Product details
Overview
MLX90365LDC-ABE-000-RE 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 +150 °C in SOIC-8 package.
For engineers reviewing the MLX90365LDC-ABE-000-RE datasheet, pinout, applications, or equivalent options, this page provides verified technical context, pin-level design meaning, real-world application mapping, and validated alternative options for pedal, steering, throttle, and float-level sensing systems.
Technical Context
The MLX90365LDC-ABE-000-RE integrates a Triaxis® Hall front-end sensing all three magnetic field components (BX, BY, BZ), enabling absolute angular or linear position decoding via on-chip DSP and CoRDiC-based rectangular-to-polar conversion. Its 16-bit RISC microcontroller executes firmware with 10 KB ROM, 384 B RAM, and 128 B EEPROM for end-user programmability.
It supports dual output modes - ratiometric analog (0–100% VDD) and programmable PWM (100–1000 Hz) - with configurable filtering (3 modes), clamping, diagnostics (open/short, broken VDD/VSS), and thermal offset correction. The SOIC-8 variant uses single-die architecture with integrated 2.5 V regulator and protection circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5–5.5 V nominal; enables direct connection to standard 5 V automotive rails without external regulation. |
| Analog Output Resolution | 12-bit DAC (0.02–5% VDD/L step); delivers precise ratiometric voltage proportional to magnet angle or stroke. |
| PWM Output Resolution | 12-bit (0.025% duty cycle/LSB); supports high-fidelity digital position reporting with ±0.003–0.035% DC jitter. |
| Operating Temperature | −40 °C to +150 °C; certified for under-hood automotive applications including throttle and steering modules. |
| Magnetic Sensitivity Range | BX/BY up to 70 mT, BZ up to 126 mT; compatible with low-cost NdFeB or ferrite magnets in compact mechanical layouts. |
| Diagnostic Coverage | Open/short circuit detection, broken VDD/VSS monitoring, and field strength diagnostics; reduces need for external safety circuitry. |
| Accuracy (Angular) | ±0.3° intrinsic linearity error (XY axis, factory-trimmed); improves to <±0.1° with multi-point user calibration. |
Pinout & Package
MLX90365LDC-ABE-000-RE is housed in a RoHS-compliant SOIC-8 package with 1.27 mm pitch, optimized for reflow soldering and automotive PCB reliability. Unused pins (Test 0, Test 1, Test 2, Not Used) must be connected to ground per Melexis EMC recommendations.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VDD | Main supply input (4.5–5.5 V); powers internal regulator, DSP, and analog front-end. |
| 2 | Test 0 | Factory test pin; must be grounded for EMC compliance and normal operation. |
| 3 | Test 2 | Factory test pin; must be grounded for EMC compliance and normal operation. |
| 4 | Not Used | No internal connection; requires grounding to minimize EMI coupling. |
| 5 | OUT | Configurable output terminal: ratiometric analog (0–VDD) or PWM (100–1000 Hz). |
| 6 | Test 1 | Factory test pin; must be grounded for EMC compliance and normal operation. |
| 7 | VDIG | Digital supply rail for output stage; internally regulated at 2.5 V; decoupling required. |
| 8 | VSS | Ground reference for analog and digital domains; shared return path for all internal blocks. |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® 3-axis Hall sensing | Measures BX, BY, BZ simultaneously to compute absolute angle or linear displacement without mechanical contact. |
| Programmable transfer characteristic | Supports 4- or 17-point piecewise-linear calibration to compensate for magnet nonlinearity and mechanical tolerances. |
| On-chip diagnostics | Real-time open/short, broken VDD/VSS, and field strength monitoring reduce system-level fault detection latency. |
| Thermal offset correction | Compensates for temperature-induced zero-point drift in both analog and PWM outputs across −40 °C to +150 °C. |
| AEC-Q100 Grade 0 qualification | Validated for automotive safety-critical applications requiring full diagnostic coverage and extended temperature operation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90365LGO-ACD-000-RE | TSSOP-16 dual-die package with full hardware redundancy; higher supply current (2×), isolated diagnostics between dice. | Required for ASIL-B/C systems needing fault-tolerant architecture; not pin-compatible with SOIC-8. | Select when functional safety mandates dual-channel independence and diagnostic separation. |
| MLX90364LDC-ABG-000-RE | Legacy Triaxis® variant with fixed 10-bit analog output, no PWM mode, and no user-programmable transfer curve. | Limited to basic rotary sensing; lacks thermal offset correction and advanced diagnostics of MLX90365. | Choose only for cost-sensitive legacy designs where programmability and diagnostics are not required. |
Compared with MLX90365LDC-ABE-000-RE, the TSSOP-16 MLX90365LGO-ACD-000-RE adds hardware redundancy but increases board area and power; the MLX90364LDC-ABG-000-RE reduces flexibility and accuracy while lowering BOM cost - making the MLX90365LDC-ABE-000-RE optimal for new automotive position-sensing designs requiring programmability, diagnostics, and thermal robustness.

FAQ
What is the operating temperature range of the MLX90365LDC-ABE-000-RE?
The MLX90365LDC-ABE-000-RE operates from −40 °C to +150 °C and is qualified to AEC-Q100 Grade 0. This range covers under-hood automotive environments such as throttle bodies and brake pedals, where sustained high-temperature exposure is common. The device maintains specified accuracy and diagnostic functionality across the full range due to on-chip thermal offset correction.
Does the MLX90365LDC-ABE-000-RE support both analog and PWM output modes?
Yes, the MLX90365LDC-ABE-000-RE supports selectable output modes: ratiometric analog (0–100% VDD) and programmable PWM (100–1000 Hz). The mode is configured via EEPROM programming during end-of-line calibration. Both outputs deliver 12-bit resolution, with PWM offering lower susceptibility to noise in high-EMI environments like engine compartments.
Is the MLX90365LDC-ABE-000-RE pin-compatible with other MLX90365 variants?
No - the MLX90365LDC-ABE-000-RE uses the SOIC-8 package with specific pin assignments (e.g., VDD on Pin 1, OUT on Pin 5), while TSSOP-16 variants (e.g., MLX90365LGO-ACD-000-RE) have different pin counts, functions, and layout. Board redesign is required to switch between SOIC-8 and TSSOP-16 packages; no pin-to-pin compatibility exists.
What diagnostics does the MLX90365LDC-ABE-000-RE provide?
The MLX90365LDC-ABE-000-RE provides open/short circuit detection on the output, broken VDD/VSS monitoring, field strength diagnostics, and programmable diagnostic levels. These features are implemented in hardware and reported via dedicated diagnostic output states, enabling immediate system-level fault response without host MCU intervention.
Can the MLX90365LDC-ABE-000-RE be programmed in-system?
Yes - the MLX90365LDC-ABE-000-RE supports in-system programming of its EEPROM via the SENT or PWM interface using Melexis' PTM (Programmable Transfer Matrix) toolset. Parameters including output mode, transfer curve, clamping thresholds, filter settings, and diagnostic behavior can be updated post-soldering without removing the device from the PCB.
