Sequencing and Tracking
Figure 25. Turn-Off Delay Register DOF
Turn-on delay, turn-off delay, and rising and falling
output voltage slew rates can be programmed in the
GUI Sequencing/Tracking window shown in Figure
23 or directly via the I 2 C bus by writing into the DON,
DOF, and TC registers, respectively. The registers
are shown in Figure 24, Figure 25, and Figure 27.
Turn-off delay is defined as an interval from the
application of the Turn-Off command until the output
voltage reaches zero (if the falling slew rate is
programmed) or until both high side and low side
switches are turned off (if the slew rate is not
programmed). Therefore, for the slew rate controlled
turn-off the ramp-down time is included in the turn-off
delay as shown in Figure 26.

8.2.1 Turn-On Delay
Turn-on delay is defined as an interval from the
application of the Turn-On command until the output
voltage starts ramping up.
Figure 26. Relationship between Turn-Off Delay and Falling
Slew Rate
As it can be seen from the figure, the internally
calculated delay T D is determined by the equation
below.

For proper operation T D shall be greater than zero.
The appropriate value of the turn-off delay needs to
be programmed to satisfy the condition.
