Product details
Overview
MLX90371GVS-BCC-353-RX from Melexis is a Triaxis® monolithic position processor IC that senses all three magnetic field components (BX, BY, BZ) to deliver absolute rotary or linear position output with 12-bit resolution, ±10-bit thermal accuracy, and programmable ratiometric analog or PWM output. It operates from -40°C to +160°C in DMP-4 package and is used in automotive throttle, pedal, and steering wheel position sensing where stray-field immunity and ASIL-B functional safety compliance are required.
For engineers reviewing the MLX90371GVS-BCC-353-RX datasheet, pinout, applications, or equivalent options, this page provides verified technical context, real-world design meaning for key specs, validated DMP-4 pin assignments, confirmed safety and magnetic performance boundaries, and two functionally comparable alternatives with documented differences in output configuration and legacy mode behavior.
Technical Context
The MLX90371GVS-BCC-353-RX implements Triaxis® Hall sensing with on-chip DSP, ADC, and NVRAM to compute absolute angular or linear position from 3D magnetic flux vectors. Its architecture includes integrated voltage regulator, reverse-polarity and overvoltage protection, and configurable FIR/exponential filtering.
This variant uses Standard/Legacy Mode (BCC-353), supporting programmable 4-/8-point linearization or 16-/32-segment piecewise-linear transfer characteristics, with selectable analog (ratiometric) or PWM output and 48-bit unique ID storage. It meets ISO 26262 ASIL-B as a Safety Element out of Context.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Temp | -40°C to +160°C - supports under-hood automotive placement without external thermal derating. |
| Supply Voltage | 4.5 V to 5.5 V - compatible with standard 5 V automotive power rails and internal LDO regulation. |
| Output Resolution | 12-bit - delivers 4096 discrete position steps across full scale for high-precision feedback control. |
| Thermal Accuracy | ±10-bit - ensures ≤ ±1% full-scale error drift over full temperature range, critical for closed-loop stability. |
| Latency Time | 440–462 μs - enables real-time position reporting for fast-response systems like electronic throttle control. |
| PWM Frequency | 150 Hz to 2 kHz - adjustable timing allows ECU synchronization and noise rejection in electrically noisy environments. |
| Stray-Field Immunity | Standard/Legacy Mode - maintains accuracy in presence of external magnetic interference per ISO 11452-8 test conditions. |
| Safety Certification | ISO 26262 ASIL-B SEooC - provides certified safety mechanisms (diagnostic coverage, watchdog, memory ECC) for integration into ASIL-B systems. |
Pinout & Package
DMP-4 package: ultra-compact, PCB-less dual-mold construction with 2.54 mm pitch STD2 trim-and-form leads (BCC-353), optimized for direct soldering onto flexible substrates or compact sensor modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VSS | Ground reference for analog and digital sections; must be low-impedance connection to minimize noise coupling. |
| 2 | VDD | Primary supply input (4.5–5.5 V); internal regulator powers core logic and sensing circuitry. |
| 3 | OUT | Configurable output: ratiometric analog (0–100% VDD) or PWM (150–2000 Hz); drives loads up to 10 kΩ. |
| 4 | VSS | Dedicated ground return path; dual VSS pins reduce ground bounce and improve EMC robustness. |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® 3D Hall Sensing | Simultaneous BX/BY/BZ measurement enables true absolute position decoding without mechanical cam or gear constraints. |
| Programmable Transfer Curve | Supports 4/8-point linear or 16/32-segment PWL calibration - eliminates external lookup tables and reduces ECU processing load. |
| On-Chip Signal Processing | DSP-based filtering (FIR or exponential moving average) suppresses mechanical vibration artifacts before output stage. |
| Robust Output Stage | Push-pull driver with clamping, short-circuit protection, and broken-wire diagnostics - reduces need for external protection components. |
| 48-bit Unique ID | Factory-programmed serial number enables traceability, calibration data binding, and anti-counterfeiting in production systems. |

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-353-RX | Same DMP-4 package and Standard/Legacy Mode, but adds enhanced diagnostic coverage and extended PWM frequency range (up to 5 kHz). | Required where higher diagnostic confidence or faster PWM update rates are mandated by system-level ASIL requirements. | Select MLX90372GVS-BCC-353-RX when upgrading legacy designs needing improved fault detection or tighter control loop timing. |
| MLX90363GVS-BCC-353-RX | Legacy-generation Triaxis® device with identical pinout and basic functionality, but lacks ASIL-B certification and advanced filtering options. | Suitable only for non-safety-critical applications where cost sensitivity outweighs functional safety needs. | Choose MLX90363GVS-BCC-353-RX for cost-sensitive industrial or aftermarket systems not requiring ISO 26262 compliance. |
Compared with MLX90371GVS-BCC-353-RX, MLX90372GVS-BCC-353-RX offers higher diagnostic coverage and wider PWM bandwidth at marginally increased cost, while MLX90363GVS-BCC-353-RX provides pin-compatible legacy support without safety certification-making the MLX90371GVS-BCC-353-RX the optimal balance of ASIL-B readiness, programmability, and DMP-4 integration.
