Abstract
According to an embodiment, single phase motor drive circuit includes a counter unit, an energization pattern generation unit, and a drive unit. The unit counts a time of phase switching of a Hall signal based on a clock signal. The energization pattern generation unit generates an energization pattern based on the count result of the counter unit. The drive unit generates a pulse width modulation (PWM) signal based on a duty setting signal and the energization pattern signal to output an output signal to drive a single phase motor based on the PWM signal.
