Abstract
A motor driver for adjusting power based on a common voltage is provided. The motor driver includes a common voltage difference calculation circuit, a duty cycle determination circuit, a signal generator circuit, a control circuit, a driver circuit and an output stage circuit. The common voltage difference calculation circuit calculates a difference between the common voltage received by the output stage circuit and a threshold. The duty cycle determination circuit determines a duty cycle adjustment value according to the difference. The signal generator circuit adjusts a plurality of waveform signals according to the duty cycle adjustment value. The control circuit outputs control signals according to the plurality of waveform signals. The driver circuit outputs driving signals according to the control signals. The output stage circuit operates to drive the motor according to the common voltage and the driving signals.
