Abstract
A half-bridge driver drives a half-bridge circuit. The half-bridge driver includes a switch selection circuit and at least one slew rate adjustment circuit, wherein the slew rate adjustment circuit includes a pulse-width control unit, an adjustment pulling unit and a halt adjustment pulling unit. The switch selection circuit generates a source current or a sink current to correspondingly pull up or pull down the gate-source voltage of the upper switch or the lower switch, thereby turning-on or turning-off the upper switch or the lower switch. The adjustment pulling unit is for adjusting the pulling-up or pulling-down of the gate-source voltage of the upper switch or the lower switch. The stop-adjustment pulling unit is for stopping adjusting the pulling-up or pulling-down of the gate-source voltage of the upper switch or the lower switch.
