BH6717NUV

DC Brushless Motor Drivers for Cooling Fans Three-Phase Full-Wave Fan Motor Driver for Note PC BH6717NUV No.12010EAT18 ●Description 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 possible. Furthermore, introducing a direct PWM soft switched driving mechanism achieves silent operations and low vibrations. ●Features 1) Speed controllable by PWM input signal 2) Sensorless drive 3) Soft switched drive 4) Power save function ●Applications small fan motor notebook PCs etc ●Absolute maximum ratings(Ta=25C) Parameter Symbol Ratings Supply voltage VCC −0.3～6.5 Power dissipation Pd 560 * Operating temperature Topr -25～+95 Storage temperature Tstg -55～+125 ...
