Product details
Overview
MLX90371GVS-BCC-251-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 in Linear Stray-Field Immune Mode, and programmable ratiometric analog or PWM output. It operates from -40°C to +160°C in the DMP-4 package and is used in automotive throttle, pedal, and ride height sensing.
For engineers reviewing the MLX90371GVS-BCC-251-SP datasheet, pinout, applications, or equivalent options, key selection criteria include stray-field immunity mode (BCC-251 = Linear), DMP-4 package compatibility, 4.5–5.5 V supply operation, ISO26262 ASIL-B compliance, and programmable transfer characteristic configuration.
Technical Context
The MLX90371GVS-BCC-251-SP implements Triaxis® Hall sensing with on-chip DSP, ADC, and NVRAM to compute absolute position from 3-axis magnetic flux density. Its architecture includes a 12-bit analog output stage and a 12-bit PWM generator, both configurable via end-user programming.
This variant uses Linear Stray-Field Immune Mode (BCC-251), requiring specific magnetic field gradients along X/Y axes and defined Z-field magnitude per datasheet Section 8.3. It supports 4/8-point LNR or 16/32-segment PWL transfer functions, with thermal accuracy of ±10 LSB over full temperature range.
Key Specifications

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-201-SP | Same DMP-4 package and Linear Stray-Field Immune Mode, but uses 100 nF output capacitor (BCC-201 vs. BCC-251's 10 nF). | Higher output filter capacitance yields slower slew rate (35 V/ms vs. 120 V/ms), limiting use in fast-response systems like active suspension. | Select BCC-201 only when lower bandwidth and reduced EMI are prioritized over response time. |
| MLX90372GVS-BCC-251-SP | Successor generation with identical pinout, same DMP-4 package, and enhanced 14-bit resolution; retains BCC-251 Linear Stray-Field Immune Mode. | Offers improved thermal accuracy (±5 LSB vs. ±10 LSB) and extended diagnostic coverage, but requires firmware revalidation. | Choose MLX90372GVS-BCC-251-SP for new designs targeting higher precision; MLX90371GVS-BCC-251-SP remains optimal for legacy qualification continuity. |
Compared with MLX90371GVS-BCC-251-SP, BCC-201 trades bandwidth for filtering, while MLX90372GVS-BCC-251-SP upgrades resolution and diagnostics without changing mechanical or electrical interface - enabling drop-in replacement only after functional safety re-assessment.
