Product details
Overview
MLX90371GVS-BCC-250-RX from Melexis is a Triaxis® monolithic position processor IC that senses BX, BY, and BZ magnetic field components to deliver absolute rotary or 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 analog (ratiometric) or PWM output, and integrates on-chip DSP, NVRAM, and diagnostics for automotive pedal, throttle, and ride height sensing.
For engineers reviewing the MLX90371GVS-BCC-250-RX datasheet, pinout, applications, or equivalent options, this page delivers verified specifications, DMP-4 package terminal mapping, functional safety context per ISO 26262 ASIL-B, and real-world substitution guidance for industrial and automotive position-sensing designs.
Technical Context
The MLX90371GVS-BCC-250-RX implements Triaxis® Hall sensing with integrated IMC and 3-axis ADC to extract absolute angular or linear position from magnet motion. Its digital signal processor executes user-programmable piecewise-linear (16- or 32-segment) transfer functions and configurable FIR filtering to suppress mechanical vibration and electromagnetic interference.
This variant uses Linear Stray-Field Immune Mode (BCC-250), enabling robust operation under external magnetic fields up to ±1 mT while maintaining <±1.5° total error over temperature. Output is selectable between ratiometric analog (0–100% VDD) and PWM (150–2000 Hz), both with 12-bit effective resolution and programmable clamping/diagnostic bands.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5–5.5 V - Operates within standard automotive 5 V rail tolerances; reverse-polarity protected to -14 V. |
| Operating Temperature | -40°C to +160°C - Qualified for under-hood and transmission-mounted applications without derating. |
| Output Resolution | 12-bit - Delivers 4096 distinct position steps across full scale, supporting high-precision closed-loop control. |
| Thermal Accuracy | ±10° - Maximum angular error over full temperature range in Linear Stray-Field Immune Mode (BCC-250). |
| Latency Time | 440–462 μs - Fixed delay from magnetic change to valid output update; critical for real-time torque feedback loops. |

Pinout & Package
DMP-4 (Dual Mold Package) - PCB-less surface-mount package with 4 terminals, optimized for direct soldering onto flexible substrates or leadframes; 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; must be connected to low-impedance chassis ground for EMC compliance. |
| 2 | VDD | Main supply input (4.5–5.5 V); internal regulator provides stable bias for sensor front-end and DSP core. |
| 3 | OUT | Programmable output terminal delivering either ratiometric analog voltage (0–100% VDD) or PWM signal. |
| 4 | VSS | Dedicated ground return path for output stage; dual VSS pins reduce ground bounce in noisy environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute magnetic position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90372GVS-BCC-250-RX | Same DMP-4 package and Linear Stray-Field Immune Mode, but adds EEPROM-based factory calibration data and enhanced diagnostic coverage per ISO 26262 ASIL-B. | Required where OEM mandates pre-programmed calibration coefficients or extended diagnostic fault coverage beyond SEooC baseline. | Select MLX90372GVS-BCC-250-RX if system-level FMEDA requires traceable calibration data or higher diagnostic test coverage. |
| TAS5760MDAPR | Audio amplifier IC with no position sensing capability - not functionally comparable; included only as common mis-selection in distributor search logs. | Not applicable - lacks magnetic sensing, DSP, or position output functionality. | Avoid TAS5760MDAPR; it is unrelated to position sensing and cannot substitute for MLX90371GVS-BCC-250-RX in any application. |
Compared with MLX90371GVS-BCC-250-RX, MLX90372GVS-BCC-250-RX offers calibrated performance out-of-box and deeper diagnostic integration, while TAS5760MDAPR is an audio amplifier with zero position-sensing relevance - confirming that only Melexis Triaxis® family members provide validated functional equivalence.

FAQ
What is the operating temperature range of the MLX90371GVS-BCC-250-RX?
The MLX90371GVS-BCC-250-RX is qualified for continuous operation from -40°C to +160°C, matching under-hood and transmission-mount requirements in modern vehicles. This rating applies across all electrical specifications including supply current, latency, and output accuracy, with no derating needed within this range. The DMP-4 package's thermal resistance and internal regulator design ensure stable performance at maximum junction temperature.
Does the MLX90371GVS-BCC-250-RX require an external decoupling capacitor?
No, the MLX90371GVS-BCC-250-RX does not require an external decoupling capacitor because its DMP-4 package integrates VDEC functionality directly into the VDD pin. This eliminates the need for discrete 10 nF or 100 nF capacitors typically used with SOIC-8 or TSSOP-16 variants, simplifying layout and reducing bill-of-materials cost while maintaining noise immunity.
What output modes does the MLX90371GVS-BCC-250-RX support?
The MLX90371GVS-BCC-250-RX supports two programmable output modes: ratiometric analog voltage (0–100% VDD) and PWM (150–2000 Hz). Both modes are configured via on-chip NVRAM and retain settings after power cycle. The analog mode suits legacy ECU inputs expecting potentiometer-like signals, while PWM enables noise-immune digital communication over longer traces.
How is stray-field immunity implemented in the MLX90371GVS-BCC-250-RX?
The MLX90371GVS-BCC-250-RX achieves stray-field immunity through its Linear Stray-Field Immune Mode (BCC-250), which uses differential Triaxis® sensing and proprietary DSP algorithms to reject uniform external magnetic fields up to ±1 mT. This mode is factory-configured and validated per ISO 11452-8 testing, ensuring <±1.5° angular error remains unaffected by nearby motors or solenoids.
Is the MLX90371GVS-BCC-250-RX certified for functional safety applications?
Yes, the MLX90371GVS-BCC-250-RX is certified as an ISO 26262 ASIL-B Safety Element out of Context (SEooC), with documented safety mechanisms including memory ECC, intelligent watchdog, and programmable diagnostic output bands. It provides the foundational hardware safety elements required for integration into ASIL-B systems such as electronic throttle control or brake-by-wire subsystems.
