Power Supply Current
The Electrical Characteristics table specifies the supply
current while the part is idle (waiting for an input transi-
tion). IS(IDLE) varies with the programmed tDELAY and the
supply voltage, as described by the equations in Table 2,
valid for both the LTC6994-1 and LTC6994-2.

When an input transition starts the delay timing circuity,
the instantaneous supply current increases to IS(ACTIVE).
IS(ACTIVE) = IS(IDLE) + IS(ACTIVE)

IS(ACTIVE)canbeestimatedusingtheequationsinTable 3,
assuming a periodic input with frequency fIN. The equa-
tions assume the input pulse width is greater than tDELAY;
otherwise, the output will not transition (and the increase
in supply current will be less).

Figures 14 and 15 show how the supply current increases
from IS(IDLE) as the input frequency increases. At higher
NDIV settings, the increase in active current is smaller.
