It supports programmable ratiometric analog or PWM output, 48-bit unique ID, and ISO 26262 ASIL-B Safety Element out of Context compliance for automotive pedal and throttle sensing.
For engineers reviewing the MLX90371GVS-BCC-150-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 behavior, and validated alternatives for automotive position-sensing designs requiring functional safety and high-temperature reliability.
Technical Context
The MLX90371GVS-BCC-150-SP implements Triaxis® Hall sensing with on-chip DSP, ADC, and NVRAM to decode absolute angle from rotating magnets using in-plane (BX/BY) and vertical (BZ) flux components. Its architecture includes FIR and exponential moving average filtering, programmable clamping, and dual diagnostic modes (active/passive) for broken-wire detection.
This variant uses DMP-4 packaging with straight leads (STD4 2.54 mm pitch), integrates internal decoupling capacitance, and is configured specifically for Rotary Stray-Field Immune Mode with 100 nF output capacitor support. It operates at 18 MHz main clock frequency with 462 μs latency and 2.486 ms worst-case step response under FIR1111 filtering.

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90371GVS-BCC-100-SP | DMP-4 package, Rotary Stray-Field Immune Mode, 100 nF capacitor - identical pinout and core functionality | No difference in target use cases; both rated for −40°C to +160°C and ASIL-B | Select BCC-100 if legacy design validation exists; BCC-150 adds STD4 trim-and-form for improved coplanarity in automated assembly. |
| MLX90372GVS-BCC-150-SP | Successor device with enhanced 14-bit resolution, lower latency (380 μs), and extended magnetic range - not pin-compatible | Requires firmware update and layout revision; suited for next-gen platforms demanding higher precision | Choose MLX90372 only when upgrading system resolution beyond 12-bit or reducing control loop delay below 462 μs. |
Compared with MLX90371GVS-BCC-150-SP, the BCC-100 variant offers identical electrical performance and safety certification but uses standard straight leads instead of STD4-formed leads, while the MLX90372 provides higher resolution and speed at the cost of redesign effort and non-drop-in replacement.

FAQ
What is the operating temperature range of the MLX90371GVS-BCC-150-SP?
The MLX90371GVS-BCC-150-SP is qualified for continuous operation from −40°C to +160°C, making it suitable for under-hood automotive applications such as throttle bodies and brake pedals where ambient temperatures exceed 125°C. This rating is verified per AEC-Q100 Grade 0 stress testing and applies across all output modes and configurations.
Does the MLX90371GVS-BCC-150-SP require external decoupling capacitors?
No, the MLX90371GVS-BCC-150-SP integrates a 100 nF decoupling capacitor within its DMP-4 package, eliminating the need for external ceramic capacitors. This reduces bill-of-materials count and PCB area while maintaining stable regulation under fast transient load conditions typical in automotive power domains.
How does the MLX90371GVS-BCC-150-SP achieve stray-field immunity in rotary mode?
The MLX90371GVS-BCC-150-SP achieves stray-field immunity through proprietary Triaxis® signal processing that separates useful in-plane (BX/BY) and vertical (BZ) magnetic components from orthogonal interference. In Rotary Stray-Field Immune Mode, it rejects fields up to ±1 mT applied perpendicular to the sensing axis, validated per ISO 11452-8 test methods.
What output interfaces does the MLX90371GVS-BCC-150-SP support?
The MLX90371GVS-BCC-150-SP supports two programmable output interfaces: ratiometric analog voltage (0–100% VDD) and PWM (150–2000 Hz). Both are selectable via on-chip NVRAM programming and operate simultaneously with independent scaling, enabling flexible ECU interface options without hardware changes.
Is the MLX90371GVS-BCC-150-SP certified for functional safety applications?
Yes, the MLX90371GVS-BCC-150-SP is certified as an ISO 26262 ASIL-B Safety Element out of Context (SEooC), meaning it provides documented safety mechanisms-including internal diagnostics, memory ECC, and watchdog timers-that can be reused in ASIL-B systems without additional hardware-level verification.
