Patent ID: 8907605

Claim:
A circuit structure enabling upgraded MOS transistor heat dissipation ability and applied to a motor, comprising: a motor driving unit including a first switch, a second switch, a third switch and a fourth switch, which respectively have a first terminal end, a second terminal end and a third terminal end; the first and the third switch being connected at their third ends to the third ends of the second and the fourth switch, respectively; and the first and the second switch being connected at their second ends to the second ends of the third and the fourth switch, respectively; and a signal processing unit including: a first voltage stabilizer having an end connected to the first end of the first switch and another end connected to the second end of the first switch and an input voltage for stabilizing a voltage between the first end and the second end of the first switch; a second voltage stabilizer having an end connected to the first end of the third switch and another end connected to the second end of the third switch and the input voltage for stabilizing a voltage between the first end and the second end of the third switch; a first booster connected to the first end of the second switch for boosting a received first signal and outputting the boosted first signal to the first end of the second switch; and a second booster connected to the first end of the fourth switch for boosting a received second signal and outputting the boosted second signal to the first end of the fourth switch.
