摘要:
There are provided a driving circuit, a driving module, a motor driving apparatus capable of adjusting a driving current driving a power semiconductor device, the driving circuit including a driving unit including a plurality of drivers and selecting a corresponding driver among the plurality of drivers according to a selection signal to determine a current level of a driving signal for driving a semiconductor device, a timing controlling unit detecting a phase shift time of the driving signal transferred to the semiconductor device and comparing the detected time with a preset reference time to control the phase shift time of the driving signal, and a driving controlling unit providing the selection signal for selecting a driver to be driven among the plurality of drivers of the driving unit according a control signal from the outside and a timing control signal of the timing controlling unit.
