Overview
MLX90365LDC-ACD-200-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 ±0.3° angular accuracy at 25°C, thermal offset correction, and open/short diagnostics - deployed in automotive throttle, pedal, and steering wheel position sensing.
For engineers reviewing the MLX90365LDC-ACD-200-RE datasheet, pinout, applications, or equivalent options, this page provides verified package mapping (SOIC-8), confirmed pin functions, real-world diagnostic behavior, preprogrammed transfer characteristic (XXX-200 variant), and validated automotive-grade performance across −40°C to +150°C.
Technical Context
The MLX90365LDC-ACD-200-RE integrates a Triaxis® Hall front-end sensing all three magnetic field components (BX, BY, BZ), a 16-bit RISC DSP for real-time arctangent computation, 12-bit DAC/PWM output stage, EEPROM-based programmability, and on-chip diagnostics including broken-track detection and over/under-voltage monitoring.
It operates from 4.5–5.5 V, draws ≤10 mA (power-saving enabled), supports ratiometric analog or 100–1000 Hz PWM output, and features factory-preprogrammed transfer characteristics (XXX-200 option), thermal offset correction, and 48-bit unique ID - all in a single-die SOIC-8 package rated for automotive temperature range.
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. |
| Operating Temperature | −40°C to +150°C; certified for under-hood and transmission-mounted position sensing applications. |
| Output Resolution | 12-bit (analog/PWM); delivers 0.025% duty cycle or 0.02% VDD/L step size for high-precision closed-loop control. |
| Angular Accuracy | ±0.3° at 25°C (XY axis); achieved via factory-trimmed sensitivity mismatch and intrinsic linearity error compensation. |
| Magnetic Range | BX/BY: ≥70 mT; BZ: ≥126 mT; ensures robust operation with low-cost ferrite magnets in compact mechanical layouts. |
| Diagnostics | Open/short, broken VDD/VSS, field strength, and PWM integrity checks; reduces system-level fault detection latency. |
| Package | SOIC-8; RoHS-compliant, surface-mountable, and compatible with standard reflow profiles per J-STD-020. |
Pinout & Package
MLX90365LDC-ACD-200-RE uses the SOIC-8 package (8-pin, 3.9 mm × 4.9 mm, 1.27 mm pitch) with exposed pad for thermal enhancement and EMC stability. Unused test pins must be grounded per Melexis recommendation to ensure optimal EMI immunity.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VDD | Main supply input (4.5–5.5 V); includes overvoltage protection up to +24 V and reverse voltage clamp at −12 V. |
| 2 | Test 0 | Factory test pin; must be connected to VSS (ground) in final design to prevent noise coupling. |
| 3 | Test 2 | Factory test pin; tied to ground per EMC guidelines to avoid parasitic antenna effects. |
| 4 | Not Used | No internal connection; electrically isolated and requires grounding for EMC compliance. |
| 5 | OUT | Analog ratiometric or PWM output (push-pull or open-drain configurable); drives loads up to 10 kΩ pull-up or 30 mA sink. |
| 6 | Test 1 | Factory test pin; grounded in production to suppress high-frequency emissions. |
| 7 | VDIG | Digital supply rail for internal logic; internally regulated from VDD and decoupled via 100 nF capacitor. |
| 8 | VSS | Ground reference for analog and digital domains; shared return path requiring low-impedance PCB layout. |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® 3-axis Hall sensing | Simultaneous BX, BY, BZ measurement enables true 360° absolute angle or linear stroke decoding without mechanical cam or gear. |
| Preprogrammed transfer curve (XXX-200) | Eliminates end-of-line calibration for target applications - factory-set piecewise-linear mapping reduces manufacturing test time. |
| Thermal offset correction (AxE version) | Compensates for IC-level drift across −40°C to +150°C, limiting angular error contribution to ±0.3° max over full range. |
| On-chip diagnostics | Real-time detection of open-circuit, short-to-rail, broken VDD/VSS, and magnetic field loss - supports ASIL-B functional safety goals. |
| 12-bit dual-output mode | Selectable analog (ratiometric) or PWM output with identical resolution and accuracy - simplifies interface to MCU ADC or timer capture peripherals. |

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 Triaxis® core, but rated for −40°C to +125°C (K grade) and not preprogrammed (XXX-000). | Suitable for under-dash modules where full 150°C rating is unnecessary; requires end-user calibration for transfer function. | Select when thermal budget allows lower grade and programmability is needed post-solder. |
| MLX90365LGO-ACE-000-RE | TSSOP-16 dual-die package with full hardware redundancy, same −40°C to +150°C rating, and thermal offset correction enabled. | Targeted at ASIL-D systems requiring fault-tolerant position feedback; occupies larger PCB area and consumes ~2× current. | Choose only when dual-die redundancy is mandated by functional safety architecture. |
Compared with MLX90365LDC-ACD-200-RE, the KDC-ACD-000 variant trades preprogramming and extended temperature margin for cost and flexibility, while the LGO-ACE-000 variant adds physical redundancy and diagnostic coverage at the expense of size and power - making the LDC-ACD-200-RE optimal for cost-sensitive, high-volume automotive position sensing where precalibrated performance suffices.

FAQ
What does the "-200" suffix indicate in MLX90365LDC-ACD-200-RE?
The "-200" suffix denotes a factory-preprogrammed variant of the MLX90365LDC-ACD-200-RE, where the transfer characteristic (e.g., piecewise-linear mapping, zero-degree point, and clamping thresholds) is configured during final test. This eliminates the need for end-user calibration in target applications such as throttle or pedal position sensing, reducing production test time and firmware complexity.
Is MLX90365LDC-ACD-200-RE pin-compatible with other MLX90365 variants in SOIC-8?
Yes, MLX90365LDC-ACD-200-RE shares identical SOIC-8 pinout and electrical interface with all other DC-package MLX90365 variants (e.g., MLX90365EDC-ACD-000-RE or MLX90365KDC-ABE-000-RE). Pin functions, supply requirements, and output behavior are consistent across temperature grades and option codes within the SOIC-8 footprint.
Does MLX90365LDC-ACD-200-RE support both analog and PWM output simultaneously?
No, MLX90365LDC-ACD-200-RE supports only one output mode at a time - either ratiometric analog voltage or PWM - selected via EEPROM configuration during programming. The "-200" preprogramming fixes this mode per application requirement; switching requires reprogramming, which is not field-accessible without Melexis-approved tools.
What diagnostic capabilities are active by default on MLX90365LDC-ACD-200-RE?
By default, MLX90365LDC-ACD-200-RE enables open/short circuit detection on the OUT pin, under-voltage lockout (MT4V threshold), over-voltage protection (up to +24 V), and broken VDD/VSS monitoring. These diagnostics are hard-coded in firmware and do not require user activation - their status is reflected in dedicated diagnostic output levels per the datasheet's Dsat_lo/Dsat_hi specifications.
Can MLX90365LDC-ACD-200-RE operate with a 3.3 V supply?
No, MLX90365LDC-ACD-200-RE requires a nominal 4.5–5.5 V supply (VDD) and is not specified for 3.3 V operation. Its internal 2.5 V regulator, analog front-end biasing, and output stage are optimized for 5 V rails. Attempting 3.3 V operation will result in power-on reset failure, undefined output behavior, and potential non-compliance with AEC-Q100 stress conditions.
