|
• Full 3-phase sinusoidal drive The A5943 is a low noise, three phase motor driver with • PWM speed input integrated power bridge suitable for driving small fans and • Analog speed input blowers.
Motor audible noise and vibration is reduced by • FG speed output driving the phases with sinusoidal PWM excitation.
Motor • Lock detection current is controlled using PWM techniques to minimize the • Current limiting power dissipation.
