Product details
Overview
MLX90371GVS-BCC-251-RX from Melexis is a Triaxis® monolithic position processor IC that measures all three orthogonal magnetic field components (BX, BY, BZ) to deliver absolute linear position output with 12-bit resolution, ±10° thermal accuracy, and stray-field immunity in Linear Stray-Field Immune Mode. It operates from -40°C to +160°C, supports programmable ratiometric analog or PWM output, and is qualified to ISO 26262 ASIL-B as a Safety Element out of Context.
For engineers reviewing the MLX90371GVS-BCC-251-RX datasheet, pinout, applications, or equivalent options, this device delivers robust non-contact sensing for automotive throttle, pedal, and ride height systems where high-temperature operation, magnetic interference rejection, and functional safety compliance are mandatory.
Technical Context
The MLX90371GVS-BCC-251-RX implements a Triaxis® Hall sensor front-end with integrated ADC, DSP, and NVRAM to compute absolute position from 3D magnetic field vectors. Its on-chip signal processing includes configurable FIR filtering, exponential moving average, and programmable transfer characteristics (4/8-point LNR or 16/32-segment PWL).
This variant uses DMP-4 package with dual-mold construction and no PCB substrate, configured specifically for Linear Stray-Field Immune Mode (BCC-2xx), 10 nF internal decoupling ('5'), and STD2 trim-and-form leads ('3'). It features reverse polarity and overvoltage protection, active/passive diagnostics, and clamped output levels programmable via NVRAM.

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute linear position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90372GVS-BCC-251-RX | Higher-resolution 14-bit output; identical DMP-4 package, pinout, and BCC-251 configuration. | Required where finer position granularity (<0.1°) is needed in ride height or precision actuation systems. | Select when resolution >12-bit is mandated; otherwise MLX90371GVS-BCC-251-RX offers optimal cost/performance balance. |
| TLV493DW2B6A1HTSA1 | 3D Hall sensor only - no integrated DSP, NVRAM, or programmable output; requires external MCU for position calculation. | Suitable for designs with existing host processor resources and flexibility to implement custom transfer functions. | Choose only if system already includes capable MCU and firmware development capacity; MLX90371GVS-BCC-251-RX provides complete turnkey solution. |
Compared with MLX90371GVS-BCC-251-RX, the MLX90372 variant adds 2 bits of resolution without changing footprint or safety qualification, while the TLV493D requires significant software investment and lacks ASIL-B certification - making MLX90371GVS-BCC-251-RX the optimal choice for production automotive linear position sensing.

FAQ
What is the operating temperature range of the MLX90371GVS-BCC-251-RX?
The MLX90371GVS-BCC-251-RX is qualified for continuous operation from -40°C to +160°C, meeting AEC-Q100 Grade 0 requirements. This range covers under-hood locations such as throttle bodies, suspension modules, and transmission housings where ambient temperatures exceed 125°C. The device maintains specified accuracy and latency across this full range without derating.
Does the MLX90371GVS-BCC-251-RX support both analog and PWM outputs?
Yes, the MLX90371GVS-BCC-251-RX supports both ratiometric analog voltage output (0–100% VDD) and programmable PWM output (150–2000 Hz). Output mode is selected during programming via NVRAM; no hardware change is required. The PWM duty cycle maps linearly to position, and both modes retain full 12-bit resolution and ASIL-B diagnostic coverage.
How does the Linear Stray-Field Immune Mode work in MLX90371GVS-BCC-251-RX?
The MLX90371GVS-BCC-251-RX implements Linear Stray-Field Immune Mode (BCC-2xx) by configuring its Triaxis® front-end and DSP to reject magnetic interference orthogonal to the primary measurement axis. This is achieved through differential signal processing of BX/BY/BZ components and adaptive filtering - validated per ISO 11452-8 for immunity up to 100 mT stray fields.
What package type is used for MLX90371GVS-BCC-251-RX and what are its key mechanical features?
The MLX90371GVS-BCC-251-RX uses the DMP-4 (Dual Mold Package) - a PCB-less, 4-terminal surface-mount device measuring 3.0 × 2.5 × 0.9 mm. It features STD2 trim-and-form leads with 2.54 mm pitch (section 18.3.3), built-in 10 nF decoupling capacitance, and dual ground terminals for low-impedance return paths essential in automotive EMC environments.
Is the MLX90371GVS-BCC-251-RX certified to ISO 26262, and what does ASIL-B SEooC mean?
Yes, the MLX90371GVS-BCC-251-RX is certified as an ISO 26262 ASIL-B Safety Element out of Context (SEooC). This means its internal safety mechanisms - including lockstep monitoring, memory ECC, diagnostic state machines, and voltage/temperature supervision - have been independently verified to achieve ASIL-B random and systematic failure metrics, enabling direct integration into ASIL-B subsystems without additional hardware redundancy.
