Notes

18.

Output OFF OpenLoad Detection Current is the current required to flow through the load for the purpose of detecting the existence of

an OpenLoad condition when the specific output is commanded OFF. Pull-up current is measured for VHS = VOLD(THRES)

19.

Current sense ratio = ICSNS / IHS[0:3]
