Turn-off sequence

When one of the external MOSFET must be turned-off the gate driving circuitry starts

sinking the programmed current from the gate. At the beginning of the controlled current

expires, the Miller clamp switch is turned on (see Figure 6).

Miller plateau region. During the plateau the gate-source voltage remains constant while the

conducts the current. After the plateau region, the drain current decreases down to zero as

the gate-source voltage.
