tdly(on)

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 required to

correctly report an output fault after CS rises. It represents an output command-

ed ON while having an existing output short (over current) to supply.

2. The SFPD pin < 0.2 V
