BD67173NUX
General Description
BD67173NUX is a three-phase sensorless 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 sensorless 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.
