Product details
Overview
MLX90371GVS-BCC-358-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 analog or PWM output. It operates from -40°C to +160°C, supports stray-field immune operation in Standard/Legacy mode, and is qualified per ISO 26262 ASIL-B as a Safety Element out of Context for automotive pedal, throttle, and steering applications.
For engineers reviewing the MLX90371GVS-BCC-358-RX datasheet, pinout, applications, or equivalent options, this page provides verified technical context, DMP-4 package pin definitions, real-world use cases in ride height and float-level sensing, and two confirmed alternative variants with documented functional and configuration differences.
Technical Context
The MLX90371GVS-BCC-358-RX implements on-chip DSP-based signal processing to decode absolute angular or linear position from triaxial Hall sensor data, using configurable FIR or exponential moving average filtering. Its architecture includes integrated voltage regulation, reverse-polarity and overvoltage protection, and dual-ground (VSS) terminals for noise immunity.
This variant uses the DMP-4 package with STD4 2.54 mm trim-and-form leads and is configured in Standard/Legacy mode (BCC-358), supporting 4/8-point linear or 16/32-segment piecewise-linear transfer characteristics, ratiometric analog or 150–2000 Hz PWM output, and programmable clamping thresholds within 0–100% VDD.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5–5.5 V - Operates across automotive battery range with internal regulator; reverse-polarity protection to -14 V. |
| Operating Temperature | -40°C to +160°C - Qualified for under-hood and transmission-mounted automotive positions. |
| Output Resolution | 12-bit - Delivers 4096 distinct position steps; thermal accuracy maintained at 10-bit level over full temperature range. |
| Output Options | Analog (ratiometric) or PWM (150–2000 Hz) - Configurable via NVRAM; no external components needed for basic operation. |
| Latency Time | 440–462 μs - Fixed delay for slow-ramp magnetic changes; enables deterministic control loop timing in ECU systems. |
| Stray-Field Immunity | Standard/Legacy mode (BCC-358) - Backward-compatible with prior-generation magnetic configurations; no special magnet geometry required. |

Key Features
| Feature | Design Value |
|---|---|
| Triaxis® Sensing Architecture | Simultaneous measurement of BX, BY, BZ enables absolute position decoding without mechanical stops or multi-sensor assemblies. |
| On-Chip DSP Processing | Real-time filtering (FIR or exponential moving average), linearization, and diagnostic computation eliminate need for external microcontroller intervention. |
| Programmable Transfer Characteristic | Supports 4- or 8-point linear or 16-/32-segment piecewise-linear mapping - adapts output curve precisely to mechanical travel profile. |
| Integrated Diagnostics | Active (watchdog, signal integrity) and passive (broken-wire detection on VDD/VSS) diagnostics meet ASIL-B requirements without external circuitry. |
| Robust Output Stage | Push-pull driver with programmable clamping (0–100% VDD) and 30 mA drive capability ensures reliable interfacing with ECU ADCs or PWM inputs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90371GVS-BCC-300-RE | Same DMP-4 package and Standard/Legacy mode, but delivered in standard tape-and-reel (RE) orientation instead of face-down (RX); identical electrical and functional specs. | No difference in target applications; RX variant optimized for pick-and-place with downward-facing die marking visibility. | Select MLX90371GVS-BCC-300-RE if standard reel orientation suffices and face-down placement is not required for vision-based placement verification. |
| MLX90371GDC-BCC-300-RE | SOIC-8 package instead of DMP-4; same Standard/Legacy mode and core functionality, but requires PCB mounting and external decoupling. | Suitable for prototyping or legacy board designs with SOIC footprints; lacks DMP-4's direct-solder flexibility and compactness. | Choose MLX90371GDC-BCC-300-RE only when SOIC-8 mechanical fit or existing layout reuse is mandatory; DMP-4 offers superior thermal and EMI performance in space-constrained modules. |
Compared with MLX90371GVS-BCC-358-RX, the RE-packaged BCC-300 variant offers identical sensing performance but differs in tape orientation for automated assembly, while the SOIC-8 BCC-300 variant trades DMP-4's PCB-less integration for broader layout compatibility-neither is pin-compatible due to differing package geometries and terminal counts.

FAQ
What is the operating temperature range of the MLX90371GVS-BCC-358-RX?
The MLX90371GVS-BCC-358-RX is qualified for continuous operation from -40°C to +160°C, meeting under-hood and transmission-mount environmental requirements. This rating is validated per AEC-Q100 Grade 0 and includes full electrical specification compliance across the range, with thermal accuracy maintained at 10-bit level without external compensation.
Does the MLX90371GVS-BCC-358-RX support both analog and PWM output simultaneously?
No, the MLX90371GVS-BCC-358-RX supports either ratiometric analog output or PWM output-not both concurrently. The output mode is selected during programming via NVRAM configuration and remains fixed until reprogrammed. The OUT pin delivers one defined signal type per configuration, with PWM frequency adjustable from 150 Hz to 2000 Hz.
What does the "BCC-358" option code signify for the MLX90371GVS-BCC-358-RX?
The "BCC-358" option code identifies the MLX90371GVS-BCC-358-RX as a Standard/Legacy mode device in the DMP-4 package with STD4 2.54 mm trim-and-form leads. The "3" denotes Standard/Legacy magnetic configuration, "5" specifies 10 nF internal output capacitor, and "8" indicates STD4 lead form per Melexis package documentation.
Is the MLX90371GVS-BCC-358-RX pin-compatible with other MLX90371 variants?
No, the MLX90371GVS-BCC-358-RX is not pin-compatible with SOIC-8 or TSSOP-16 variants due to its DMP-4 4-pin configuration. While functionally equivalent in Standard/Legacy mode, the DMP-4 package has only VSS, VDD, OUT, and VSS terminals-no test or decoupling pins-requiring dedicated layout and routing distinct from 8- or 16-pin packages.
How is functional safety implemented in the MLX90371GVS-BCC-358-RX?
The MLX90371GVS-BCC-358-RX implements ISO 26262 ASIL-B Safety Element out of Context via on-chip diagnostics including memory ECC, clock monitoring, signal path validation, and passive broken-wire detection on VDD and VSS lines. These mechanisms are fully integrated and require no external components, enabling direct integration into ASIL-B subsystems with documented safety manual support.
