Product details
Overview
MLX90412GLW-BAX-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 capability, 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 MLX90412GLW-BAX-042-RE datasheet, pinout, applications, or equivalent options, key selection considerations include its DFN10 3×3 exposed-pad package, programmable locked rotor protection, PWM and I²C control interfaces, and UL/VDE/CE-ready certification for consumer and white-goods applications.
Technical Context
The MLX90412GLW-BAX-042-RE implements sensor-based commutation using an integrated Hall-effect position sensor and supports both open-loop and closed-loop speed regulation via internal PID control. Its adaptive commutation algorithm dynamically adjusts timing to maximize efficiency and minimize acoustic noise across the 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. The FG/RD diagnostic output provides open-drain status reporting for fault conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 3.5 V to 32 V; robust to 40 V transient - supports 12 V/24 V systems and portable Li-ion stacks up to ~29 V. |
| Max Motor Current | 2.2 A continuous - enables safe driving of up to 35 W loads without thermal derating in DFN10 package. |
| Speed Control Accuracy | ±1.5% in closed-loop mode - eliminates need for mechanical tuning of fan/pump tooling to meet target RPM. |
| Commutation Modes | Maximum torque or ultra-low acoustic noise - selectable per application acoustic or performance requirement. |
| Diagnostic Output | FG/RD open-drain pin - reports faults (LRP, OVP, TSD, OCP) with programmable polarity and pulse width. |
| Programming Interface | I²C (fast-mode plus, 1 MHz) - enables end-of-line calibration, firmware updates, and fast prototyping without external programming hardware. |

FAQ
What is the maximum motor power the MLX90412GLW-BAX-042-RE can drive safely?
The MLX90412GLW-BAX-042-RE supports up to 35 W motor loads with continuous 2.2 A current capability and thermal protection. Its DFN10 package with exposed thermal pad ensures safe operation under sustained load in ambient temperatures up to 105 °C - verified per JEDEC qualification standards. This makes MLX90412GLW-BAX-042-RE ideal for compact, high-efficiency fan and pump modules.
Does the MLX90412GLW-BAX-042-RE require an external Hall sensor?
No - the MLX90412GLW-BAX-042-RE integrates a high-sensitivity Hall-effect sensor on-die, eliminating the need for external position sensing components. This integration simplifies PCB layout, reduces system cost, and improves reliability. The MLX90412GLW-BAX-042-RE uses this internal sensor for precise rotor position detection in both open-loop and closed-loop commutation modes.
Can the MLX90412GLW-BAX-042-RE operate from a 7-cell Li-ion battery pack?
Yes - the MLX90412GLW-BAX-042-RE operates from 3.5 V to 32 V and is robust up to 40 V, making it compatible with nominal 29 V (7S) Li-ion battery packs. Its wide input range and built-in overvoltage protection (OVP) ensure safe operation during charge peaks and load-dump transients common in portable applications like robotic vacuum cleaners.
How is speed controlled on the MLX90412GLW-BAX-042-RE?
Speed is controlled via either PWM input (100 Hz–20 kHz) for open-loop operation or I²C commands for closed-loop regulation with ±1.5% accuracy. The MLX90412GLW-BAX-042-RE's internal PID controller uses feedback from the integrated Hall sensor to maintain precise RPM regardless of voltage or load variation - a key advantage over basic PWM-only drivers.
What certifications does the MLX90412GLW-BAX-042-RE support for end-product compliance?
The MLX90412GLW-BAX-042-RE is UL/VDE/CE ready and housed in a JEDEC-qualified DFN10 package. Its design meets essential safety and EMC requirements for Class B consumer appliances, enabling faster regulatory approval for products such as smart air conditioners, toilet pumps, and condenser dryers - without requiring additional isolation or filtering components.
