SUSTAIN DRIVING CIRCUIT AND METHOD

摘要

The invention relates to a sustain driving circuit, including: a first driving switch that receives a voltage corresponding to a sustain high logic signal so as to be turned on; a first comparator that receives and compares the voltage corresponding to the sustain high logic signal and to a sustain low logic signal, and outputs a high signal when the voltage corresponding to the sustain high logic signal is higher than the sustain low logic signal; and a first protection circuit including a first transistor that is electrically connected between the first comparator and the first driving switch, and receives the high signal from the first comparator so as to be turned on.
