BD67173NUX数据手册集成电路（IC）的电机驱动器控制器规格书PDF

描述 Description

BD67173NUX is a three-phase sensor less fan motor driver used to cool off notebook PCs. It is controlled by a variable speed provided through the PWM input signal. Its feature is sensor less drive which doesn’t require a hall device as a location detection sensor and motor downsizing can be achieved by limiting the number of external components as much as possible. Furthermore, introducing a direct PWM soft switched driving mechanism achieves silent operations and low vibrations.
