General description
BD6326ANUX 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.

FEATUREs
◾ Speed controllable by PWM input signal
◾ 180° Sinusoidal drive
◾ Power save function
◾ Internal RNF resistance
◾ Motor rotation direction select function(FR)

APPLICATION
◾ Small fan motor notebook PCs etc.
