Web25 sep. 2024 · About FET turn on/off delay time, If these time exceed the dead time, it is possible that 2 FETs (high/low side) become “ON” at same time. As a result, FETs might be destroyed by the shoot-through currents. When choice external FET, they should need to consider the turn on/off delay time. (These need less than the dead time.)
