BH67172UX 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.
Speed controllable by PWM input signal Sensorless drive Soft switched drive Quick start Power save function Internal RNF resistance Quick start function
