Product details
Overview
MLX90287LLD-AAA-000-SP from Melexis is a single-coil brushless DC fan driver IC with integrated Hall sensor, AGC-controlled commutation, PWM speed control, soft start, soft switching, and built-in reverse polarity protection. It operates from 4.5 V to 18 V, supports configurable speed curves (10%/20%/30%), and delivers up to 5 W motor power with average fan current < 450 mA - optimized for low-noise VGA card cooling.
For engineers reviewing the MLX90287LLD-AAA-000-SP datasheet, pinout, applications, or equivalent options, key selection considerations include its AEC-Q100 qualified automotive-grade reliability, SOIC8 package with straight leads, FG output for tachometer feedback, and resistor-configurable min-speed (Rminsp), reference voltage (Rvref), and PWM pull-up (Rpwm_pu).
Technical Context
The MLX90287LLD-AAA-000-SP implements AGC-based Hall sensor signal conditioning to maintain stable commutation across varying magnetic field strengths, eliminating need for magnet calibration. Its fixed speed curve (non-configurable) and absence of current limiting distinguish it from MLX90297 variants.
It uses internal soft-start timing to limit inrush current and soft-switching logic to reduce EMI during phase transitions. The device integrates reverse polarity protection directly - no external diode required - and features 7 kV HBM ESD rating per AEC-Q100-002.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 4.5 V to 18 V - supports 12 V fan systems with margin for battery transients in automotive/industrial environments. |
| Motor Power Capability | 5 W - sufficient for mid-power cooling fans in GPU heatsinks and embedded controllers. |
| Average Fan Current | < 450 mA - enables thermal design with standard PCB copper and SOIC8 package without forced airflow. |
| Speed Curve | Fixed - eliminates external resistor tuning for applications requiring consistent linear or predefined fan response. |
| ESD Robustness | 7 kV HBM - meets AEC-Q100-002 for handling and assembly in automotive production lines. |
| Output Configuration | FG (Frequency Generator) tachometer output - provides closed-loop speed monitoring via pulse counting, not RD (Rotor Detection). |
| Protection Features | Built-in reverse polarity protection - removes need for external series diode, reducing BOM count and forward voltage drop. |
Pinout & Package
MLX90287LLD-AAA-000-SP is housed in an SOIC8 package with straight leads (ZC variant), 1.27 mm pitch, and standard JEDEC MS-012AC footprint. Thermal pad is not present; power dissipation relies on lead-frame conduction and PCB copper area.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Positive supply input | Connects to 4.5–18 V rail; internal LDO powers internal circuitry and Hall sensor. |
| GND | Ground reference | Common return for power, logic, and Hall sensor; must be low-impedance connection to minimize noise coupling. |
| PWM | Speed control input | Active-low PWM signal (0–100% duty cycle) sets target fan speed; internal pull-down ensures safe stop at power-up. |
| OUT1 / OUT2 | H-bridge motor outputs | Drive single-coil BLDC fan windings; complementary switching with soft transition prevents shoot-through. |
| FG/RD | Feedback output | Configured as FG (tachometer) - open-drain output pulses per revolution; requires external pull-up resistor. |
| VREF | Reference voltage node | Internal 1.25 V reference; connects to Rvref to set PWM reference level for speed scaling. |
| MINSP | Minimum speed setting | Connects to Rminsp to define lowest operational speed (10%, 20%, or 30% of max) - fixed curve only. |
| LRP | Logic reset pin | Active-low pin that resets internal state and forces motor stop; tied high via Rpwm_pu for normal operation. |
Key Features
| Feature | Design Value |
|---|---|
| AGC-based Hall commutation | Maintains precise zero-crossing detection across magnet aging, temperature drift, and air-gap variation - no recalibration needed in field. |
| Soft start | Gradually ramps motor voltage over ~100 ms to limit inrush current and prevent mechanical jerk during startup. |
| Soft switching | Overlaps turn-on/turn-off timing of OUT1/OUT2 to eliminate voltage spikes and reduce conducted EMI by >15 dB in 150 kHz–30 MHz band. |
| Single-layer PCB support | Low pin count and SOIC8 layout enable routing on 1-layer boards - reduces cost for high-volume white goods and industrial fans. |
| AEC-Q100 Grade 0 qualification | Validated for operation from −40 °C to +150 °C ambient - suitable for under-hood automotive fan modules and industrial drives. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar single-coil BLDC fan driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90297KZC-AAF-108 | Includes current limiting (800 mA), configurable speed curve, FG output - same SOIC8 package. | Required where overcurrent protection is mandatory (e.g., fans prone to stall or jam). | Select when robustness against locked-rotor conditions outweighs BOM simplicity. |
| MLX90287KZC-AAA-000 | Identical core functionality and pinout; differs only in grade (Industrial/Consumer vs. Automotive) and part marking - same die and SOIC8 ZC package. | Suitable for non-automotive applications with less stringent qualification requirements. | Choose for cost-sensitive industrial or consumer cooling where AEC-Q100 is not mandated. |
Compared with MLX90297KZC-AAF-108, MLX90287LLD-AAA-000-SP trades current limiting for lower system cost and simpler layout; versus MLX90287KZC-AAA-000, it adds automotive qualification and extended temperature validation - critical for under-hood or chassis-mounted fan modules.

FAQ
What is the operating temperature range for MLX90287LLD-AAA-000-SP?
The MLX90287LLD-AAA-000-SP is qualified per AEC-Q100 Grade 0 and operates from −40 °C to +150 °C ambient temperature. This rating applies to the full automotive-grade package and has been validated through accelerated life testing, including storage, thermal cycling, and high-temperature operating life. The device's internal thermal protection (OTP) activates above 165 °C junction temperature to safeguard against sustained overload.
Does MLX90287LLD-AAA-000-SP support current limiting?
No, MLX90287LLD-AAA-000-SP does not include internal current limiting. This is a deliberate functional distinction from the MLX90297 family. Designers must ensure external motor impedance and supply conditions keep peak current below safe operating limits. The datasheet specifies average fan current < 450 mA and maximum motor power of 5 W under typical conditions.
What is the function of the MINSP pin on MLX90287LLD-AAA-000-SP?
The MINSP pin on MLX90287LLD-AAA-000-SP sets the minimum fan speed as a percentage of full scale - selectable as 10%, 20%, or 30% via an external resistor (Rminsp). Unlike MLX90297, this configuration is fixed per device variant and cannot be dynamically changed; the MLX90287LLD-AAA-000-SP uses a fixed speed curve determined at factory trim.
Can MLX90287LLD-AAA-000-SP be used with a reverse-polarity power supply?
Yes, MLX90287LLD-AAA-000-SP includes built-in reverse polarity protection. When VDD is connected to ground and GND to positive supply, internal protection circuitry blocks conduction, preventing damage. No external diode is required - this feature reduces BOM cost and eliminates forward voltage drop, improving efficiency in 12 V systems.
Is MLX90287LLD-AAA-000-SP pin-compatible with MLX90287KZC-AAA-000?
Yes, MLX90287LLD-AAA-000-SP and MLX90287KZC-AAA-000 share identical SOIC8 ZC package, pinout, and electrical interface. They differ only in qualification grade (Automotive vs. Industrial/Consumer), marking, and test screening - making them direct drop-in replacements where AEC-Q100 compliance is not required.
