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.
