Abstract
A motor driver having a high success rate starting mechanism is provided. A multi-segment slope pattern circuit connects a plurality of values of waveforms of a starting waveform signal to form a curve. The multi-segment slope pattern circuit determines a plurality of slopes respectively of a plurality of curve segments included in the curve according to a plurality of parameters related to a motor. The multi-segment slope pattern circuit outputs a multi-segment slope pattern signal according to the plurality of slopes of the plurality of curve segments. A startup signal generating circuit outputs a first startup waveform signal according to the multi-segment slope pattern signal. A motor controller circuit controls a motor driving circuit to start up the motor according to the first startup waveform signal.
