space
sink, and pull-up and pull-down resistance have been
reducedto 0.9 Ω, thereby allowing for driving large
power MOSFETs with minimized switching losses
during the transition through the Miller Plateauof the
MOSFET. The input structureis now ableto directly
handle –10 VDC, which increases robustness and
also allows direct interfaceto gate-drive transformers
without using rectification diodes. The inputs are also
independentof supply voltage and havea maximum
ratingof 20-V.
