Operational Waveforms
At power-up, the driver output remains LOW until the
V
magnitude of the OUT pulses rises with V
steady-state
operation illustrated in Figure 32 shows that the output
remains LOW until the UVLO threshold is reached, then
the output is in-phase with the input.

The inverting configuration of startup waveforms are
shown in Figure 33. With IN+ tied to VDD and the input
signal applied to IN–, the OUT pulses are inverted with
respect to the input. At power-up, the inverted output
remains LOW until the V
threshold, then it follows the input with inverted phase.
