Abstract
A driving circuit for a single-phase-brushless motor and a method that includes a driving-signal-generating circuit configured to generate a driving signal for supplying, to a driving coil of the single-phase brushless motor, an output circuit coupled to the driving signal generating circuit; and an induced voltage zero-cross detecting circuit having a plurality of inputs and an output, a first input coupled to the driving signal generating circuit and configured to detect a zero cross of an induced voltage in response to operation in the de-energized period.
