BH6717NUV Three-Phase Full-Wave Fan Motor Driver for Note PC

BH6717NUV 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 possi.
