Below-ground voltage spikes
As explained in the previous section, the dynamic contribution of the below-ground voltage
on the OUT pin does not have enough time to overcharge the bootstrap capacitor. This fact
usually excludes the risk of exceeding the recommended maximum value of 20 V for the
VBOOT -VOUT voltage, but on the other hand it increases the danger of pulling the BOOT pin
down below ground, then violating its absolute minimum rating. As mentioned above, for
safe operation of the IC gate driver, this phenomenon should be avoided. However, note that
applicative bench tests have shown that the L6393 also works with below-ground spikes on
the OUT pin that well exceed -50 V (see Figure 36).
