Nuvoton KA44170A Bruschless Motor Driver IC

KA44170A is a high efficiency single phase motor driver IC with built-in Soft Switching function for low noise operation.

An automatic phase adjustment function is provided to optimize the soft switching section and its current, so it is possible to drive the motor with low noise and high efficiency regardless of the type of motor and operating environment with a small number of components.

Motor speed is controlled by direct PWM 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 (for high speed fan motor < 15krpm) equipment.
