The total IC power dissipation can be estimated from the
above plots by summing the gate drive losses with the
bootstrap diode losses for the intended application. Because
the diode losses can be significant, an external diode placed
in parallel with the internal bootstrap diode (refer to
Figure 4
)
can be helpful in removing power from the IC. For this to be
effective, the external diode must be placed close to the IC to
minimize series inductance and have a significantly lower
forward voltage drop than the internal diode.
