1. tDLY(ON) and tDLY(OFF) are turn-ON and turn-OFF propagation delay

times.

2. Turn-OFF is an output programmed from an ON to an OFF state.

3. Turn-ON is an output programmed from and OFF to an ON state.

1. tPDLY(OFF) is the output fault unlatch disable propagation delay time re-

quired to correctly report an output fault after CS rises. It represents an

output commanded ON while having an existing output short (overcurrent)

to supply.

2. The SFPD pin < 0.2 V.
