Product details
Overview
MLX90412GLW-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, such as robotic vacuum cleaners and condenser dryer drain pumps.
For engineers reviewing the MLX90412GLW-BAA-042-RE datasheet, pinout, applications, or equivalent options, key selection considerations include closed-loop speed tolerance, programmable locked rotor protection, wettable-flank DFN10 package compatibility, and I²C-based end-of-line calibration capability.
Technical Context
The MLX90412GLW-BAA-042-RE implements sensorless commutation using an integrated Hall-effect latch and closed-loop speed regulation via FG/RD feedback. It supports both open-loop and closed-loop modes, with ±1.5% speed accuracy in closed-loop operation across full speed range.
It features programmable protections including locked rotor detection (LRP), overvoltage (OVP), thermal shutdown (TSD), and short-circuit current limiting (OCP), all configurable via I²C interface. The device operates from 3.5 V to 32 V supply and withstands transients up to 40 V.
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 with 40 V transient robustness. |
| 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 to meet target RPM in fan/pump tooling. |
| Commutation Mode | Adaptive low-noise commutation - reduces acoustic emissions across full speed range for quiet smart appliances. |
| Interface | I²C programming interface - allows fast prototyping and end-of-line calibration of LRP, OVP, TSD, and FG output behavior. |
| Package | DFN10 3×3 mm with wettable flanks - enables automated optical solder-joint inspection and compact PCB layout. |
Pinout & Package
MLX90412GLW-BAA-042-RE is housed in a 10-pin exposed-pad DFN package (3 mm × 3 mm, <1 mm height) with wettable flanks for AOI-compatible assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Power supply input | Connects to 3.5–32 V rail; internal regulator powers logic and sensor circuitry. |
| GND | Ground reference | Common return path for power, motor, and logic sections; tied to exposed thermal pad. |
| OUT_H | High-side driver output | Drives upper MOSFET in half-bridge configuration; rated for 2.2 A continuous. |
| OUT_L | Low-side driver output | Drives lower MOSFET; complements OUT_H for synchronous commutation. |
| HALL | Hall sensor input | Accepts signal from integrated Hall-effect latch; enables sensor-based commutation timing. |
| FG/RD | Open-drain diagnostic output | Programmable fault indicator (e.g., LRP, OCP) or tachometer feedback (FG mode). |
| EN | Enable input | Active-high digital control for standby mode entry/exit; reduces quiescent current to <100 µA. |
| SCL / SDA | I²C bidirectional interface | Configures protection thresholds, commutation mode, and speed setpoints without external MCU firmware changes. |
Key Features
| Feature | Design Value |
|---|---|
| All-in-one BLDC driver with integrated Hall sensor | Eliminates need for external position sensor and discrete gate drivers, reducing BOM count by ≥4 components. |
| Adaptive commutation algorithm | Maintains peak efficiency (>85%) and minimal acoustic noise across 1,000–15,000 RPM range for diverse fan/pump impeller profiles. |
| Programmable locked rotor protection (LRP) | Detects stalled motor within 500 ms and shuts down safely - prevents coil burnout during startup or obstruction events. |
| I²C-configurable diagnostics (FG/RD) | Enables OEM-specific fault reporting (e.g., "pump blocked" vs "overtemperature") via single open-drain pin. |
| UL/VDE/CE-ready certification support | Meets safety requirements for Class II portable and fixed appliances without additional isolation components. |
Applications
| Robotic Vacuum Cleaner | Condenser Dryer Drain Pump |

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 |
|---|---|---|---|
| DRV10983ZRTVR | Requires external Hall sensor; no integrated latch; 1.5 A max current; no I²C programmability. | Lacks closed-loop speed accuracy (±5%) and programmable diagnostics; suited for cost-sensitive, non-smart fans. | Select DRV10983ZRTVR only when system-level sensor placement allows external Hall integration and ±5% speed tolerance is acceptable. |
| MP6532GQ-Z | Integrated Hall sensor; 2.5 A current limit; no I²C interface; analog PWM-only control; fixed OVP threshold. | Supports higher current but lacks field-updatable protection settings; limited to basic pump/fan designs without diagnostic reporting. | Choose MP6532GQ-Z where higher peak current is critical and firmware-free operation is preferred, but accept reduced configurability vs MLX90412GLW-BAA-042-RE. |
Compared with DRV10983ZRTVR and MP6532GQ-Z, the MLX90412GLW-BAA-042-RE uniquely combines integrated Hall sensing, ±1.5% closed-loop accuracy, I²C-based protection reconfiguration, and wettable-flank DFN packaging - enabling smaller, quieter, and field-serviceable smart appliance motor systems.

The MLX90412GLW-BAA-042-RE supports up to 2.2 A continuous motor current, enabling safe operation of BLDC loads up to 35 W at 24 V. This rating is validated under JEDEC-standard thermal conditions with the exposed-pad DFN10 package mounted on a 2-layer PCB with 1 oz copper and 1 cm² thermal pad area.
Does the MLX90412GLW-BAA-042-RE require an external Hall-effect sensor?
No, the MLX90412GLW-BAA-042-RE integrates a high-sensitivity Hall-effect latch directly into the die, eliminating the need for external position sensing components. This integration reduces system cost and board space while improving commutation timing accuracy compared to discrete sensor solutions.
How does closed-loop speed control work in the MLX90412GLW-BAA-042-RE?
The MLX90412GLW-BAA-042-RE uses FG/RD pin feedback to measure actual motor speed and dynamically adjusts PWM duty cycle to maintain ±1.5% accuracy versus the target RPM. This closed-loop operation is enabled via I²C command and requires no external microcontroller intervention once configured.
Can the MLX90412GLW-BAA-042-RE be used in 28 V systems like smart toilet pumps?
Yes, the MLX90412GLW-BAA-042-RE operates from 3.5 V to 32 V and is rated for 40 V transients, making it fully compatible with 28 V nominal systems such as smart toilet pumps powered by multi-cell Li-ion packs. Its programmable OVP threshold ensures reliable operation across varying battery states of charge.
What certifications does the MLX90412GLW-BAA-042-RE support out of the box?
The MLX90412GLW-BAA-042-RE is UL/VDE/CE ready and packaged in a JEDEC-qualified DFN10. Its integrated protections - including programmable LRP, TSD, and OVP - satisfy core functional safety requirements for Class II household appliances per EN 60335-1, reducing time-to-certification for end products.
