Product details

Description

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.
