FUNCTIONAL DESCRIPTION

The MSX70 is a three-phase sin wave BLDC driver IC. It is based on 3 external hall sensor signal and it drives sinusoidal wave current. It can drive the motor under 30W with 1.5A continuous current. It is also built in a AC motor driver to drive 12V or 24V synchronous swing motor. Compensation for different hall sensor type, position and polarity can be made for driving performance. Lead angle and protection parameter can also be saved in the chip through I2C. It is suitable for the pedestal fan, circulation fan to simplify driver board design and minimize passive component.
