Description

Top Features

Packaging

The A5943 is a low noise, three phase motor driver with integrated power bridge suitable for driving small fans and blowers. Motor audible noise and vibration is reduced by driving the phases with sinusoidal PWM excitation. Motor current is controlled using PWM techniques to minimize the power dissipation.

  • 180° sinusoidal drive - low audible noise and vibration
  • Motor position using external Hall sensors

16-pin TSSOP with exposed thermal pad (suffix LP)
