Notes
[e-mail] [phone] option 7
1. Guaranteed by characterization test and/or analysis. Not a production test.
3. An external inhibit interface should be used to pull the inhibits low or leave them
2. Dual outputs: The over-current limit will trigger when the sum of the currents from
floating. The inhibit pins can be left unconnected if not used.
both outputs reaches 125% (typical value) of the maximum rated “total” current of
both outputs.
