Product details
Overview
MLX90412KLW-BAH-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 motor 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.
For engineers reviewing the MLX90412KLW-BAH-042-RE datasheet, pinout, applications, or equivalent options, key selection considerations include closed-loop speed accuracy, programmable locked rotor protection, I²C configuration capability, thermal shutdown behavior, and DFN10 3×3 mm wettable flank package compatibility with automated optical inspection.
Technical Context
The MLX90412KLW-BAH-042-RE integrates a Hall-effect position sensor, gate driver, and control logic in a single die, enabling sensorless-less commutation without external rotor position feedback. It supports both open-loop PWM input and closed-loop speed regulation via internal tachometer feedback.
Its adaptive commutation algorithm dynamically adjusts timing across the full speed range (0–30,000 RPM) to maximize efficiency and minimize acoustic noise. Protection features include programmable OVP (up to 40 V), LRP timeout, and thermal shutdown at 150 °C with hysteresis.

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 |
|---|---|---|---|
| DRV10983ZWRGTR | Lacks integrated Hall sensor; requires external rotor position sensing; no I²C interface; only PWM speed control. | Higher BOM cost and layout complexity; unsuitable for space-constrained designs requiring sensor integration. | Choose DRV10983ZWRGTR only if existing design already uses external Hall sensors and I²C programming is unnecessary. |
| MP6532GQ-Z | Supports only open-loop control; no closed-loop speed accuracy spec; no programmable LRP or FG/RD diagnostics. | Lower system-level reliability in variable-load applications like drain pumps or robotic vacuums. | MP6532GQ-Z fits cost-sensitive, fixed-speed fans but cannot replace MLX90412KLW-BAH-042-RE where ±1.5% speed stability or programmable fault response is required. |
Compared with DRV10983ZWRGTR and MP6532GQ-Z, the MLX90412KLW-BAH-042-RE delivers unique value through on-die Hall sensing, closed-loop precision, and field-programmable protections - eliminating external components and enabling faster time-to-market for smart appliance developers.

The MLX90412KLW-BAH-042-RE supports up to 2.2 A continuous motor current with integrated MOSFETs and thermal protection. This enables safe operation of BLDC loads up to 35 W at 24 V, provided PCB copper area and airflow meet Melexis' recommended thermal layout guidelines for the DFN10 package.
Does the MLX90412KLW-BAH-042-RE require an external Hall-effect sensor?
No - the MLX90412KLW-BAH-042-RE integrates a high-sensitivity Hall-effect sensor on-die, eliminating the need for external rotor position sensing. This simplifies mechanical design, reduces bill-of-materials count, and improves reliability in dusty or humid environments where external sensors may degrade.
Can the MLX90412KLW-BAH-042-RE operate in closed-loop speed control mode without I²C communication?
Yes - the MLX90412KLW-BAH-042-RE supports closed-loop speed control using only the PWM input pin; I²C is optional for advanced configuration. Default closed-loop parameters (including ±1.5% accuracy and factory-set LRP timeout) are active at power-on, enabling immediate deployment without programming.
What protection features are programmable on the MLX90412KLW-BAH-042-RE?
The MLX90412KLW-BAH-042-RE supports I²C-programmable locked rotor protection timeout (0.5–5 s), overvoltage threshold (configurable up to 40 V), and FG/RD diagnostic output behavior (tachometer or fault flag). Thermal shutdown and short-circuit protection are fixed internal functions.
Is the MLX90412KLW-BAH-042-RE qualified for use in UL/VDE/CE-certified end equipment?
Yes - the MLX90412KLW-BAH-042-RE is UL/VDE/CE ready per its qualification documentation. Its integrated protections, JEDEC-qualified DFN10 package, and isolation-ready design allow direct use in Class II consumer appliances without additional safety components, accelerating regulatory certification.
