The TPS1HC30-Q1 comes with a latch functionality that decides after the channel is shut down due to a fault, whether or not to automatically try and turn back on, or stay off until other action is taken. This functionality is done by holding the LATCH pin high for latch-off functionality or holding LATCH low for auto-retry functionality.

The order the events occur is:

1. The device shuts down due to fault (thermal shutdown)
2. Wait t_RETRY
3. If LATCH = 0
   1. Turn back on the channel
4. If LATCH = 1
   1. Keep off until LATCH = 0 || EN = 0
      1. Then if LATCH = 0 and EN = 1
         1. Turn on channel into auto-retry mode
      2. If LATCH = 1 and EN = 1
         1. Turn on channel into latch mode where if another fault occurs then output is latched off again
