strongly recommended that this input be connected to external logic level to avoid erroneous
operation due to capacitive noise coupling.
Dead time programming input. The value of the resistor connected from DT to ground sets the
dead time between output transitions of VOA and VOB. Defaults to 1 ns dead time when con-
nected to VDDI or left open (see "3.8.Programmable Dead Time and Overlap Protection" on
page 26).
No connection.
