Product details
Overview
MLX90371GVS-BCC-101-RX from Melexis is a Triaxis® monolithic position processor IC that senses BX, BY, and BZ magnetic field components to deliver absolute rotary position output with 12-bit resolution, ±1.5° angular accuracy over -40°C to +160°C, and programmable ratiometric analog or PWM output in DMP-4 package. It operates in Rotary Stray-Field Immune Mode for automotive pedal and throttle sensing.
For engineers reviewing the MLX90371GVS-BCC-101-RX datasheet, pinout, applications, or equivalent options, this page delivers verified specifications, DMP-4 terminal mapping, ISO26262 ASIL-B safety compliance, stray-field immunity validation, and real-world use cases in ride height and steering wheel position systems.
Technical Context
The MLX90371GVS-BCC-101-RX implements on-chip DSP-based signal processing of three-axis Hall sensor data to compute absolute angle via piecewise-linear (up to 32-segment) transfer functions. Its architecture includes integrated 12-bit ADC, temperature compensation, and configurable FIR filtering with latency as low as 440 μs.
This variant uses the DMP-4 package with dual ground pins (Pin 1 and Pin 4), single supply (VDD on Pin 2), and open-drain push-pull output (OUT on Pin 3), supporting 4.5–5.5 V operation and delivering 7–12 mA supply current in Rotary Stray-Field Immune Mode.

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute rotary position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90372GVS-BCC-101-RX | Same DMP-4 package and Rotary Stray-Field Immune Mode, but adds 16-bit resolution and extended diagnostic coverage per ISO26262 ASIL-C | Required where higher angular precision (<±0.5°) or ASIL-C decomposition is mandated | Select MLX90372GVS-BCC-101-RX only if system-level safety analysis requires ASIL-C or sub-degree resolution |
| TLE5012BEE1000XUMA1 | Infineon's 3D Hall sensor with 19-bit resolution and SPI interface; no native PWM output; requires external MCU for transfer curve programming | Suitable for designs with existing SPI infrastructure and software-defined calibration workflows | Choose TLE5012BEE1000XUMA1 when leveraging existing MCU resources for advanced diagnostics or multi-sensor fusion |
Compared with MLX90371GVS-BCC-101-RX, the MLX90372 offers higher resolution and ASIL-C readiness at increased cost and complexity, while the TLE5012B shifts calibration burden to firmware and lacks integrated PWM-making MLX90371GVS-BCC-101-RX optimal for cost-sensitive, self-contained analog/PWM systems requiring ASIL-B compliance.

FAQ
What is the operating temperature range of the MLX90371GVS-BCC-101-RX?
The MLX90371GVS-BCC-101-RX is qualified for continuous operation from -40°C to +160°C, meeting AEC-Q100 Grade 0 requirements. This range is validated across all electrical parameters including supply current, latency, and angular accuracy, making it suitable for under-hood automotive placement near engines or inverters where ambient temperatures exceed 125°C.
Does the MLX90371GVS-BCC-101-RX support both analog and PWM outputs simultaneously?
No, the MLX90371GVS-BCC-101-RX supports either ratiometric analog output or PWM output-not both concurrently. The output mode is selected during end-user programming via the NVRAM configuration; switching requires reprogramming the device using Melexis' PTC or PTM tools. The OUT pin delivers one defined signal type per configuration cycle.
How does the Rotary Stray-Field Immune Mode in MLX90371GVS-BCC-101-RX differ from Standard Mode?
The Rotary Stray-Field Immune Mode (BCC-101) uses dedicated magnetic front-end calibration and signal processing to reject external interfering fields up to ±1 mT, whereas Standard Mode (BCC-300) prioritizes sensitivity over immunity. MLX90371GVS-BCC-101-RX achieves ±1.5° accuracy under stray fields that would cause >5° error in Standard Mode, making it essential for EV drivetrain proximity.
What package type and lead form does MLX90371GVS-BCC-101-RX use?
The MLX90371GVS-BCC-101-RX uses the DMP-4 (Dual Mold Package) with STD1 trim-and-form leads spaced at 2.54 mm. It is supplied in face-down tape-and-reel format (RX), enabling automated pick-and-place assembly. The package has no PCB substrate and integrates decoupling capacitance internally, simplifying layout for space-constrained modules.
Is MLX90371GVS-BCC-101-RX certified for functional safety applications?
Yes, the MLX90371GVS-BCC-101-RX is certified as an ISO26262 ASIL-B Safety Element out of Context (SEooC). It includes on-chip diagnostics such as intelligent watchdog (IWD), absolute watchdog (AWD), broken-wire detection, and memory ECC - all documented in Melexis' safety manual - enabling its use in ASIL-B systems without additional hardware safety mechanisms.
