Patent ID: 8169209

Claim:
An output driving circuit capable of reducing EMI effect, comprising: a non-overlapping signal generation unit, for generating a first non-overlapping signal and a second non-overlapping signal according to an input signal; a pre-driver, coupled to the non-overlapping signal generation unit, for generating a first pre-driving signal and a second pre-driving signal according to the first non-overlapping signal and the second non-overlapping signal; a high-side switch, comprising a first terminal coupled to the pre-driver for receiving the first pre-driving signal, a second terminal coupled to a first power end, and a third terminal for controlling an electrical connection between the second terminal of the high-side switch and the third terminal end of high-side switch; a low-side switch, comprising a first terminal coupled to the pre-driver for receiving the second pre-driving signal, a second terminal, and a third terminal coupled to a ground end for controlling an electrical connection between the second terminal of the low-side switch and the third terminal end of the low-side switch; an output end, coupled to the third terminal of the high-side switch, the second terminal of the low-side switch, and a load, for outputting an output signal; and a control unit, coupled to the non-overlapping signal generation unit, the high-side switch, and the low-side switch for controlling the high-side switch or the low-side switch to be switched into a weak on state to reduce load inductive current effect caused by the load according to the first non-overlapping signal, the second non-overlapping signal, the first pre-driving signal and the second pre-driving signal.
