Melexis Announces Low Noise Fan Driver for Automotive Applications

Melexis, a global microelectronics engineering company, announces the introduction of the new single-coil fan driver IC, the MLX90411, which delivers 600mA at 24V or 15W for a wide range of applications requiring high performance and low noise.

The MLX90411 operates from 3V to 28V and is suitable for a wide range of applications requiring 5V, 12V and 24V, including home appliances such as air purifiers and numerous white goods. In many of these applications, AC induction motors are being replaced by brushless motors, and the preferred solution is a single-coil fan driver such as the MLX90411.

The device can withstand up to 40V load dump pulses, so in automotive applications, it can be directly connected to the battery without additional protection. With an operating temperature range of -40°C to +150°C, the MLX90411 is the world's first ASIL-compliant fan driver.

The MLX90411 features a variety of integrated protection features including locked rotor, overtemperature protection, overvoltage protection, short circuit protection and current limiting. These features not only help the MLX90411 achieve UL/CE certification, but also meet the stringent requirements of automotive applications.

For this product release, Dirk Leman, Melexis Motor Control Product Line Manager, said: “Melexis has long focused on developing single-coil fan drivers for consumer computing applications. The MLX90411 enriches our product range for home appliances Highly reliable solutions for white goods and automotive applications. The closed loop speed control and adaptive commutation control settings give designers real benefits."
