Product details
Overview
MLX90365LDC-ACD-200-SP from Melexis is an AEC-Q100 qualified Triaxis® Hall-effect absolute position sensor IC in SOIC-8 package, delivering 12-bit analog or PWM output with ±0.3° angular accuracy at 25°C, thermal offset correction, and programmable transfer characteristics for rotary or linear position sensing in automotive throttle, pedal, and steering applications.
For engineers reviewing the MLX90365LDC-ACD-200-SP datasheet, pinout, applications, or equivalent options, this page provides verified technical context, validated pin functions, real-world application mappings, and confirmed alternative options for position-sensing system design and sourcing.
Technical Context
The MLX90365LDC-ACD-200-SP integrates a Triaxis® Hall front-end sensing all three magnetic field components (BX, BY, BZ), a 16-bit RISC microcontroller with 10 KB ROM and 384 B RAM, and dual-output stage supporting ratiometric analog (0–100% VDD) or programmable PWM (100–1000 Hz). Its DSP computes absolute angle via CoRDiC-based rectangular-to-polar conversion.
It features on-chip diagnostics including open/short detection, broken-track monitoring, over-voltage protection up to +24 V, under-voltage detection at 3.8–4.2 V, and thermal offset correction calibrated per unit. The preprogrammed ACD-200 variant implements factory-set 4-point piecewise-linear transfer characteristic and default PWM mode.

Pinout & Package
MLX90365LDC-ACD-200-SP uses RoHS-compliant SOIC-8 package (5.0 × 6.2 mm, 1.27 mm pitch) with exposed pad for thermal performance. Pin 1 = VDD, Pin 5 = OUT (analog/PWM output), Pin 8 = VSS (ground). Unused test pins (2, 3, 4, 6, 7) must be tied to ground per EMC guidelines.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VDD | Main supply input (4.5–5.5 V); includes overvoltage protection to +24 V |
| 2 | Test 0 | Factory test pin; must be connected to VSS for EMC compliance |
| 3 | Test 2 | Factory test pin; must be connected to VSS for EMC compliance |
| 4 | Not Used | No internal connection; tie to VSS to minimize EMI |
| 5 | OUT | Configurable output: ratiometric analog (0–100% VDD) or PWM (100–1000 Hz) |
| 6 | Test 1 | Factory test pin; must be connected to VSS for EMC compliance |
| 7 | VDIG | Digital supply domain; internally regulated from VDD; decoupling required |
| 8 | VSS | Ground reference for analog and digital domains; single-point connection recommended |
Key Features
| Feature | Design Value |
|---|---|

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-200-SP | TSSOP-16 dual-die redundant architecture; higher pin count; separate VDD1/VDD2, VSS1/VSS2, OUT1/OUT2 domains | Required for ASIL-D systems needing hardware redundancy; not pin-compatible with SOIC-8 MLX90365LDC-ACD-200-SP | Select when functional safety requires dual-channel independence and fault-tolerant output voting. |
| TLV493DW2B6A1HTSA1 | Infineon 3D Hall sensor; 14-bit I²C output only; no analog/PWM; lower max temp (125°C); no EEPROM programmability | Suitable for cost-sensitive industrial encoders but lacks automotive qualification, diagnostics, and output flexibility | Choose for non-automotive designs where I²C interface and smaller footprint outweigh need for AEC-Q100 or analog output. |
Compared with MLX90365LGO-ACD-200-SP, the MLX90365LDC-ACD-200-SP offers identical core sensing and firmware but in a space-constrained SOIC-8 package without redundancy-ideal for single-channel ASIL-B applications. Versus TLV493DW2B6A1HTSA1, it delivers automotive-grade reliability, dual-output modes, and field-programmable calibration essential for production vehicle deployment.

FAQ
What is the operating temperature range of the MLX90365LDC-ACD-200-SP?
The MLX90365LDC-ACD-200-SP is rated for −40°C to +150°C ambient operation and qualified per AEC-Q100 Grade 0. This enables direct mounting in high-heat zones such as engine compartments or near exhaust manifolds without derating. Its thermal offset correction algorithm actively compensates for drift across the full range, maintaining <0.5° total angular error in real-world automotive environments.
Does the MLX90365LDC-ACD-200-SP support both analog and PWM outputs simultaneously?
No-the MLX90365LDC-ACD-200-SP supports only one output mode at a time, selected during factory programming. The ACD-200 variant is preconfigured for PWM output by default. To use ratiometric analog output, the device must be reprogrammed via Melexis' PTC interface using the MLX90365 Programming Tool. Output mode selection is stored in EEPROM and persists through power cycles.
How does the MLX90365LDC-ACD-200-SP achieve absolute position measurement without a reference point?
The MLX90365LDC-ACD-200-SP uses Triaxis® Hall technology to measure all three orthogonal magnetic field components (BX, BY, BZ) simultaneously. Its on-chip DSP applies CoRDiC-based rectangular-to-polar conversion to compute absolute angle from BX and BY, while BZ provides axial position or tilt compensation. This eliminates reliance on index pulses or homing routines required by incremental encoders.
What diagnostic capabilities does the MLX90365LDC-ACD-200-SP provide?
The MLX90365LDC-ACD-200-SP integrates open/short circuit detection on the output pin, supply rail monitoring (under-voltage at 3.8–4.2 V, over-voltage up to +24 V), broken-track diagnostics for VSS/VDD disconnection, and magnetic field strength validation. Diagnostic status is reported via dedicated output levels or encoded in PWM duty cycle, enabling ECU-level fault classification per ISO 26262 requirements.
Is the MLX90365LDC-ACD-200-SP pin-compatible with other MLX90365 variants?
Yes-MLX90365LDC-ACD-200-SP shares identical SOIC-8 pinout and electrical behavior with all other DC-package variants (e.g., MLX90365LDC-ACD-000-SP). However, it is not pin-compatible with GO-package (TSSOP-16) variants due to differing pin count, assignment, and dual-die architecture. PCB layout must match the SOIC-8 footprint and grounding scheme specified in Melexis Application Note AN-012.
