NOTES:
7. Parameters with MIN and/or MAX limits are 100% tested at +25°C, unless otherwise specified. Temperature limits established by characterization
and are not production tested.
8. This is the V DD current consumed when the device is active but not switching. Does not include gate drive current.
9. Limits established by characterization and are not production tested.
10. Adjust V DD above the start threshold and then lower to 15V.
