For a gate driver application with a unipolar bias supply or a bipolar supply with a small negative turn-off voltage, an active Miller clamp can help add a additional low impedance path to bypass the Miller current and prevent the high dV/dt introduced unintentional turn-on through the Miller capacitance. Figure 7-7 shows the timing diagram for an on-chip internal Miller clamp function.
