NOTES:

1. Percentage of Full Scale (F.S.) with temperature compensation applied.

4. Automatically set to same value as soft start ramp time.

5. Limits established by characterization and not production tested.

6. Compliance to datasheet limits is assured by one or more methods: production test, characterization and/or design.
