The devices feature VDRV to PGND shootthrough protection with adaptive/adjustable
deadtime control. The deadtime, for turning on the
high-side FET from LOWDR transitioning low, is
adjustable with an external capacitor on the
DELAY pin. This allows compensation for the
effect the gate resistor has on the synchronous
FET turn off. The adaptive deadtime prevents the
turning on of the low-side FET until the voltage on …
