Figure 15.2 High-current power stage using external gate drivers with short to GND protection
When using high-current gate drivers, pay special attention to manufacturers’ recommendations and
application notes, especially concerning placement and layout of the circuit and additional parts not
shown in the example figures, such as capacitors for supply voltage decoupling, protection diodes
required in combination with some MOSFETs, etc.
