NOTES:
8. Each Output has Over Current Shutdown protection in the positive current direction. The maximum peak current rating is set equal to the
minimum Over Current Shutdown as detailed in the Electrical Specification Table. In the event of an Over Current Shutdown the input
drive is latched OFF. The output short must be removed and the input toggled OFF and ON to restore the output drive.
9. The “Low V
CC
Shutdown” is an internal control that switches off all power drive stages when V
CC
is less than V
CC(LOW)
.
10. Measurement includes the Filter Time.
