Product details
Overview
MLX90371GVS-BCC-308-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. It operates from 4.5–5.5 V, draws 6–10 mA, and supports stray-field immune operation in Standard/Legacy mode for automotive throttle and pedal sensing.
For engineers reviewing the MLX90371GVS-BCC-308-SP datasheet, pinout, applications, or equivalent options, this page delivers verified specifications, DMP-4 package terminal mapping, ISO26262 ASIL-B safety context, real-world use cases in ride height and steering wheel sensing, and validated alternative part comparisons.
Technical Context
The MLX90371GVS-BCC-308-SP implements Triaxis® Hall sensing with on-chip DSP, ADC, and NVRAM to decode absolute magnet position via 3-axis flux density (BX/BY/BZ) measurement. Its architecture includes a 12-bit analog output stage, 12-bit PWM generator, FIR/exponential filtering, and programmable transfer characteristics (4/8-point LNR or 16/32-segment PWL).
This variant uses Standard/Legacy mode (BCC-308), operates in DMP-4 package with dual ground pins, supports 150–2000 Hz PWM frequency, and features reverse-polarity and overvoltage protection with 48-bit ID storage. Latency is 440–462 μs; step response reaches full settling in ≤2617 μs with FIR1111 filter enabled.

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-308-SP | Same DMP-4 package and BCC-308 configuration but adds enhanced stray-field immunity and extended 16-bit linearization capability | Preferred for new designs requiring higher immunity in proximity to motors or solenoids | Select MLX90372GVS-BCC-308-SP when upgrading legacy systems needing improved EMC robustness without layout change |
| MLX90363GDC-ABA-000-SP | SOIC-8 package, lower temperature grade (-40°C to +150°C), fixed 10-bit output, no programmable transfer characteristic | Suitable for cost-sensitive industrial controls where full ASIL-B compliance is not mandated | Choose MLX90363GDC-ABA-000-SP only for non-automotive applications with simpler calibration needs and SOIC-8 assembly infrastructure |
Compared with MLX90371GVS-BCC-308-SP, MLX90372GVS-BCC-308-SP offers upgraded stray-field rejection and deeper linearization while maintaining pinout and firmware compatibility; MLX90363GDC-ABA-000-SP trades programmability and ASIL-B support for lower cost and SOIC-8 manufacturability - making it unsuitable for safety-critical automotive deployment.
