Product details
Overview
MLX90371GVS-BCC-350-RX 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 and ±10-bit thermal accuracy. It operates from -40°C to +160°C, supports programmable ratiometric analog or PWM output, and implements stray-field immune operation in Standard/Legacy mode for automotive throttle and pedal sensing.
For engineers reviewing the MLX90371GVS-BCC-350-RX datasheet, pinout, applications, or equivalent options, key selection criteria include DMP-4 package compatibility, 4.5–5.5 V supply range, ISO26262 ASIL-B safety element out-of-context qualification, and programmable 4/8-point or 16/32-segment piecewise-linear transfer characteristic.
Technical Context
The MLX90371GVS-BCC-350-RX integrates on-chip DSP, 12-bit ADC, temperature sensor, and NVRAM to perform real-time 3-axis magnetic field processing and output linearization. Its architecture includes configurable FIR filtering, exponential moving average smoothing, and programmable diagnostic modes including broken-wire detection and active diagnostics.
This variant uses the DMP-4 (dual mold, PCB-less) package with straight leads (STD4 2.54 mm pitch), operates in Standard/Legacy mode (BCC-350), and delivers output via a single push-pull OUT pin with clamping and saturation control. It supports 150–2000 Hz PWM frequency or ratiometric analog output with 482 µs refresh rate and 440–462 µs latency.

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-350-RX | Same DMP-4 package and BCC-350 configuration but adds integrated EEPROM for factory-programmed calibration data | Reduces end-of-line calibration time in high-volume assembly; not required for field-programmable designs | Select MLX90372GVS-BCC-350-RX only when pre-loaded calibration or enhanced traceability is mandated |
| MLX90363GDC-ABA-000-RE | SOIC-8 package, legacy 10-bit resolution, no ASIL-B certification, fixed analog output only | Limited to non-safety-critical applications such as HVAC damper control or industrial joysticks | Choose MLX90363GDC-ABA-000-RE only for cost-sensitive, non-automotive designs where safety certification is unnecessary |
Compared with MLX90371GVS-BCC-350-RX, the MLX90372GVS-BCC-350-RX adds factory-programmable memory at identical form-factor and safety grade, while the MLX90363GDC-ABA-000-RE offers lower resolution and no functional safety support - making MLX90371GVS-BCC-350-RX the optimal balance of precision, safety, and field configurability for ASIL-B automotive subsystems.
