NOTES:
7. Specifications at -55°C and + 125°C are guaranteed by +25°C test with margin limits.
8. This is the V DD current consumed when the device is active but not switching. Does not include gate drive current.
9. These parameters, although guaranteed, are not 100% tested in production.
10. Adjust V DD above the start threshold and then lower to 15V.
