Melexis MLX90411 Single Coil Fan Driver ICs

Melexis MLX90411 Single Coil Fan Driver IC can deliver 600mA at 24V or 15W and is ideal for a broad range of applications that need high performance with low noise operation. Melexis MLX90411 runs from a supply voltage of 3V to 28V, making it ideal for all applications that need a supply of 5V, 12V, or 24V. This includes home appliances such as air purifiers and many white goods. In automotive applications, the device can be directly connected to the battery without additional protection due to its capacity to withstand load dump pulses up to 40V. The ASIL-ready fan-driver can run over a temperature range of -40°C to +150°C. The closed-loop speed control and adaptive commutation control deliver real benefits to designers.
