Product details
Overview
MLX90365LDC-ACD-000-RE from Melexis is a Triaxis® Hall-based absolute rotary and linear position sensor IC in SOIC-8 package, delivering 12-bit analog or PWM output with ±0.3° angular accuracy at 25°C, 10-bit thermal accuracy, and AEC-Q100 qualification for automotive pedal and throttle position sensing.
For engineers reviewing the MLX90365LDC-ACD-000-RE datasheet, pinout, applications, or equivalent options, key selection considerations include its programmable multi-point transfer characteristic, on-board diagnostics (open/short, over/under-voltage), thermal offset correction, and dual-output mode flexibility for EOL calibration and functional safety compliance.
Technical Context
The MLX90365LDC-ACD-000-RE integrates a Triaxis® Hall front-end sensing all three magnetic field components (BX, BY, BZ) to compute absolute angular or linear position via on-chip DSP and CoRDiC transformation. Its 16-bit RISC microcontroller executes firmware with 10 KB ROM, 384 B RAM, and 128 B EEPROM for end-user programming of output mode, clamping, filtering, and diagnostics.
It supports two configurable output stages: ratiometric analog (0–100% VDD, 12-bit DAC) or PWM (100–1000 Hz, 12-bit resolution), both with programmable saturation levels, hysteresis filtering (3 modes), and active/passive diagnostic reporting. The SOIC-8 variant uses single-die architecture with VDD, VSS, OUT, VDIG, and test pins routed per Melexis-recommended grounding for EMC.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90365KDC-ACD-000-RE | Higher temperature grade (−40°C to +125°C); identical SOIC-8 pinout and firmware interface | Suitable for under-hood locations near exhaust manifolds or turbochargers where ambient exceeds +85°C | Select when extended thermal range is required; no PCB or firmware changes needed |

FAQ
What output modes does the MLX90365LDC-ACD-000-RE support?
The MLX90365LDC-ACD-000-RE supports two user-programmable output modes: ratiometric analog (0–100% VDD, 12-bit resolution) and pulse-width modulation (100–1000 Hz, 12-bit duty-cycle resolution). Both modes are configured via EEPROM during end-of-line programming and can be selected independently per application requirement without hardware change. The MLX90365LDC-ACD-000-RE's output stage supports push-pull or open-drain configurations with programmable saturation limits.
Is MLX90365LDC-ACD-000-RE qualified for automotive use?
Yes, MLX90365LDC-ACD-000-RE is AEC-Q100 qualified for Grade E (−40°C to +85°C ambient), meeting stress testing requirements for temperature cycling, humidity, mechanical shock, and ESD. It is designed for automotive subsystems including pedal position, steering angle, and throttle control, and supports functional safety development per ISO 26262 up to ASIL-B through integrated diagnostics and thermal compensation. The MLX90365LDC-ACD-000-RE also features 48-bit unique ID for full traceability.
How is magnetic field sensitivity calibrated in MLX90365LDC-ACD-000-RE?
Magnetic sensitivity calibration in MLX90365LDC-ACD-000-RE is performed via end-user programmable parameters stored in EEPROM, including MAPXYZ (field axis mapping), SMISM/k (gain mismatch correction), and GAINMIN/GAINMAX (dynamic range adjustment). Factory-trimmed values provide baseline accuracy, but final calibration occurs during EOL programming using known mechanical positions and applied fields. The MLX90365LDC-ACD-000-RE supports up to 17-point piecewise-linear transfer function definition to compensate for magnet and mechanical nonidealities.
Does MLX90365LDC-ACD-000-RE include built-in diagnostics?
Yes, MLX90365LDC-ACD-000-RE integrates comprehensive on-chip diagnostics: open/short detection on OUT, over/under-voltage monitoring on VDD, broken VDD/VSS detection, field strength validation, and PWM integrity checking. Diagnostic status is reported via dedicated output levels (e.g., BVSSPD, Dsat_lo) and configurable DIAG pin behavior. These features reduce external monitoring components and support ASIL-B fault detection coverage. All diagnostics are active during normal operation and do not require host MCU intervention-enabling autonomous safety checks within the MLX90365LDC-ACD-000-RE itself.
What is the role of VDIG in MLX90365LDC-ACD-000-RE?
VDIG is the dedicated digital supply rail for the MLX90365LDC-ACD-000-RE's internal logic-including the 16-bit RISC microcontroller, EEPROM interface, and digital output stage. It is internally regulated from VDD but requires external decoupling (typically 100 nF ceramic) to suppress switching noise that could affect analog signal integrity. Separating VDIG from VDD improves ADC accuracy and PWM timing stability. In the MLX90365LDC-ACD-000-RE SOIC-8 package, VDIG is assigned to pin 7 and must be decoupled locally per Melexis layout guidelines.
