APPLICATION
The input signals INH and INL can be controlled
independently. If both INH and INL control the
high-side MOSFET and low-side MOSFET of the
same bridge, then users must avoid shoot
through by
setting sufficient dead time between INH and INL
low, and vice versa. See Figure 3 below. Dead
time is defined as the time interval between INH
low and INL low.
