Note:
a. When one output (high or low side) is turned on, the other side turn-on input is ignored.
b. If both outputs are changed simultaneously, the turn-on activation is done by the internal dead time of 275ns typ.
(For more information, please refer to below ‘Dead Time’ section.)
c. When high-side (HIN) and low-side (LIN) have turn-on inputs at the same time, low-side (LIN) has the priority.
