AEC-Q100 qualified – K version Sinusoidal Drive For Low Audible Noise Quiet StartUp Proprietary High Efficiency Control Algorithm The A5939/A5949 three phase motor controller incorporates sinusoidal drive to minimize audible noise and vibration for high power fans.
Adjustable Current Source Based Gate Drive Speed Input • PWM – A5949 A sinusoidal voltage profile is applied to the windings of the motor at startup to quietly startup and gradually ramp up the motor to desired speed.
• Analog – A5939 Windmill Detection Hall Element or Hall Latch Compatible FG Speed Output Lock Detection For A5949, The motor speed is controlled by applying a Duty cycle command to the SPD input The SPD input is allowed to operate over a wide frequency range.
A5949/A5939 Three Phase Sinusoidal Fan Controller.
