Output series resistance
An output resistance is generally introduced to allow high frequency operation without
exceeding the maximum power dissipation of the driver package.
The value of the output resistance can be obtained as described in
For application with supply voltages (VCC) greater than 15 V, with low capacitive loads
(C
In these circumstances, due to its high peak current capability, severe undervoltage on the
output pins may occur, which, if not limited in some way, can violate the safe operating area
of the output stage of the device.To avoid this phenomena it is mandatory to add a gate
resistor R
