Overview
MLX90371GVS-BCC-100-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, ±0.5° angular accuracy in Rotary Stray-Field Immune Mode, and ISO26262 ASIL-B safety certification. It operates from -40°C to +160°C, supports ratiometric analog or PWM output, and integrates on-chip DSP for robust stray-field immunity in automotive throttle and pedal sensing.
For engineers reviewing the MLX90371GVS-BCC-100-RX datasheet, pinout, applications, or equivalent options, key selection criteria include its DMP-4 package footprint, 4-pin terminal configuration, 12-bit analog/PWM output programmability, thermal accuracy of 10 bits over temperature, and certified ASIL-B functional safety compliance for safety-critical vehicle subsystems.
Technical Context
The MLX90371GVS-BCC-100-RX implements Triaxis® Hall sensing with integrated IMC to resolve all three orthogonal magnetic field vectors (BX, BY, BZ), enabling contactless absolute angle measurement without external magnets or complex calibration. Its on-chip DSP performs real-time piecewise-linear interpolation (up to 32 segments) and configurable FIR filtering to suppress mechanical vibration and electromagnetic interference.
This variant uses the DMP-4 package with dual-mold construction and no PCB substrate, configured specifically for Rotary Stray-Field Immune Mode (BCC-100), featuring 100 nF internal output decoupling capacitance and face-down tape-and-reel packaging (RX). It delivers 440–462 μs latency and ≤968 μs step response under FIR1 filtering.

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-100-RX | Same DMP-4 package and BCC-100 mode, but adds EEPROM-based 48-bit ID and enhanced diagnostic coverage per ISO26262 Annex G. | Required where unique device identification or extended diagnostic logging is mandated in Tier-1 module designs. | Select MLX90372 if traceability or diagnostic data retention beyond power cycle is needed; otherwise MLX90371GVS-BCC-100-RX suffices for basic ASIL-B position sensing. |
| AMS AS5055A-BQFT | 14-bit resolution, SPI interface only, no native PWM/analog dual-mode output; requires external MCU for signal conditioning. | Used in non-safety-critical consumer or industrial encoders where SPI bus availability and higher resolution outweigh functional safety needs. | Choose AMS AS5055A-BQFT only when SPI interface and >12-bit resolution are prioritized over ASIL-B compliance and single-wire analog/PWM simplicity. |
Compared with MLX90371GVS-BCC-100-RX, the MLX90372 offers enhanced diagnostics and ID storage at marginally higher cost, while the AS5055A demands external processing and lacks ASIL-B certification - making MLX90371GVS-BCC-100-RX optimal for cost-sensitive, safety-compliant automotive rotary sensing.

FAQ
What is the operating temperature range of the MLX90371GVS-BCC-100-RX?
The MLX90371GVS-BCC-100-RX is qualified for operation from -40°C to +160°C ambient temperature, meeting AEC-Q100 Grade 0 requirements. This range covers under-hood locations such as throttle bodies and transmission housings. The device maintains specified angular accuracy and output stability across this full range due to on-chip temperature compensation and calibrated DSP firmware. All electrical parameters in the datasheet are guaranteed within this interval.
Does the MLX90371GVS-BCC-100-RX support both analog and PWM output simultaneously?
No, the MLX90371GVS-BCC-100-RX supports either ratiometric analog voltage output or PWM output - not both simultaneously. The output mode is selected during programming via the NVRAM configuration and remains fixed until reprogrammed. The OUT pin delivers 0–100% VDD analog (with 12-bit resolution) or a 150–2000 Hz PWM signal, depending on the programmed USEROPTION_OUTMODE setting. Hardware pin strapping is not used; configuration is purely non-volatile memory-based.
What package type does the MLX90371GVS-BCC-100-RX use, and how is it mounted?
The MLX90371GVS-BCC-100-RX uses the DMP-4 (Dual Mold Package) - a 4-terminal, PCB-less surface-mount package with STD4 2.54 mm lead pitch and face-down orientation (RX packing form). It is soldered directly onto the host PCB using standard reflow profiles for SnAgCu paste. No carrier board or interposer is required; the die is encapsulated in dual-mold epoxy, and terminals are formed for through-hole or SMT compatibility. Mounting follows Melexis Package Note DMP-4 STD4 specifications.
How is the MLX90371GVS-BCC-100-RX certified for functional safety?
The MLX90371GVS-BCC-100-RX is certified as an ISO26262 ASIL-B Safety Element out of Context (SEooC), meaning its internal safety mechanisms - including lockstep watchdogs, memory ECC, ADC self-test, and diagnostic coverage reporting - have been independently verified. It provides documented FMEDA data, safety manuals, and diagnostic coverage metrics, enabling system integrators to allocate it to ASIL-B or lower safety goals without redesigning safety logic. Certification applies specifically to the BCC-100 configuration and DMP-4 package.
Can the MLX90371GVS-BCC-100-RX be reprogrammed in-system after soldering?
Yes, the MLX90371GVS-BCC-100-RX supports in-system programming (ISP) via the TEST pin using Melexis' PTM (Programmer Tool Module) and standard UART interface. All end-user programmable items - including output mode, transfer characteristic (4/8/16/32-point PWL), filter settings, and diagnostic thresholds - can be updated post-soldering without removing the device. Reprogramming requires 4.5–5.5 V supply, proper timing alignment, and adherence to the PTM protocol; no high-voltage programming voltage is needed.
