Product details
Overview
MLX90412KLW-BAA-045-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.
For engineers reviewing the MLX90412KLW-BAA-045-RE datasheet, pinout, applications, or equivalent options, key selection considerations include programmable locked rotor protection, wettable-flank DFN10 package compatibility with automated optical inspection, and I²C-configurable open/closed-loop mode switching for rapid prototyping and end-of-line calibration.
Technical Context
The MLX90412KLW-BAA-045-RE integrates a Hall-effect position sensor, gate driver, and motor control logic in a single die. It supports both maximum-torque and ultra-low-acoustic-noise commutation modes, with real-time current sensing enabling precise 2.2 A current limiting and short-circuit protection.
Its closed-loop speed regulation uses feedback from the integrated Hall sensor and configurable FG/RD diagnostic output, while I²C interface allows dynamic adjustment of OVP threshold (programmable), LRP timeout, and TSD trip point - all without external components.

FAQ
What is the maximum continuous motor power supported by the MLX90412KLW-BAA-045-RE?
The MLX90412KLW-BAA-045-RE supports up to 35 W continuous motor power with its 2.2 A current limit and thermal design. This rating assumes operation within the 3.5 V to 32 V supply range and proper PCB thermal management using the exposed-pad DFN10 package. Power capability scales linearly with voltage and load impedance, and the device includes current-limiting and temperature-shutdown protections to prevent damage during overload conditions. The MLX90412KLW-BAA-045-RE maintains this rating across its full operating temperature range.
Does the MLX90412KLW-BAA-045-RE require an external Hall-effect sensor?
No, the MLX90412KLW-BAA-045-RE integrates a high-sensitivity Hall-effect sensor on-die, eliminating the need for external position sensing components. This internal sensor provides rotor position feedback directly to the commutation logic and closed-loop speed controller. The HALL pin outputs a conditioned analog signal usable for external monitoring, but all core motor control functions operate autonomously. The MLX90412KLW-BAA-045-RE's integrated sensing reduces bill-of-materials count and improves system-level EMI immunity compared to discrete sensor solutions.
How is closed-loop speed control implemented in the MLX90412KLW-BAA-045-RE?
Closed-loop speed control in the MLX90412KLW-BAA-045-RE uses real-time feedback from its integrated Hall-effect sensor to calculate actual motor RPM, comparing it against the target setpoint derived from the EN pin PWM duty cycle. The control loop adjusts commutation timing and current profiles dynamically to maintain ±1.5% speed accuracy across load and supply variations. This functionality is enabled by default and does not require external components. The MLX90412KLW-BAA-045-RE also supports open-loop mode via I²C command for compatibility with legacy designs.
Can the MLX90412KLW-BAA-045-RE be used in battery-powered applications?
Yes, the MLX90412KLW-BAA-045-RE operates from 3.5 V to 32 V, making it compatible with portable systems powered by up to seven series Li-ion cells (~29 V). Its low quiescent current in standby mode and programmable FG/RD output support energy-efficient operation in battery-powered cleaners and robotics. The device's wide input range eliminates the need for intermediate regulators in multi-cell configurations. The MLX90412KLW-BAA-045-RE's thermal efficiency and integrated protections further extend usable runtime under variable load conditions.
What certifications apply to the MLX90412KLW-BAA-045-RE?
The MLX90412KLW-BAA-045-RE is UL/VDE/CE ready and packaged in a JEDEC-qualified DFN10 with wettable flanks. These qualifications confirm compliance with international safety standards for end-product certification and ensure robustness during PCB assembly and thermal cycling. The device meets AEC-Q200 stress test requirements for passive components and has been validated for use in consumer white goods and industrial equipment. The MLX90412KLW-BAA-045-RE's qualification status supports accelerated regulatory approval for final products without additional component-level testing.
