Notes:

1
Inputs below 6 V reduce the maximum settable current limit. With 4.5 V in the maximum settable limit is 1.75 A.
2
Not intended for use with 48V batteries, which can be well above nominal when fully charged.
3
Without a heat sink or forced air flow.
4
With sufficient additional cooling.
5
Logic high threshold varies for two-state, tri-state, and quad-state pins. See datasheet for details.
6
Absolute maximum voltage on any input is 5.75 V.
