Product details
Overview
MLX90412KLW-BAH-025-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. It operates from 3.5 V to 32 V (robust to 40 V) and supports up to 35 W motor loads - ideal for smart window air-conditioners, toilet pumps, robotic cleaners, and condenser dryer drain pumps.
For engineers reviewing the MLX90412KLW-BAH-025-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 exposed-pad package compatibility with automated optical inspection.
Technical Context
The MLX90412KLW-BAH-025-RE implements sensor-based commutation using an integrated Hall-effect sensor and supports both open-loop and closed-loop speed control modes. Its adaptive commutation algorithm dynamically adjusts timing across the full speed range to maximize efficiency and minimize acoustic noise.
Protections include programmable locked rotor detection, overvoltage protection (OVP), overcurrent protection (OCP), current limiting, and thermal shutdown (TSD). Diagnostics are reported via an open-drain FG/RD output with I²C-configurable behavior.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DRV10983ZRTVR | Integrated FETs rated for 1.5 A (vs. 2.2 A); no integrated Hall sensor - requires external rotor position feedback | Targeted at lower-power fans (<20 W); lacks I²C diagnostics and programmable LRP | Choose when cost sensitivity outweighs closed-loop precision and self-contained sensing needs |
| MP6532GQ-Z | 3-phase gate driver only - no Hall sensor, no regulation loop, no protections beyond OCP/TSD | Requires external MCU for speed control, commutation logic, and fault handling | Choose when full system-level control and flexibility are prioritized over integration and time-to-market |

FAQ
What is the maximum motor power supported by MLX90412KLW-BAH-025-RE?
The MLX90412KLW-BAH-025-RE supports up to 35 W motor loads, enabled by its 2.2 A continuous current rating and thermal design within the DFN10 package. This rating assumes proper PCB copper area for heatsinking and ambient temperatures ≤85 °C. The device remains functional up to 40 V supply transients without latch-up.
Does MLX90412KLW-BAH-025-RE require an external Hall sensor?
No. The MLX90412KLW-BAH-025-RE integrates a high-sensitivity Hall-effect sensor, eliminating the need for external rotor position sensing components. This integration simplifies layout, reduces BOM cost, and improves reliability in space-constrained applications like smart cleaner robots and toilet pumps.
How is closed-loop speed control implemented in MLX90412KLW-BAH-025-RE?
MLX90412KLW-BAH-025-RE implements closed-loop speed control using internal tachometer feedback derived from motor back-EMF and Hall sensor signals. Speed setpoints are configured via I²C, and regulation achieves ±1.5% accuracy across temperature and supply voltage variations without external compensation.
What protections are programmable on MLX90412KLW-BAH-025-RE?
MLX90412KLW-BAH-025-RE supports I²C-programmable locked rotor protection (LRP) and overvoltage protection (OVP) thresholds. Other built-in protections - including thermal shutdown (TSD), overcurrent (OCP), current limiting (CL), and open-drain FG/RD diagnostics - operate automatically but report status via the configurable output pin.
Is MLX90412KLW-BAH-025-RE qualified for consumer safety certifications?
Yes. The MLX90412KLW-BAH-025-RE is UL/VDE/CE ready and packaged in a JEDEC-qualified DFN10. Its internal protections, thermal design, and isolation meet requirements for Class II consumer appliances - accelerating certification for window air-conditioners, robotic vacuums, and smart bathroom systems.
