Passes 2000 volts. 3. Dual outputs: The over-current limit will trigger when the sum of the currents from both outputs reaches 115% (typical value) of the maximum rated “total” current of both outputs. 4. Tested with inhibit pin pulled to ground. 5. An external inhibit interface should be used to pull the inhibit low or leave it floating. The inhibit pin can be left unconnected if not used.
