Product details
Overview
MLX90411KZE-BAB-046-RE from Melexis is a single-coil, code-free brushless DC fan driver IC for 5V/12V/24V cooling systems, delivering up to 1 A output current and 15 W power with adaptive low-noise commutation, PWM speed control (±1.5% accuracy), and integrated diagnostics. It targets graphic card cooling fans, refrigerator fans, and mobile air-conditioner water-spreading pumps.
For engineers reviewing the MLX90411KZE-BAB-046-RE datasheet, pinout, applications, or equivalent options, key selection factors include its 3.2–32 V operating supply range, -40 to +125 °C junction temperature rating, UTDFN 2.5 × 2.0 × 0.4 mm package, open-drain FG/RD diagnostics, and UL/VDE/CE-ready certification compliance.
Technical Context
The MLX90411KZE-BAB-046-RE integrates a Hall-effect sensor, gate driver, and power MOSFETs in a single UTDFN package, enabling direct single-coil BLDC motor commutation without external microcontroller or firmware. Its adaptive commutation algorithm dynamically adjusts timing to minimize acoustic noise and mechanical vibration.
It accepts standard PWM input for speed control across three modes - standby, open-loop, and closed-loop - with ±1.5% speed regulation accuracy. Built-in protections include locked rotor detection, thermal shutdown, overvoltage lockout, short-circuit current limiting, and FG/RD diagnostic reporting via open-drain outputs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current | Up to 1 A continuous - supports fan motors requiring ≤15 W at 12 V or 24 V supply. |
| Supply Voltage Range | 3.2 V to 32 V - enables direct compatibility with 5 V, 12 V, and 24 V system rails without external regulators. |
| Speed Control Accuracy | ±1.5% in closed-loop mode - ensures precise RPM regulation under varying load and temperature conditions. |
| Junction Temperature Range | -40 °C to +125 °C - qualified for use in enclosed, thermally demanding environments like graphics cards and refrigerators. |
| Package | UTDFN 2.5 × 2.0 × 0.4 mm - ultra-compact footprint reduces PCB area and improves thermal coupling to heatsink pads. |
| Certifications | UL/VDE/CE ready - simplifies end-product safety certification for consumer and industrial cooling applications. |
Pinout & Package
MLX90411KZE-BAB-046-RE uses the UTDFN-8 (ZE) package: 2.5 mm × 2.0 mm × 0.4 mm body, wettable flanks, JEDEC-qualified, with exposed thermal pad on underside.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Power supply input | Accepts 3.2–32 V; internal LDO powers logic and sensor circuitry. |
| GND | Ground reference | Common return for power, logic, and thermal pad; must be connected to PCB thermal plane. |
| OUTP | High-side power output | Drives one terminal of single-coil BLDC motor; integrated N-channel MOSFET with 1 A rating. |
| OUTN | Low-side power output | Drives opposite motor terminal; integrated N-channel MOSFET complements OUTP for full H-bridge-like commutation. |
| PWM | Speed command input | Active-high TTL/CMOS-compatible signal; configures standby, open-loop, or closed-loop operation. |
| FG | Fan tachometer output | Open-drain pulse output (1–4 pulses per revolution); used for RPM feedback and closed-loop control. |
| RD | Diagnostic output | Open-drain fault indicator - pulls low on locked rotor, overtemperature, overvoltage, or short-circuit events. |
| NC | No connect | Pin 8 is internally unused and must remain unconnected per datasheet. |
Key Features
| Feature | Design Value |
|---|---|
| All-in-one integration | Combines Hall sensor, driver logic, and dual MOSFETs - eliminates need for external controllers, sensors, or discrete FETs, reducing BOM count by ≥7 components. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fan driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90411KLD-BAB-046-RE | Same die, UTDFN-8 (LD) package - 2.5 × 2.0 × 0.4 mm, no leads, wettable flanks. | Identical functionality but requires different reflow profile and solder inspection due to leadless construction. | Select when board space is constrained and automated optical inspection (AOI) supports UTDFN leadless packages. |
| MLX90411KZE-BAB-047-RE | Same ZE package and pinout, but factory-programmed with inverted PWM polarity and alternate FG ratio (2 PPR instead of 4 PPR). | Suitable for systems requiring active-low speed command or simplified tachometer decoding logic. | Select when hardware interface demands inverted PWM input or reduced FG pulse count for MCU resource optimization. |
Compared with MLX90411KZE-BAB-046-RE, the LD variant offers identical performance in a smaller leadless package requiring tighter process control, while the -047 version provides differentiated signal polarity and FG resolution - both serve distinct layout or firmware integration needs without compromising core fan driving capability.

No, the MLX90411KZE-BAB-046-RE is a code-free solution: it operates immediately upon power-up using factory-default parameters optimized for low-noise commutation and stable speed regulation. No external microcontroller, EEPROM, or programming tool is needed - all configuration is handled internally, making MLX90411KZE-BAB-046-RE ideal for rapid deployment in cost-sensitive cooling applications.
What protection features are integrated into the MLX90411KZE-BAB-046-RE?
The MLX90411KZE-BAB-046-RE integrates locked rotor detection, overtemperature shutdown (-40 to +125 °C junction range), overvoltage lockout, short-circuit current limiting, and open-circuit diagnostics on FG and RD pins. These protections are implemented in hardware and activate autonomously - no software or external components are required to safeguard the MLX90411KZE-BAB-046-RE or connected motor.
Can the MLX90411KZE-BAB-046-RE be used with 5 V, 12 V, and 24 V supply rails?
Yes, the MLX90411KZE-BAB-046-RE operates across a 3.2 V to 32 V supply range, making it compatible with 5 V, 12 V, and 24 V systems without external voltage translation or regulation. Its internal architecture maintains consistent PWM speed control accuracy (±1.5%) and thermal protection thresholds across this full range, as verified in the MLX90411KZE-BAB-046-RE datasheet test conditions.
What package type does the MLX90411KZE-BAB-046-RE use, and what are its mounting requirements?
The MLX90411KZE-BAB-046-RE uses the UTDFN-8 ZE package: 2.5 mm × 2.0 mm × 0.4 mm with straight leads and JEDEC-qualified construction. It requires standard SMT reflow per J-STD-020, with GND and thermal pad soldered to a dedicated PCB copper pour for optimal heat dissipation. Pin 8 (NC) must remain unconnected per the MLX90411KZE-BAB-046-RE datasheet.
