Product details
Overview
MLX90371GVS-BCC-153-RX from Melexis is a Triaxis® monolithic position processor IC that senses BX, BY, and BZ magnetic field components to deliver absolute rotary position output with 12-bit resolution, ±10° angular accuracy over -40°C to +160°C, and stray-field immunity in rotary mode. It serves as a contactless replacement for potentiometers in automotive throttle and steering wheel position sensing.
For engineers reviewing the MLX90371GVS-BCC-153-RX datasheet, pinout, applications, or equivalent options, key selection criteria include its DMP-4 package, 12-bit analog/PWM programmable output, ISO26262 ASIL-B safety qualification, and rotary stray-field immune magnetic configuration (BCC-153).
Technical Context
The MLX90371GVS-BCC-153-RX implements on-chip DSP-based signal processing of triaxial Hall sensor data to compute absolute angular position without external microcontroller intervention. Its architecture includes integrated ADC, FIR filtering, temperature compensation, and programmable piecewise-linear transfer functions (up to 32 segments) for precise linearization.
This variant operates exclusively in Rotary Stray-Field Immune Mode with STD2 2.54 mm lead form (BCC-153), uses internal voltage regulation with VDD = 4.5–5.5 V, and delivers output via single push-pull OUT pin with configurable analog ratiometric or PWM format at 150–2000 Hz.
Key Specifications

The MLX90371GVS-BCC-153-RX operates from -40°C to +160°C ambient temperature, matching the full automotive under-hood requirement. This rating applies to the DMP-4 package variant and is verified per AEC-Q100 Grade 0 qualification. The device maintains 12-bit output resolution and specified angular accuracy across this entire range, with internal temperature compensation applied in real time by the on-chip DSP.
Does the MLX90371GVS-BCC-153-RX support both analog and PWM outputs?
Yes, the MLX90371GVS-BCC-153-RX supports both programmable ratiometric analog output (0–100% VDD) and digital PWM output (150–2000 Hz). Output mode is configured via on-chip NVRAM during programming; no hardware change is required. The analog output drives loads ≥10 kΩ, while PWM supports push-pull drive into 4.7 kΩ pull-up with 2–11 μs rise/fall times.
What does the "BCC-153" option code signify for the MLX90371GVS-BCC-153-RX?
The "BCC-153" option code identifies three key attributes: "1" = Rotary Stray-Field Immune Mode, "5" = 10 nF internal output capacitor (optimized for low-noise PWM), and "3" = STD2 2.54 mm lead form per Melexis package specification. This configuration is explicitly validated for robust operation in magnetically noisy automotive environments such as throttle bodies and steering columns.
Is the MLX90371GVS-BCC-153-RX certified for functional safety applications?
Yes, the MLX90371GVS-BCC-153-RX is qualified as an ISO26262 ASIL-B Safety Element out of Context (SEooC). It includes hardware diagnostics (broken-wire detection, supply monitoring), fault-tolerant signal processing, and documented safety mechanisms. Full system-level ASIL decomposition requires integration with appropriate safety manager and validation per customer-specific FMEDA.
How is the MLX90371GVS-BCC-153-RX packaged, and what are its mounting considerations?
The MLX90371GVS-BCC-153-RX uses the DMP-4 (Dual Mold Package) - a PCB-less, 4-lead surface-mount device measuring 3.2 × 2.5 mm with STD2 2.54 mm lead pitch. It mounts directly onto flex or rigid PCBs using standard reflow profiles. No thermal pad or heatsink is required; the dual VSS pins provide low-impedance grounding essential for EMC performance in automotive applications.
