Abstract
A brushless motor drive circuit has a first AD converter which converts a voltage value depending upon a power supply voltage supplied from a power supply to drive a three-phase brushless motor, to a digital signal and outputs the digital signal. The brushless motor drive circuit has an energization timing adjustment circuit which outputs an adjustment signal for adjusting a lead angle value or a lag angle value of energization timing of the three-phase brushless motor, in response to the digital signal which is output by the first AD converter. The brushless motor drive circuit has an energization timing setting circuit which sets the energization timing of the three-phase brushless motor.
