Product details
Overview
MLX90371GVS-BCC-300-SP from Melexis is a Triaxis® monolithic position processor IC that senses BX, BY, and BZ magnetic field components to deliver absolute rotary or linear position output with 12-bit resolution, ±10° angular accuracy over -40°C to +160°C, and programmable ratiometric analog or PWM output - deployed in automotive throttle, pedal, and steering wheel position sensing.
For engineers reviewing the MLX90371GVS-BCC-300-SP datasheet, pinout, applications, or equivalent options, this page delivers verified package mapping (DMP-4), confirmed pin functions (VDD/VSS/OUT), ISO26262 ASIL-B safety qualification, stray-field immune legacy mode operation, and real-world timing specs including 462 µs latency and 2.6 ms step response under FIR filtering.
Technical Context
The MLX90371GVS-BCC-300-SP implements on-chip DSP with configurable FIR or exponential moving average filtering, supports 4-/8-point linearization or 16-/32-segment piecewise-linear transfer characteristics, and uses integrated magnetic concentrators for robust 3-axis flux measurement without external magnets. Its DMP-4 package embeds decoupling capacitance and enables PCB-less mounting.
This variant operates in Standard/Legacy Mode (BCC-300), delivering backward compatibility with prior-generation MLX90371 designs while maintaining full programmability of output range, zero-degree point, and clamping thresholds - all stored in on-chip NVRAM with ECC protection and accessible via I²C-compatible serial interface.

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90372GVS-BCC-300-SP | Same DMP-4 package and pinout; adds integrated EEPROM for factory calibration storage and extended diagnostic coverage. | Preferred where end-of-line calibration data must be retained across power cycles without host intervention. | Select MLX90372 when permanent calibration traceability and enhanced ASIL-B diagnostic coverage are required. |
| AMS AS5055A-BQFT | 14-bit resolution, SPI interface only, no analog/PWM dual output; requires external decoupling and lacks ASIL-B certification. | Suitable for non-safety-critical industrial encoders but not drop-in for automotive ASIL-B systems. | Choose AS5055A only for cost-sensitive industrial applications lacking functional safety mandates. |
Compared with MLX90371GVS-BCC-300-SP, the MLX90372 offers higher data retention integrity and broader fault coverage, while the AS5055A trades safety compliance and output flexibility for raw resolution and lower unit cost - making MLX90371GVS-BCC-300-SP the optimal balance of safety, programmability, and automotive qualification.
