5.1

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 Section 5.2

For application with supply voltages (VCC) greater than 15 V, with low capacitive loads

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
