Product details
Overview
MLX90365EDC-ACD-000-SP from Melexis is an AEC-Q100 qualified absolute rotary and linear position sensor IC based on Triaxis® Hall technology, delivering 12-bit analog or PWM output with 10-bit thermal accuracy, open/short diagnostics, and automotive-grade operation from −40 °C to +85 °C in SOIC-8 package. It decodes absolute angular position (0–360°) or linear displacement using orthogonal and parallel magnetic field components (BX, BY, BZ), enabling non-contacting potentiometer replacement in throttle and pedal sensing.
For engineers reviewing the MLX90365EDC-ACD-000-SP datasheet, pinout, applications, or equivalent options, this page provides verified technical context, SOIC-8 pin mapping, programmable transfer characteristic details, diagnostic behavior, and validated automotive alternatives for pedal, steering, and float-level sensing designs.
Technical Context
The MLX90365EDC-ACD-000-SP integrates a Triaxis® Hall front-end sensing all three magnetic flux components (BX, BY, BZ), a 16-bit RISC microcontroller running at 10 MHz (2.5 MIPS), 12-bit DAC for analog output, and 12-bit PWM generator. Its DSP performs real-time coordinate rotation (CoRDiC) to compute absolute angle or linear position from raw sine/cosine signals.
It supports end-user programming of output mode (analog ratiometric or PWM), multi-point piecewise-linear transfer characteristics (4- or 17-point), clamping thresholds, filter settings (3 modes), and diagnostic configurations including open/short detection and broken-track diagnostics. Thermal offset correction is not enabled in the ACD-000 variant per datasheet Section 14.2.7.

Applications
| Throttle Position Sensing | Pedal Position Sensing |
|---|---|
|
Use Scenario: Monitoring accelerator pedal angle in gasoline/diesel powertrain control units to determine torque demand. IC Role / Device Role / Timing Role: Absolute rotary position sensor providing continuous 0–100% throttle signal with <5 ms startup latency. Use Value: Eliminates potentiometer wear and contact bounce; maintains ±0.98° linearity error after factory calibration for closed-loop air-fuel ratio control. |
Use Scenario: Detecting brake or clutch pedal travel in electronic braking systems (EBS) and automated manual transmissions (AMT). IC Role / Device Role / Timing Role: Linear position transducer converting pedal stroke into ratiometric analog voltage or PWM duty cycle. Use Value: Enables fail-safe dual-signal redundancy when paired with second MLX90365; open/short diagnostics support ISO 26262 ASIL-B monitoring. |
| Steering Wheel Angle Sensing | Float-Level Fuel Sensing |
|
Use Scenario: Measuring absolute steering wheel rotation for electric power steering (EPS) assist torque calculation and lane-keeping assist (LKA). IC Role / Device Role / Timing Role: High-accuracy rotary encoder reporting 0–720° (2-turn) or multi-turn position via magnetic ring coupling. Use Value: Delivers <±0.3° phase error at 25 °C and <0.01°/°C thermal drift - critical for torque vectoring and ADAS stability control. |
Use Scenario: Tracking fuel level in automotive tanks using a float-attached diametrically magnetized ring magnet.

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90365KDC-ACD-000-RE | Same SOIC-8 package and ACD-000 firmware, but K-suffix rated for −40 °C to +125 °C ambient. | Required for transmission control modules or turbocharger actuators where junction temperature exceeds 105 °C. | Select when operating ambient exceeds 85 °C; otherwise MLX90365EDC-ACD-000-SP is optimal for cost-sensitive body electronics. |
| MLX90365LDC-ACE-000-RE | L-suffix (−40 °C to +150 °C) with ACE-000 option enabling thermal output offset correction - not present in ACD-000. | Suitable for high-temperature exhaust gas recirculation (EGR) valves where thermal drift dominates accuracy budget. | Choose only if thermal offset correction is mandatory; ACE-000 adds calibration complexity and cost versus standard ACD-000. |
Compared with MLX90365EDC-ACD-000-SP, the KDC variant extends temperature range without changing pinout or firmware, while the LDC-ACE offers superior thermal stability at the cost of added programming steps and higher unit price - making the EDC-ACD-000 optimal for cabin, chassis, and non-powertrain applications.

FAQ
What is the operating temperature range of the MLX90365EDC-ACD-000-SP?
The MLX90365EDC-ACD-000-SP is rated for an ambient operating temperature range of −40 °C to +85 °C (Grade E). This specification is validated per AEC-Q100 stress testing and applies to the SOIC-8 packaged device with ACD-000 firmware configuration. Junction temperature limits remain within safe operating area under typical PCB thermal dissipation conditions.
Does the MLX90365EDC-ACD-000-SP support both analog and PWM outputs simultaneously?
No, the MLX90365EDC-ACD-000-SP supports only one active output mode at a time - either ratiometric analog voltage or PWM - selected during end-of-line programming. The OUT pin is configured exclusively for the chosen mode; simultaneous dual-output operation is not supported in the ACD-000 variant.
Is thermal offset correction enabled in the MLX90365EDC-ACD-000-SP?
No, thermal offset correction is not enabled in the MLX90365EDC-ACD-000-SP. Per datasheet Section 14.2.7, this feature is exclusive to ACE-xxx option codes. The ACD-000 variant uses fixed factory calibration and relies on its 10-bit thermal accuracy spec (±1 LSB per 10 °C) without dynamic compensation.
What diagnostic functions are implemented in the MLX90365EDC-ACD-000-SP?
The MLX90365EDC-ACD-000-SP implements open-circuit, short-circuit, under-voltage, over-voltage, and broken-track diagnostics. Diagnostic status is reported via defined saturation levels on the OUT pin (e.g., Dsat_lo/Dsat_hi) and can be interpreted by host ECUs without additional hardware. All diagnostics are active during normal operation and startup.
Can the MLX90365EDC-ACD-000-SP be used in redundant safety architectures?
Yes, the MLX90365EDC-ACD-000-SP supports functional redundancy when paired with a second identical device. While it lacks internal dual-die redundancy (a feature reserved for TSSOP-16 GO-package variants), its deterministic diagnostics, AEC-Q100 qualification, and predictable failure modes enable ASIL-B compliant system-level redundancy in pedal, throttle, and steering applications.
