Product details
Overview
MLX90371GVS-BCC-258-RX from Melexis is a Triaxis® monolithic position processor IC that senses all three magnetic field components (BX, BY, BZ) to deliver absolute linear position output with 12-bit resolution and ±10-bit thermal accuracy. It operates from -40°C to +160°C, supports programmable linear transfer characteristics (up to 32-segment piecewise-linear), and delivers ratiometric analog or PWM output in DMP-4 package for automotive pedal and throttle position sensing.
For engineers reviewing the MLX90371GVS-BCC-258-RX datasheet, pinout, applications, or equivalent options, this device offers ASIL-B safety compliance, stray-field immunity in Linear mode, configurable diagnostics, and integrated signal processing eliminating external ADC or microcontroller interpolation.
Technical Context
The MLX90371GVS-BCC-258-RX implements on-chip DSP-based angle/position decoding using Triaxis® Hall technology with integrated IMC, enabling robust absolute linear position measurement without mechanical contact. Its architecture includes a 12-bit ADC, FIR and exponential moving average filters, and NVRAM-programmable transfer functions.
This variant uses Linear Stray-Field Immune Mode (BCC-258), features dual ground pins (VSS), single supply (VDD), and push-pull output (OUT) in DMP-4 package - optimized for high-EMC environments where magnetic interference must not degrade linearity or repeatability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Temp | -40°C to +160°C - qualified for under-hood automotive use without derating |
| Supply Voltage | 4.5 V to 5.5 V - compatible with standard 5 V automotive rail; reverse polarity protected |
| Output Type | Selectable ratiometric analog or PWM - enables direct interface to MCU ADC or timer capture without signal conditioning |
| Resolution | 12-bit - provides 4096 distinct position steps over full range |
| Accuracy | ±10-bit thermal accuracy - guarantees ≤ ±1% full-scale error across temperature |
| Latency | 440–462 μs - deterministic response time critical for closed-loop control loops |
| Stray-Field Immunity | Linear mode (BCC-258) - rejects orthogonal interfering fields up to ±1 T per ISO 26262 requirements |
Pinout & Package
DMP-4 package: ultra-compact, PCB-less dual-mold construction with 2.54 mm pitch STD4 trim-and-form leads (BCC-258 suffix), rated for automotive reflow and vibration; no external decoupling capacitor required due to integrated VDEC functionality.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VSS | Ground reference for analog and digital sections; dual VSS pins ensure low-impedance return path |
| 2 | VDD | Primary power input (4.5–5.5 V); internal regulator supplies core logic and sensor front-end |
| 3 | OUT | Push-pull output stage delivering either ratiometric analog voltage (0–100% VDD) or PWM signal (150–2000 Hz) |
| 4 | VSS | Second ground terminal - reduces ground bounce and improves EMC performance in noisy environments |

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-258-RX | Same DMP-4 package and Linear Stray-Field Immune Mode, but adds 48-bit unique ID and enhanced diagnostic coverage per ISO 26262 Annex G | Required where traceability or extended diagnostic fault coverage is mandated beyond ASIL-B base requirements | Select MLX90372GVS-BCC-258-RX only if system-level FMEDA requires additional diagnostic metrics or serialization |
| TLV493DW2B6HTSA1 | 3D Hall sensor with I²C interface; 12-bit resolution but no on-chip transfer function programming or ASIL-B certification | Suitable for non-safety-critical consumer or industrial position feedback where host MCU handles calibration and diagnostics | Choose TLV493DW2B6HTSA1 when cost-sensitive designs can offload signal processing and safety validation to application software |
Compared with MLX90371GVS-BCC-258-RX, the MLX90372 variant adds production traceability and deeper diagnostics without changing pinout or electrical behavior, while the TLV493D requires external firmware development and lacks automotive safety qualification - making MLX90371GVS-BCC-258-RX optimal for drop-in ASIL-B linear position sensing.

FAQ
What is the operating temperature range of the MLX90371GVS-BCC-258-RX?
The MLX90371GVS-BCC-258-RX is qualified for continuous operation from -40°C to +160°C, meeting AEC-Q100 Grade 0 requirements. This range covers under-hood environments including proximity to exhaust manifolds and turbochargers. The device maintains specified accuracy and latency across this full span without derating, and its DMP-4 package is designed for thermal shock resistance during reflow and service life.
Does the MLX90371GVS-BCC-258-RX require external decoupling capacitors?
No, the MLX90371GVS-BCC-258-RX does not require external decoupling capacitors. Its DMP-4 package integrates internal decoupling functionality via the VDEC structure referenced in the datasheet, and the pinout omits a dedicated VDEC pin - unlike SOIC-8 or TSSOP-16 variants. This simplifies PCB layout and eliminates a common source of EMI susceptibility in space-constrained automotive modules.
How is stray-field immunity implemented in the MLX90371GVS-BCC-258-RX?
The MLX90371GVS-BCC-258-RX achieves stray-field immunity through its Linear Stray-Field Immune Mode (BCC-258), which uses differential Triaxis® sensing and proprietary on-chip signal processing to reject orthogonal magnetic interference up to ±1 T. This mode is factory-configured and validated per ISO 11452-8, ensuring reliable operation near high-current cables, solenoids, or electric motors without recalibration or shielding.
Can the MLX90371GVS-BCC-258-RX output both analog and PWM simultaneously?
No, the MLX90371GVS-BCC-258-RX supports either ratiometric analog or PWM output - not both simultaneously. Output mode is selected during programming via NVRAM configuration (USEROPTION_OUTMODE). The analog output provides 0–100% VDD voltage proportional to position; the PWM output delivers 150–2000 Hz signal with duty cycle mapped to position. Switching between modes requires reprogramming the device.
What safety documentation is provided for the MLX90371GVS-BCC-258-RX?
The MLX90371GVS-BCC-258-RX is certified as an ASIL-B Safety Element out of Context (SEooC) per ISO 26262-5:2018. Melexis provides a full safety manual (document MLX90371-SM), FMEDA report, and hardware safety analysis - all accessible under NDA. These documents detail diagnostic coverage, failure modes, and integration guidance for use in ASIL-B or ASIL-C systems when combined with appropriate system-level mechanisms.
