Gate Output / Soft Driving

The BiCMOS output stage has a fast totem-pole gate

driver. The output driver is clamped by an internal

14.5 V Zener diode to protect the power MOSFET gate

from over voltage. A soft driving is implemented to

minimize Electromagnetic Interference (EMI) by

reducing the switching noise.
