Abstract:
The present invention discloses a start-up circuit for a motor driving IC. The activation circuit includes a determination unit, for generating a determination result indicating an operating mode of the motor driving IC according to an external pulse width modulation signal, and an output unit, for outputting an activation signal according to the determination result and a pulse width modulation activation signal. A duty of the pulse width modulation activation signal is greater than a duty of the external pulse width modulation signal.
