Note 1:
Note 2:
The soft-start fault current is the current sink capability of SS when V
REF
< 1V or when the device is in shutdown.
I
SUPP
is the supply current drawn by V+, which includes the current drawn by the charge pump. The charge pump
doubles the current drawn by HIGH from the V+ input, so I
SUPP
= I

+ 2I
