Note 1: All voltages are referenced to ground unless otherwise noted. Currents into the IC are positive; currents out of the IC are
negative.
Note 2: During fault conditions, if AC-coupled, LCM and OVD can go below ground by up to 1V for up to 1s.
Note 3: Threshold voltage includes the DC bias-voltage offset.
