DESCRIPTION
The A5932 three-phase motor controller incorporates sinusoidal drive to minimize audible noise and vibration for high-power fans.
A sinusoidal voltage profile is applied to the windings of the motor at startup to quietly start up and gradually ramp up the motor to desired speed.
The motor speed is controlled by applying a duty cycle mand to the speed (SPD) input. The SPD input is allowed to operate over a wide frequency range.
The A5932 is available in a 24-contact 4 mm × 4 mm QFN with exposed thermal pad (suffix ES), a...
