Smart Home Audio(325)


KA44169AB is a high efficiency single phase motor driver IC with built-in Soft Switching function for low noise operation. The soft switching period is automatically adjusted based on the motor current. This eliminates the need for individual adjustment of the soft switching period based on the motor’s specifications. Motor speed is controlled by DC input. With a wide input voltage range of 12V/24V, this IC is most suitable for usage in home appliances, office automation and factory automation equipment.
