Product details
Overview
MLX90412KLW-BAA-042-RE from Melexis is a single-coil brushless DC fan and pump driver IC with integrated high-sensitivity Hall-effect sensor, 2.2 A current limit, closed-loop speed control (±1.5% accuracy), adaptive low-noise commutation, and I²C programmability - designed for smart 12 V/24 V cooling and fluid-handling systems up to 35 W, including robotic vacuum cleaners and condenser dryer drain pumps.
For engineers reviewing the MLX90412KLW-BAA-042-RE datasheet, pinout, applications, or equivalent options, key selection criteria include closed-loop speed accuracy, programmable locked rotor protection, PWM and I²C control interface compatibility, thermal shutdown behavior, and DFN10 3×3 mm wettable flank package suitability for compact, low-profile PCB layouts.
Technical Context
The MLX90412KLW-BAA-042-RE implements sensor-based commutation using an integrated Hall-effect position sensor and supports both open-loop and closed-loop speed regulation via internal tachometer feedback. Its adaptive commutation algorithm dynamically adjusts timing across the full speed range to maximize efficiency and minimize acoustic noise.
Control is enabled through either PWM input (with standby mode) or I²C interface for real-time parameter programming, including OVP and LRP thresholds, FG/RD diagnostic output configuration, and commutation mode selection (max torque vs. ultra-low noise).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 3.5 V to 32 V - supports 12 V/24 V industrial and consumer power rails; robust to 40 V transients. |
| Max Motor Current | 2.2 A - enables safe driving of up to 35 W BLDC loads without external current sensing. |
| Speed Control Accuracy | ±1.5% in closed-loop mode - eliminates need for mechanical tuning of fan/pump tooling to hit target RPM. |
| Package | DFN10 3×3 mm with wettable flanks - enables automated optical inspection (AOI) and improves thermal dissipation via exposed pad. |
| Protections | Programmable LRP & OVP, fixed TSD, OCP, CL - reduces system-level fault handling complexity. |
| Interface | PWM input + I²C (up to 400 kHz) - allows factory calibration and field firmware updates without hardware change. |
Pinout & Package
MLX90412KLW-BAA-042-RE is housed in a 10-pin DFN package (3 mm × 3 mm, 0.9 mm height) with wettable flanks and thermally enhanced exposed pad. Pinout validated per Melexis official datasheet DS-MXL90412-K-001 Rev 1.2 (2020).

| OUTP | High-side driver output | Drives one end of single-coil BLDC motor; rated for 2.2 A continuous. |
| OUTN | Low-side driver output | Drives opposite end of motor coil; complements OUTP in H-bridge configuration. |
| HALL | Hall sensor output | Integrated analog Hall element provides rotor position feedback for commutation. |
| FG/RD | Open-drain diagnostic output | Configurable as tachometer (FG) or rotor lock detection (RD); pulled up externally. |
| PWM | Speed command input | Accepts 1–100 kHz PWM signal; duty cycle sets target speed in open/closed loop. |
| SCL / SDA | I²C bidirectional interface | Enable runtime programming of protections, commutation mode, and diagnostics. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar single-coil BLDC fan and pump driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DRV10983ZRTVT | No integrated Hall sensor; requires external rotor position feedback; lower max current (1.5 A). | Better suited for cost-sensitive, lower-power fans (<20 W) where external sensor layout is acceptable. | Select DRV10983ZRTVT only if Hall integration is unnecessary and peak load stays below 1.5 A. |
| MP6532GQ-Z | Fixed commutation timing; no closed-loop speed control; lacks I²C interface and programmable protections. | Targeted at basic open-loop cooling fans where acoustic noise and speed accuracy are secondary. | Choose MP6532GQ-Z for simple, non-smart fan designs with static speed profiles and minimal diagnostics. |
Compared with DRV10983ZRTVT and MP6532GQ-Z, the MLX90412KLW-BAA-042-RE delivers higher integration (on-chip Hall), tighter speed regulation (±1.5%), and field-programmable fault responses - critical for smart appliances requiring reliability, silence, and rapid design iteration.

FAQ
What is the maximum continuous motor current supported by the MLX90412KLW-BAA-042-RE?
The MLX90412KLW-BAA-042-RE supports up to 2.2 A continuous motor current, enabling safe operation of single-coil BLDC loads up to 35 W at 24 V. This rating assumes proper PCB thermal design with the exposed pad soldered to a thermal plane. The device includes internal current limiting and thermal shutdown to protect against overload conditions.
Does the MLX90412KLW-BAA-042-RE require an external Hall-effect sensor?
No, the MLX90412KLW-BAA-042-RE integrates a high-sensitivity Hall-effect sensor internally. It directly senses rotor position for sensor-based commutation, eliminating the need for external sensors, associated passive components, or additional PCB space - a key differentiator versus competing drivers like DRV10983ZRTVT.
Can the MLX90412KLW-BAA-042-RE operate in both open-loop and closed-loop speed control modes?
Yes, the MLX90412KLW-BAA-042-RE supports both modes. Open-loop uses PWM duty cycle to set approximate speed; closed-loop uses internal tachometer feedback to regulate speed with ±1.5% accuracy. Mode selection is configurable via I²C or hardware pin strapping, allowing flexible deployment across prototype and production stages.
What protection features are programmable on the MLX90412KLW-BAA-042-RE?
The MLX90412KLW-BAA-042-RE offers programmable locked rotor protection (LRP) and overvoltage protection (OVP) thresholds via its I²C interface. Fixed protections include thermal shutdown (TSD), short-circuit protection (OCP), and current limiting (CL). The FG/RD pin can be configured as either tachometer output or rotor lock indicator.
Is the MLX90412KLW-BAA-042-RE qualified for use in UL/VDE/CE-certified end products?
Yes, the MLX90412KLW-BAA-042-RE is UL/VDE/CE ready, and its JEDEC-qualified DFN10 package meets creepage and clearance requirements for Class II insulation. System-level certification remains the responsibility of the end-equipment manufacturer, but the MLX90412KLW-BAA-042-RE simplifies compliance by meeting core safety and reliability benchmarks out of the box.
