Product details
Overview
MLX90412KLW-BAA-022-SP 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, including robotic vacuum cleaners and condenser dryer drain pumps.
For engineers reviewing the MLX90412KLW-BAA-022-SP datasheet, pinout, applications, or equivalent options, key selection considerations include its DFN10 3×3 mm exposed-pad package, programmable locked rotor protection, open/closed-loop PWM control interface, and UL/VDE/CE readiness for consumer-grade thermal management designs.
Technical Context
The MLX90412KLW-BAA-022-SP implements sensor-based commutation using an on-chip Hall-effect sensor and supports both open-loop and closed-loop speed regulation via external PWM input or internal I²C command. Its adaptive commutation algorithm dynamically adjusts timing across the full speed range to maximize efficiency and minimize acoustic noise.
Protection features include programmable locked rotor detection, overvoltage protection (OVP), overcurrent protection (OCP), current limiting, thermal shutdown (TSD), and diagnostic FG/RD output - all implemented in silicon without external components. The device operates from 3.5 V to 32 V and withstands transients up to 40 V.

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 |
|---|---|---|---|
| DRV10983ZRTJR | Requires external Hall sensor; no integrated sensor or I²C interface; fixed commutation timing | Lacks closed-loop speed accuracy and programmable diagnostics; suited for cost-sensitive, lower-noise-tolerance fans | Choose DRV10983ZRTJR only if sensor integration and field-programmability are not required |
| MP6532GQ-Z | Supports only open-loop control; no closed-loop speed regulation or FG/RD diagnostics; 1.8 A max current | Targeted at basic 12 V fans without acoustic or reliability requirements; no LRP or OVP programming | MP6532GQ-Z fits simple cooling needs but cannot replace MLX90412KLW-BAA-022-SP in closed-loop or safety-critical pump applications |
Compared with DRV10983ZRTJR and MP6532GQ-Z, the MLX90412KLW-BAA-022-SP delivers unique value through on-die Hall sensing, ±1.5% closed-loop speed control, and I²C-configurable protections - enabling faster time-to-market for smart appliance developers needing certified, low-noise, and field-adaptable motor control.

FAQ
What is the maximum continuous motor current supported by the MLX90412KLW-BAA-022-SP?
The MLX90412KLW-BAA-022-SP supports up to 2.2 A continuous motor current, enabling safe operation of BLDC loads up to 35 W at 24 V. This rating assumes proper PCB thermal design with the exposed pad soldered to a ≥200 mm² copper pour. Peak current capability reaches 3.5 A for short durations under defined thermal conditions.
Does the MLX90412KLW-BAA-022-SP require an external Hall-effect sensor?
No, the MLX90412KLW-BAA-022-SP integrates a high-sensitivity Hall-effect sensor on-die, eliminating the need for external position sensing components. This internal sensor provides the rotor position feedback required for sensor-based commutation and closed-loop speed control - a key differentiator from competing drivers like the DRV10983ZRTJR.
Can the MLX90412KLW-BAA-022-SP operate in both open-loop and closed-loop speed control modes?
Yes, the MLX90412KLW-BAA-022-SP supports both modes: open-loop via PWM input (1–100 kHz), and closed-loop using internal speed feedback with ±1.5% accuracy. Closed-loop mode reduces design effort for fan/pump tooling adjustments and improves response to end-customer performance requests without hardware changes.
What certifications does the MLX90412KLW-BAA-022-SP support out of the box?
The MLX90412KLW-BAA-022-SP is UL/VDE/CE ready, meeting critical safety requirements for consumer appliances including creepage/clearance distances, thermal shutdown behavior, and fault response timing. Its JEDEC-qualified DFN10 package further supports automated optical inspection and high-yield manufacturing in certified production lines.
How is diagnostic feedback provided by the MLX90412KLW-BAA-022-SP?
The MLX90412KLW-BAA-022-SP provides diagnostics via its open-drain FG/RD pin, configurable as either a tachometer output (FG) or rotor lock flag (RD). Configuration is done via I²C, allowing dynamic reassignment during system operation - for example, switching from speed monitoring to stall detection during pump priming sequences.
