KA44171A

KA44171A is Pre Driver IC for single phase Brushless Motor. it can apply DC or PWM signal for Motor speed control input. PWM soft switching function and Motor current phase setting can makes Motor current direction switch smoothly, high efficiency and silent driving.

Wide supply voltage range can use various external power MOSFET. it can drive various Motor using 12V,24,and 48V power supply.

KA44171A is equipped with APRaS (Advanced Phase and Rapid Soft switching) to optimize high speed motor performance.

With a wide input voltage range of 12V/24V and 48V, this IC is most suitable for usage in Industrial for data sever, base station, HA, OA and FA (for high speed fan motor < 100krpm) equipment.
