A5943中文资料A5943: Three Phase Sinusoidal Fan Driver数据手册Allegro规格书

描述 Description

The A5943 is a low noise, three phase motor driver withintegrated power bridge suitable for driving small fans andblowers. Motor audible noise and vibration is reduced bydriving the phases with sinusoidal PWM excitation. Motorcurrent is controlled using PWM techniques to minimize thepower dissipation.
Additional product technical information and datasheets are available by contacting the Allegro Factory.
