Product details
Overview
MLX90371GVD-EAC-300-RX from Melexis is a dual-die Triaxis® absolute position sensor in SMP-4 PCB-less package, delivering ratiometric analog output with 12-bit DAC resolution and ±1° intrinsic XY linearity error over -40°C to +160°C. It decodes rotary or linear magnet motion via BX, BY, BZ field components and supports programmable multi-point calibration for throttle, steering wheel, and valve position sensing.
For engineers reviewing the MLX90371GVD-EAC-300-RX datasheet, pinout, applications, or equivalent options, key selection factors include SMP-4 dual-output architecture, ISO26262 ASIL-B safety element out-of-context compliance, 482 μs refresh rate, 440–462 μs latency, and programmable clamping/transfer characteristics for automotive-grade robustness.
Technical Context
The MLX90371GVD-EAC-300-RX integrates two independent Triaxis® sensor dies in a single SMP-4 mold, each providing a dedicated analog output (OUT1/OUT2) with shared VDD and VSS. Its on-chip DSP performs real-time angle computation from 3-axis magnetic flux density, enabling absolute position decoding without external microcontroller intervention.
It operates in Standard/Legacy mode with factory-calibrated ratiometric analog output, configurable via end-user programmable parameters including 4-/8-point LNR, PWL up to 32 segments, FIR filtering (0–2), and diagnostic thresholds for field-too-low/high detection - all stored in 256 B NVRAM.
Key Specifications

| Resolution | 12-bit DAC (4096 steps), with 10-bit thermal accuracy (±0.2%VDD drift) |
| Linearity Error | ±1° XY intrinsic linearity error; improves with multi-point end-user calibration |
| Refresh Rate | 482 μs - determines minimum sampling interval for real-time control loops |
| Latency Time | 440–462 μs - critical for closed-loop systems requiring deterministic response to slow ramp inputs |
| Operating Temp | -40°C to +160°C - qualified for under-hood automotive applications |

|---|---|---|
| 1: OUT1 | Analog output channel A | Dedicated ratiometric voltage output from first die; enables redundancy or dual-signal monitoring |
| 2: VSS | Ground reference | Common ground for both dies and outputs; must be low-impedance for noise immunity |
| 3: VDD | Supply input | 4.5–5.5 V nominal supply; powers both dies and internal signal chain |
| 4: OUT2 | Analog output channel B | Independent ratiometric output from second die; supports functional safety cross-checking |
| a: TEST1 | Factory test access | Not intended for end-user connection; used during wafer sort and final test |
| b: INPUT | Test input | Reserved for internal diagnostics; no user-accessible function in standard operation |
| c: TEST2 | Factory test access | Not intended for end-user connection; used during wafer sort and final test |

IC Role / Device Role / Timing Role: Solid-state absolute position sensor delivering ratiometric analog output identical to potentiometer interface, eliminating mechanical wear and wiper noise. Use Value: Programmable clamping (CLAMPLOW/CLAMPHIGH) and multi-point calibration allow exact replication of custom potentiometer transfer curves without hardware redesign. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90372GVD-EAC-300-RX | Same SMP-4 dual-die package but supports PWM output mode in addition to analog; higher default filter setting (FIR11 vs FIR1) | Preferred when digital PWM interface is required alongside analog; slightly longer step response (968 μs vs 5008 μs worst-case) | Select MLX90372 if PWM output or enhanced noise filtering is needed; otherwise MLX90371GVD-EAC-300-RX offers optimal analog-only performance and lower latency. |
| MLX90363GSE-ABA-000-SP | Single-die TSOP-6 package; 10-bit resolution; no dual-output capability; lacks ASIL-B SEooC certification | Suitable for cost-sensitive, non-safety-critical linear/rotary sensing where redundancy and automotive qualification are not required | Choose MLX90363 only for non-automotive, single-channel applications with relaxed accuracy and safety requirements; MLX90371GVD-EAC-300-RX is mandatory for ASIL-B systems. |
Compared with MLX90372GVD-EAC-300-RX and MLX90363GSE-ABA-000-SP, the MLX90371GVD-EAC-300-RX uniquely delivers dual analog outputs in an ASIL-B-certified SMP-4 package with lowest latency (440–462 μs) and highest resolution (12-bit), making it the only choice for safety-critical automotive position feedback requiring redundancy and deterministic timing.

FAQ
What is the operating temperature range of the MLX90371GVD-EAC-300-RX?
The MLX90371GVD-EAC-300-RX is qualified for continuous operation from -40°C to +160°C ambient temperature, making it suitable for under-hood automotive applications such as throttle bodies and EGR valves. This rating is validated per AEC-Q100 stress test profiles and includes full electrical specification compliance across the range, including supply current (12–20 mA) and analog output accuracy (±0.2%VDD thermal drift).
Does the MLX90371GVD-EAC-300-RX support functional safety standards?
Yes, the MLX90371GVD-EAC-300-RX is certified as an ISO26262 ASIL-B Safety Element out-of-Context (SEooC), meaning its internal safety mechanisms-including diagnostic monitoring of magnetic field strength, supply voltage, and output saturation-are fully documented and verifiable for integration into ASIL-B systems. The device does not require external safety controllers to meet ASIL-B requirements when used per its safety manual.
How many independent outputs does the MLX90371GVD-EAC-300-RX provide?
The MLX90371GVD-EAC-300-RX provides two independent ratiometric analog outputs (OUT1 and OUT2) via its dual-die SMP-4 configuration. Each output originates from a separate Triaxis® sensor die, enabling redundancy, cross-checking, or differential sensing-critical for automotive safety architectures. Both outputs share VDD and VSS but operate independently in terms of signal processing and calibration.
Can the MLX90371GVD-EAC-300-RX be calibrated for custom mechanical motion profiles?
Yes, the MLX90371GVD-EAC-300-RX supports end-user programmable transfer characteristics including 4-point or 8-point Linearization (LNR) and Piece-Wise Linear (PWL) up to 32 segments. These parameters are stored in 256 B NVRAM and can be configured via Melexis' PTC programming tool to precisely match nonlinear mechanical linkages, cam profiles, or custom potentiometer curves without hardware changes.
What package type is used for the MLX90371GVD-EAC-300-RX?
The MLX90371GVD-EAC-300-RX uses the SMP-4 (Single Mold Package), a PCB-less surface-mount package with four active terminals (OUT1, VSS, VDD, OUT2) and three test points. Designed for direct integration onto housing leadframes or connectors, SMP-4 reduces size and improves mechanical robustness compared to prior PCB-less packages while maintaining compatibility with standard SMT assembly processes.
