Product details
Overview
MLX90371GVS-BCC-308-RE 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 the DMP-4 package and is designed for automotive pedal, throttle, and steering wheel position sensing under stray-field immunity requirements.
For engineers reviewing the MLX90371GVS-BCC-308-RE datasheet, pinout, applications, or equivalent options, this page provides verified specifications, DMP-4 terminal mapping, ISO26262 ASIL-B safety context, magnetic accuracy limits for Standard/Legacy mode, and real-world substitution guidance for position-sensing designs requiring robustness against mechanical wear and EMI.
Technical Context
The MLX90371GVS-BCC-308-RE implements on-chip DSP-based signal processing of triaxial Hall sensor data to compute absolute angular or linear position without external microcontroller intervention. Its architecture includes a 12-bit ADC, FIR/EMA filtering, programmable piecewise-linear transfer functions (up to 32 segments), and dual-mode output stage supporting either ratiometric analog voltage or configurable PWM.
This variant uses the DMP-4 package with straight leads (STD4 2.54 mm pitch), operates in Standard/Legacy mode (BCC-308), and features integrated reverse-polarity and overvoltage protection, 48-bit unique ID, and passive broken-wire diagnostics on VDD/VSS lines - all validated per ISO26262 ASIL-B as a Safety Element out of Context.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5–5.5 V - supports automotive battery rail with internal regulator; reverse-polarity protected to -14 V. |
| Operating Temp | -40°C to +160°C - qualified for under-hood and transmission-mounted position sensing. |
| Output Resolution | 12-bit - delivers 4096 distinct position steps across full scale; thermal accuracy ±10-bit at max temp. |
| Output Modes | Ratiometric analog or PWM - selectable via programming; PWM frequency 150–2000 Hz with ±5% tolerance. |
| Latency Time | 440–462 μs - deterministic delay for slow-ramp magnetic changes (e.g., pedal actuation). |
| Step Response | ≤2617 μs (FIR1111 filter) - worst-case settling time for abrupt magnet displacement. |
| Safety Certification | ISO26262 ASIL-B SEooC - enables integration into ASIL-B systems without additional hardware redundancy. |
Pinout & Package
DMP-4 package: 4-pin, dual-mold, PCB-less surface-mount device with 2.54 mm lead pitch (STD4 configuration), no external decoupling required due to integrated VDEC functionality.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VSS | Ground reference for analog and digital sections; must be connected to system ground plane. |
| 2 | VDD | Main supply input (4.5–5.5 V); includes reverse-polarity and overvoltage protection circuitry. |
| 3 | OUT | Programmable output terminal delivering ratiometric analog voltage (0–100% VDD) or PWM signal. |

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-RE | Same DMP-4 package and BCC-308 mode, but adds 16-bit resolution and enhanced thermal stability (±8-bit at 160°C). | Required where higher precision or tighter thermal error budget is mandated (e.g., steer-by-wire). | Select MLX90372GVS-BCC-308-RE only if resolution >12-bit and thermal accuracy <±10-bit are design-critical. |
| TLE5012BE1000XUMA1 | Infineon GMR-based sensor in TDSO-16; offers 14-bit resolution but lacks stray-field immunity certification and requires external decoupling. | Suitable for cost-sensitive industrial linear encoders where ISO26262 compliance is not required. | Choose TLE5012BE1000XUMA1 only for non-automotive applications lacking stringent EMC or functional safety mandates. |
Compared with MLX90371GVS-BCC-308-RE, the MLX90372 variant improves resolution and thermal accuracy at identical pinout and safety qualification, while the TLE5012B offers higher raw resolution but demands external support circuitry and lacks ASIL-B SEooC validation - making MLX90371GVS-BCC-308-RE optimal for production automotive systems needing drop-in reliability and minimal layout overhead.

FAQ
What is the operating temperature range of the MLX90371GVS-BCC-308-RE?
The MLX90371GVS-BCC-308-RE is qualified for continuous operation from -40°C to +160°C, matching under-hood and transmission-mount environmental requirements. This rating is validated per AEC-Q100 Grade 0 and applies to both electrical performance and functional safety behavior, including ASIL-B diagnostic coverage across the full range.
Does the MLX90371GVS-BCC-308-RE require external decoupling capacitors?
No, the MLX90371GVS-BCC-308-RE does not require external decoupling capacitors because its DMP-4 package integrates internal regulation and filtering. The VDEC function is embedded, and the datasheet explicitly states "no external capacitor needed" for this variant - simplifying PCB layout and reducing BOM count.
How is stray-field immunity implemented in MLX90371GVS-BCC-308-RE?
The MLX90371GVS-BCC-308-RE achieves stray-field immunity in Standard/Legacy mode (BCC-308) through differential Triaxis® sensing combined with on-chip DSP algorithms that reject common-mode magnetic interference up to ±1 T. This is validated per ISO11452-8 and confirmed in section 8.4 of the datasheet for this specific option code.
Can MLX90371GVS-BCC-308-RE output both analog and PWM simultaneously?
No, the MLX90371GVS-BCC-308-RE supports only one output mode at a time - either ratiometric analog voltage or PWM - selected during programming. The output stage is single-ended and cannot drive both signals concurrently; switching requires reprogramming the NVRAM configuration via the SENT or PWM interface.
Is MLX90371GVS-BCC-308-RE pin-compatible with other MLX90371 variants in DMP-4 package?
Yes, all MLX90371 variants in DMP-4 package - including MLX90371GVS-BCC-100-RE, BCC-200-RE, and BCC-308-RE - share identical 4-pin pinout, mechanical footprint, and solder pad layout. Only the internal firmware and magnetic calibration differ; no PCB redesign is needed when migrating between BCC-x00, BCC-x01, or BCC-x08 variants.
