Abstract:
An output driving circuit capable of reducing EMI effect includes 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 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, a low-side switch, and a control unit 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 for a load.
