Overview
The MLX90412KLW-BAA-022-SP is a single-coil fan driver integrated circuit manufactured by Melexis. It operates within a supply voltage range of 3.5 V to 32 V and delivers an output current of 2.2 A. The device utilizes a DFN-WF-10 package with SMD/SMT mounting style. Designed for consumer applications, it supports open-loop control and includes features such as frequency generation (FG) and a 1/16 resolution interface.
Feature Summary
- Integrated single-coil fan driver with built-in high-sensitivity Hall effect sensor
- Supports I2C and PWM interfaces for flexible control and configuration
- Includes on-chip EEPROM for persistent storage of configuration settings
Applications
- Consumer electronics cooling systems
- Single-coil fan and pump drive applications
- Motor control in compact electronic devices
Procurement Notes
Verify the specific suffix BAA-022-SP against the official datasheet to confirm the exact electrical characteristics and pinout compatibility. Ensure that the DFN-WF-10 package dimensions align with your PCB footprint requirements. Check for RoHS compliance status and moisture sensitivity level (MSL) ratings prior to assembly planning. Confirm availability through authorized distributors as this component may have limited stock or be subject to order restrictions.
Selection Notes
Select this component when a low-profile solution for single-coil fan driving is required in consumer applications. The 2.2 A output current capability suits moderate power fans operating up to 32 V. Consider the DFN-WF-10 package for space-constrained designs. Verify that the open-loop control mode meets the application's speed regulation needs without additional feedback sensors beyond the integrated Hall element.
