is negative edge triggered. There is no time delay when the inputs rise above the UVLO threshold.
Note 2: The current threshold when the output current starts to fold back. See the Typical Operating Characteristics.
Note 3: t

is negative edge triggered. ON_ or AUXON_ transition from low to high has no delay.
Note 4: Temperature threshold at which the outputs of the channel with overcurrent shut down.
Note 5: The temperature threshold at which both channels shut down.
